Abstract:
The experiment tested the hypothesis that the acetylcholine (ACh) release in the rat auditory cortex is greater in rats undergoing auditory classical conditioning compared to rats in a truly random control paradigm where no associative learning takes place and that this is mediated by prefrontal afferent projections influencing the nucleus basalis magnocellularis (NBM), which in turn modulates ACh release in neocortex. Rats with bilateral ibotenic acid lesions of medial prefrontal and agranular insular cortices were tested in an auditory classical conditioning task while ACh was collected from the primary auditory cortex. It was hypothesized that lesions of these prefrontal areas would prevent learning-related increases of ACh release in the primary auditory cortex. The hypothesized results were supported. Results from this experiment provide unique evidence that medial prefrontal cortex projections to the NBM are important for mediating cortical ACh release during associative learning.

Abstract:
An animal's own behaviour can give rise to sensory stimulation that is very similar to stimulation of completely external origin. Much of this self-induced stimulation has little informative value to the animal and may even interfere with the processing of externally-induced stimulation. A high-level association area in the temporal cortex of macaque (superior temporal polysensory area, STP) which has been shown to participate in the analysis of visual motion was targeted in a series of experiments in order to investigate whether this brain area discriminates externally- and self-induced stimulation in its visual motion processing. Earlier results in somatosensory processing within this same brain area provided grounds for this presumption The cells studied in here were sensitive to the presence of motion but showed no selectivity for the form of the stimulus. 25% of all visually responsive cells in area STP were classified as belonging to this class of cells. This group of cells was further categorized into unidirectional (39%), bidirectional (4%) and pandirectional (57%) cells. Tuning to direction varied in sharpness. For most cells the angular change in direction required to reduce response to half maximal was between 45 and 70 degrees. The optimal directions of cells appeared clustered around cartesian axes, (up/down, left/right and towards/away). The response latency varied between 35.0-126.4 ms (mean 90.9 ms). On average cell responses showed a transient burst of activity followed by a tonic discharge maintained for the duration of stimulation. 83% of the motion sensitive cells lacking form selectivity responded to any stimuli moved by the experimenter, but gave no response to the sight of the animal's own limb movements. The cells remained, however, responsive to external stimulation while the monkey's own hand was moving in view. Responses to self-induced movements were recovered if the monkey introduced a novel object in its hand into view. That the response discrimination between externally- and self-induced stimulation was not caused by differences in the visual appearance of the stimuli was confirmed in the second experiment where the monkey was trained to rotate a handle connected to a patterned cylinder in order to generate visual motion stimulation over a fixation point. 61% of the tested cells discriminated between pattern motion generated by the monkey and by the experimenter. It was shown that the monkey's motor activity as such (turning a handle without visible cylinder rotation) did not affect the cells' spontaneous activity. Some indication was received to suggest that the discriminative mechanism is using not only (motor) corollary discharges but also proprioceptive input. These results also gave evidence of the plasticity of discriminative processing in STP for the animal's life-time experiences. Finally, the cells were studied for their responsiveness for image motion resulting from movements of external objects and movements of the animal's body (self-motion). 84% of the cells responded only to visual object-motion and failed to respond to visual motion resulting from animal's self-motion. The experiments also revealed that area STP processes visual motion mostly in observer- relative terms, i.e. in reference to the perceiver itself. The results provide one explanation for the functional significance of the convergence of several modalities of sensory (and motor) input in the STP. It is suggested that area STP works as a "neural filter" to separate expected sensory consequences resulting from one's own actions from those that originate from the actions of other animals or environmental events.

