Abstract:
Background: Resting state functional MRI (rs-fMRI) provides many advantages to task-based fMRI in neurosurgical populations, foremost of which is the lack of the need to perform a task. Many networks can be identified by rs-fMRI in a single period of scanning. Despite the advantages, there is a paucity of literature on rs-fMRI in neurosurgical populations. Methods: Eight patients with tumours near areas traditionally considered as eloquent cortex participated in a five minute rs-fMRI scan. Resting-state fMRI data underwent Independent Component Analysis (ICA) using the Multivariate Exploratory

Abstract:
Abstract Despite the abundance of behavioral evidence showing the interaction between attention and prediction in infants, the neural underpinnings of this interaction are not yet well understood. The endogenous attentional function in adults have been largely localized to the frontoparietal network. However, resting-state and neuroanatomical investigations have found that this frontoparietal network exhibits a protracted developmental trajectory and involves weak and unmyelinated long-range connections early in infancy. Can this developmentally nascent network still be modulated by prediction

Abstract:
Relations between spatial attention and motor intention were investigated by means of an EEG potential elicited by shifting attention to a location in space as well as by the selection of a hand for responding. High-density recordings traced this potential to a common frontoparietal network activated by attentional orienting and by response selection. Within this network, parietal and frontal cortex were activated sequentially, followed by an anterior-to-posterior migration of activity culminating in the lateral occipital cortex. Based on temporal and polarity information provided by EEG, we h

AbstractThe frontoparietal control network, anatomically and functionally interposed between the dorsal attention network and default mode network, underpins executive control functions. Individuals with attention-deficit/hyperactivity disorder (ADHD) commonly exhibit deficits in executive functions, which are mainly mediated by the frontoparietal control network. Involvement of the frontoparietal control network based on the anterior prefrontal cortex in neurobiological mechanisms of ADHD has yet to be tested.

Human behavior involves monitoring and adjusting performance to meet established goals. Performance-monitoring systems that act by detecting conflict in stimulus and response processing have been hypothesized to influence cortical control systems to adjust and improve performance.

We tested the hypothesis that the ACC would be sensitive to conflict during attentional orienting and influence activity in the frontoparietal attentional control network that selectively m

Abstract:
The cortical dorsal attention network (DAN) is a set of parietal and frontal regions that support a wide variety of attentionally demanding tasks. Whereas attentional deployment reliably drives DAN activity across subjects, there is a large degree of variation in the activation pattern in individual subjects. We hypothesize that a subject’s own idiosyncratic pattern of cortical DAN activity can be predicted from that subject’s own unique pattern of functional connectivity. By modeling task activation as a function of whole brain connectivity patterns, we are able to define the connectivity fin

Abstract Priming of attention shifts involves the reduction in search RTs that occurs when target location or target features repeat. We used functional magnetic resonance imaging to investigate the neural basis of such attentional priming, specifically focusing on its temporal characteristics over trial sequences. We first replicated earlier findings by showing that repetition of target color and of target location from the immediately preceding trial both result in reduced blood oxygen level-dependent (BOLD) signals in a cortical network that encompasses occipital, parietal, and frontal cort

Mind wandering represents the human capacity for internally focused thought and relies upon the brain’s default network and its interactions with attentional networks. Studies have characterized mind wandering in healthy people, yet there is limited understanding of how this capacity is affected in clinical populations. This paper used a validated thought-sampling task to probe mind wandering capacity in two neurodegenerative disorders: behavioral variant frontotemporal dementia [(bvFTD); n = 35] and Alzheimer’s disease [(AD); n = 24], compared with older controls (n = 37).

Any natural visual environment contains a huge collection of objects, which impact on our perception and compete for drawing our interest and therefore for being preferentially noticed. By effectively selecting a relevant fraction of the incoming information for further in-depth processing, visual selective attention (VSA) optimizes vision in order to overcome the intrinsically limited computational capacity of the visual system.

Abstract:
Attention, working memory, decision-making, and executive control are fundamental cognitive functions that involve large-scale networks largely defined on the basis of functional magnetic resonance imaging (fMRI) studies. These networks include areas of the lateral and medial prefrontal, orbitofrontal, anterior, and midcingulate cortices, anterior insula, and lateral and medial posterior parietal cortices as well as areas of the temporal lobe and temporoparietal junction. These networks include the dorsal and ventral attention networks, frontoparietal, cingulo-opercular and salience control networks, and the default mode network. These networks are located along a hierarchical gradient of cortical organization. Dysfunction of large-scale cortical networks is a cardinal feature of neurodegenerative dementias and psychiatric disorders.

Abstract:
This chapter addresses functional magnetic resonance imaging (fMRI) of brain in children with neurodevelopmental and behavioral disorders. Common challenges of pediatric fMRI studies are related to acquisition and processing. In children with disruptive behavior disorders, deficits in affective response, empathy, and decision-making have been reported. Resting-state fMRI studies in attention-deficit hyperactivity disorder (ADHD) have shown altered activity in default mode and cognitive control networks. Task-based fMRI studies in ADHD have implicated frontoparietal cognitive and attentional networks. The role of stimulants in restoring the altered brain function has been examined using fMRI studies. In children with autism spectrum disorder, fMRI studies using face-processing tasks, theory-of-mind tasks, imitation, and language processing (e.g., sentence comprehension), as well as studies of gaze aversion, interest in social faces, and faces with emotions have implicated cerebellum, amygdala, hippocampus, insula, fusiform gyrus, superior temporal sulcus, planum temporale