Abstract:
The study of patients has shown that certain higher cognitive processes, such as those involved in the monitoring and the manipulation of information within working memory, depend on the integrity of both the dorsolateral frontal cortex and the medial temporal lobe memory system, as well as on their functional interaction (Petrides, 1994). Small surgical removal of the anterior temporal region, including the entorhinal cortex, is not sufficient to interrupt that fronto-hippocampal relationship. More extensive removals, however, that include a sizeable portion of the hippocampus and the surrounding parahippocampal cortex do disrupt such a fronto-hippocampal functional interaction (Petrides and Milner, 1982). Based on these data, it was postulated that the fronto-hippocampal functional interaction is not entirely dependent upon the integrity of the entorhinal cortex. To test this hypothesis, injections of tritiated amino acids were placed within individual cytoarchitectonic units of the frontal cortex, and the resulting labeling in the hippocampal region was analyzed. It was shown that the mid-dorsolateral frontal cortex, together with its medial cortical extension, is the only frontal region that sends efferent fibers, running caudally as part of the cingulum bundle, to the presubiculum, the posterior parahippocampal gyrus, as well as to the retrosplenial cortex. A light contingent of these fibers, congregating in the outermost layer of both the retrosplenium and the presubiculum, course into the molecular layer of the hippocampus proper. In complete agreement with the work with patients, these findings have confirmed the hypothesis that the mid-dorsolateral frontal cortex is closely affiliated with the hippocampal system, and demonstrated that this hodological relationship bypasses the entorhinal cortex.<br>Another major contribution of the present work has been to provide the first architectonic analysis of a gross morphological region, referred to as the caudomedial lobule, which receives inputs from the mid-dorsolateral frontal cortex and its medial extension. This architectonic analysis has revealed that the caudomedial lobule is nothing but the postero-ventral extension, below the splenium of the corpus callosum, of areas 29 and 30, which together form the retrosplenial cortex, and of area 23, which partly forms the posterior cingulate cortex. Among the cortical fields that comprise the postero-ventral part of the retrosplenial cortex, area 30 is the major recipient of the mid-dorsolateral frontal inputs.<br>By virtue of the close anatomical relation of area 30 with the mid-dorsolateral frontal cortex and its medial extension, it is suggested that this part of the retrosplenial cortex may be a critical relay-station along the dorsomedially directed fronto-hippocampal pathway. In order to validate this hypothesis, the connections of area 30 were investigated by placing injections of anterograde and retrograde tracers within the limits of this retrosplenial area. This study has demonstrated that area 30 is bi-directionally connected with and only with that part of the lateral frontal cortex that lies above the sulcus principalis, namely the mid-dorsolateral frontal cortex, along with all the structures of the posterior hippocampal region that are the recipients of the inputs from the mid-dorsolateral frontal cortex. Since the fronto-hippocampal association fiber system described in the present thesis is most probably subserving certain aspects of working memory, area 30, by virtue of its bi-directional connections with both the mid-dorsolateral frontal cortex and the posterior parahippocampal cortex, is in a privileged position to exert a major influence in working memory processing.

Thesis (Ph. D.)--Massachusetts Institute of Technology, Dept. of Brain and Cognitive Sciences, 2009.<br>This electronic version was submitted by the student author. The certified thesis is available in the Institute Archives and Special Collections.<br>Includes bibliographical references (p. 97-103).<br>It is the goal of this thesis to examine the frontal cortex-basal ganglia system during arbitrary visuomotor association learning, the forming of arbitrary links between visual stimuli and motor responses (e.g. red means stop), a fundamental learning process that underlies much of our complex behavior such as written language. The experiments contained in this thesis investigate the involvement of four components of this system in the acquisition of these associations: dorsolateral prefrontal cortex (dlPFC), caudate nucleus (Cd), frontal eye field (FEF), and the internal segment of the globus pallidus (GPi). Extracellular electrophysiological recordings were performed in awake-behaving primates performing three different learning tasks. In the different behavioral paradigms used in these studies, learning with and without reversals is investigated and compared both directly within the same experiment and indirectly across experiments. The results of these studies suggest that a complex interplay between brain areas in the frontal cortex-basal ganglia system exists. The study of FEF during reversal learning revealed that FEF contains task-related information from the start of learning, suggesting that it may be passing information onto PFC and Cd to aid the learning process. In addition, GPi is shown to contain more specific information about the learned association during the reversal task, providing evidence for an increase in the complexity of information processing through the basal ganglia.<br>(cont.) The in-depth study of dlPFC and Cd suggests that the frontal cortex-basal ganglia system functions only when competition between learning contexts exist. When all competition is eliminated by removing reversal learning from the behavioral task, Cd does not show involvement in the learning process. But when competition exists, both Cd and PFC show learning-related changes in task-relevant information. As determined by coherence analysis of local field potentials, communication between dlPFC and Cd is greater during reversal learning, when competition is heightened. This communication also decreases as learning progresses suggesting a role in the transfer of information between areas in facilitating the learning process. Overall, these studies further the understanding of the role of the frontal cortex-basal ganglia system in arbitrary visuomotor learning and posit that the function of the system is dependent on the existence of competition between learned information.<br>by Michelle S.

Abstract:
The reticular-activating hypofrontality model of acute exercise (RAH) predicts exercise-induced hypoactivity in frontal cortex which mediates executive function. Connors Continuous Performance Test (CCPT) was used to investigate changes in executive function during- and post treadmill running in healthy volunteers (n=30, 15 male). In a randomized order, subjects performed the CCPT at rest, during low- (LI; 63% maximal heart rate; MHR) and moderate intensity (MI; 75% MHR). Separately, subjects then performed isocalorifically matched exercise bouts of LI, MI and high intensity interval training (HIT) consisting of 4x4 min with 90% MHR and 3 min recovery at 60-70% MHR. Repeated measures ANOVAs revealed main effects of exercise intensity for reaction time RT during- (p≤0.001) and post exercise (p≤0.0001). Subsequent analyses showed an overall increase of RT during exercise compared to rest (p≤0.005). RT decreased significantly from rest to post exercise levels in an exercise intensity dependent, linear fashion (p≤0.0001). Commission errors showed a non significant linear trend to increase both during (p=0.057), and post exercise (p=0.052) as a function of intensity. In a follow up study, we sought to relate observed exercise effects to frontal cortex activity through the use of transcranial direct current stimulation (tDCS) (n=4) and transcranial magnetic stimulation (TMS) over the dorsolateral prefrontal cortex (DLPFC). Prior to TMS stimulation cortical excitability was estimated post running through motor-evoked potentials (MEP) elicited from the primary motor cortex (M1) induced by single burst TMS and measured in the first dorsal interosseous (FDI) muscle using electromyography. At rest, inhibitory cathodal tDCS with left DLPFC cathode and right supraorbital anode led to improved reaction time and increased amount of commission errors, whereas anodal stimulatory tDCS in the immediate post exercise period was unable to recover the post exercise effect. Continuous theta burst stimulation over the left DLPFC post running further impaired inhibitory control and facilitated reaction time. Different findings during- and after- exercise suggests that potential contributing mechanisms such as computational and metabolic factors may be differentially active during these respective conditions. Furthermore, the fact that an inhibitory TMS protocol pronounced the post running effects even more and that we were able to mimic the reported RAH effects at rest with inhibitory frontal tDCS, but observed different patterns during exercise, suggests that the latter state cannot be fully explained by reducing activity in the left frontal cortex alone. Failure to modify the after exercise effect with stimulatory tDCS also supports an interplay of different factors and might emphasize the strong, robust effects of exercise that cannot simply be attenuated by current application. Increases in MEP post running for 35min paired with the observed performance decrements imply an excited state of M1 and might serve as an explanatory cross-link to central fatigue suggesting that a hypofrontal state might enhance the motor cortical drive to activate muscles.

Abstract:
The primate prefrontal cortex sits at the top of the sensory, motor, and outcome processing hierarchies of the neocortex. It transforms sensory inputs into motor outputs, determining the response that is appropriate given the current context and desired outcome. This transformation involves conditional rules. The dorsal prefrontal cortex supports the learning of behavioural sequences, where the next action is conditional on the previous one. The ventral prefrontal cortex supports associations between objects, where the choice of one object is conditional on the presence of another object. However, because hierarchical processing supports the extraction of abstract representations, the primate prefrontal cortex is able to represent conditional rules that are abstract, meaning that they apply irrespective of the specific inputs. The selective advantage is that by learning these rules, primates can solve new problems rapidly when they have the same conditional logic as prior problems. The human prefrontal cortex has the same fundamental organization as in other primates. The dorsal prefrontal cortex supports the understanding of sequences and the ventral prefrontal cortex supports the ability to learn semantic associations. Thus the human prefrontal cortex has co-opted and elaborated mechanisms that were present in ancestral primates. These mechanisms can be used for new ends. For example, words have been associated with objects so as to communicate with others. This means that to understand human intelligence it is necessary to take into account the fact that the abstract rules are transmitted verbally from one generation to another.

Abstract:
Higher cognitive disorders involve insults to the neural circuits of the newly evolved association cortices. Although these cortices comprise the majority of the human cortex, little is understood about their molecular modulation. Research on the primate dorsolateral prefrontal cortex (dlPFC) indicates that the newly evolved layer III circuits underlying mental representation are regulated at the molecular level in a manner that is fundamentally different from classic synapses. These mechanisms must be respected to create effective treatments for human disorders, where a major goal is to optimize the network connectivity needed for persistent and precise neural representations. Understanding the needs of dlPFC circuits has led to the successful translation of guanfacine (Intuniv) for treating cognitive disorders, supporting this research strategy.

Abstract:
To survive, let alone flourish, we need to be sure of—securely tied to—at least one other person. We also need to be sure of our general acceptance within the wider social world. This book explores the normative implications of taking our social needs seriously. Chapter 1 sketches out what our core social needs are, and Chapter 2 shows that they ground a fundamental, but largely neglected human right against social deprivation. Chapter 3 then argues that this human right includes a right to sustain the people we care about, and that often, when we are denied the resources to sustain others, we endure social contribution injustice. Chapters 4–6 explore the tension between our needs for social inclusion and our needs for interactional and associational freedom, showing that social inclusion must take priority. While Chapters 5 and 6 defend a narrow account of freedom of association, Chapter 7 shows that the moral ballgame changes once we have made morally messy associative decisions. Sometimes we have rights to remain in associations that we had no right to form. Finally, Chapter 8 exposes the distinct social injustices that we do to people whom we deem to be socially threatening. Overall, the book identifies ways to change our social and political practices, and our personal perspectives, to better honour the fact that we are fundamentally social beings.

Abstract:
We are surrounded by digital computers. They do many things well that humans do not and have transformed our lives. But all computers are not the same. Although digital computers dominate today’s world, alternative ways to “compute” might be better and more efficient than digital computation when mechanically performing those tasks, important to humans, that we think of as “cognition.” Cognition, after all, was originally developed to work with our own specific biological hardware. Digital computers require elaborate detailed instructions to work; they are flexible but not simple. Analog computers are designed to do specific tasks. They can be simple but not flexible. Hardware matters. The book discusses two classic kinds of computer, digital and analog, and gives examples of their history, functions, and limitations. The author suggest that when brain “hardware,” with its associated brain “software” work together, it could form a computer architecture that would be useful for the efficient performance of cognitive tasks. This book discusses the essentials of brain hardware—in particular, the cerebral cortex, where cognition lives—and how cortical structure can influence the form taken by the computational operations underlying cognition. Topics include association, understanding complex systems through analogy, formation of abstractions, and the biology of number and its use in arithmetic and mathematics. The author introduces novel “brain-like” control mechanisms: active associative search and traveling waves. There is discussion on computing across scales of organization from single neurons to brain regions containing millions of neurons.

Abstract:
The amygdaloid complex located within the medial temporal lobe plays an important role in the acquisition and expression of learned fear associations (Quirk et al. 2003) and contains three main components: the lateral nucleus (LA), the basal nucleus (BLA), and the central nucleus (CE) (Faber and Sah, 2002). The lateral nucleus of the amygdala (LA) is widely accepted to be a key site of plastic synaptic events that contributes to fear learning (Pare, Quirk, LeDoux, 2004). There are two main types of neurons within the LA and the BLA: principal pyramidal-like cells which form projection neurons and are glutamatergic and local circuit GABAergic interneurons (Faber and Sah, 2002). In auditory fear conditioning, convergence of tone [conditioned stimulus (CS)] and foot-shock [unconditioned stimulus (US)] inputs potentiates the synaptic transmission containing CS information from the thalamus and cortex to LA, which leads to larger responses in LA in the presentation of subsequent tones only. The increasing LA responses disinhibit the CE neurons via the intercalated (ITC) cells, eliciting fear responses via excessive projections to brain stem and hypothalamic sites (Pare, Quirk, LeDoux, 2004). As a result, rats learn to freeze to a tone that predicts a foot-shock. Once acquired, conditioned fear associations are not always expressed and repeated presentation of the tone CS in the absence of US causes conditioned fear responses to rapidly diminish, a phenomenon termed fear extinction (Quirk et al. 2003). Extinction does not erase the CS-US association, instead it forms a new memory that inhibits conditioned response (Quirk et al. 2003)

Abstract:
Impaired working memory and anxiety are major clinical symptoms commonly associated with subjects exposed to blast overpressure [1–4]. Despite this association, there remains a vital need for biomarkers to help effectively diagnosis blast-induced neurotrauma (BINT). Clinically, elevated myo-inositol has been associated with several neurodegenerative disorders including dementia and elevated levels may reflect activation of microglia. In the present study, we evaluated the cognitive and behavioral changes in blast exposed animals using the novel object recognition (working memory paradigm) and light/dark (anxiety test) assessments. In addition, we used high resolution magic angle spinning H-MRS to assess neurochemical changes in the prefrontal cortex and amygdala, brain regions associated with working memory and anxiety respectively. Results suggest that exposure to blast has a significant effect on the levels of myo-inositol which appear to be linked with impaired working memory.

Abstract:
The Upper Cibulakan Formation is one of the main reservoirs in the Offshore North West Java Basin. It was deposited in a shallow marine environment with Tidal Shelf Ridge morphology. Sedimentology and seismic approaches are integrated in this study to understand lithofacies, depositional stages and morphological patterns of Tidal Shelf Ridge. The study is restricted to Zone 29, P-Field with available data being 5 wells data that have cores, 64 well data, and 3D seismic data. The lithofacies data of these wells is integrated with log data using a Multi Resolution Graph-based Clustering (MRGC) method to predict the lithofacies and depositional stage of other wells without core. There are 10 different lithofacies and 4 facies association identified from these well cores. Facies associations that were found refer to nomenclature of depositional stage of Tidal Shelf Ridge. The embryonic stage consists of claystone-siltstone or calcareous highly-cemented sandstone (with erosional contact), which is the stage of beginning of deposition of the shelf ridge. The immature accretion stage consists of siltstone and sandstone with an intense heterolithic structure. The mature accretion stage consists of sandstone with little or no appearance of heterollitic structure. The abandonment stage is the final stage of shelf ridge that consist of calcareous highly-cemented sandstone without erosional contact. Stratigraphic pattern based on vertical order of facies association is showing 5 transgressive parasequence tracts bounded by 6 flooding surface markers. Based on seismic attributes, which is an average of amplitude x thickness in parasequence, the pattern and morphology of tidal shelf ridge body is relatively northeast – southwest direction. The results of this study are expected to be a reference in developing more advanced hydrocarbon production by understanding of the morphology of reservoir body.

Abstract:
The cyclic loading encountered due to exposure to whole body vibration has been implicated as a risk factor for occupational low back disorders (OLBD, Wilder, 1996). The frequent bending and lifting has been identified as a major risk for acute disc prolapse. Wilder (1985) has shown that cyclic loading causes a decline in the stiffness properties of the motion segments and predisposes them to more risk of buckling injury. Numerous studies have also demonstrated that soft tissues subjected to repetitive loading show creep and stress relaxation behavior because of their viscoelastic properties. The cumulative trauma and residual strain in the soft tissues due to repetitive loading may predispose the motion segment to altered load distribution—hence accelerating the process of disc degeneration. Although the association of load and risk of OLBD has been established, the nature of dose-response is less than clear. The current study developed a unique apparatus using an in vitro porcine spine model to quantify the alteration in the load response under cyclic compression loading at different loading conditions. The purpose of current project is to understand the mechanical gross response of the spinal motion segment during repetitive loading. The porcine spine motion segments were used in the study. Two group of loading condition were applied; one is the compression force evenly distributed on the top of vertebrae, and one is compression force at the anterior cortex of vertebrae. Both loading conditions were loaded for 90,000 cycles at 5 Hz. The total loading period is 5 hours. The loading was set at 200 N compression and 50 N tension from peak to peak. The results showed the spine is not stabilized even after 90,000 cycles of loading, and the evenly distributed loading condition obtained higher deformation than the anterior flexed loading condition.
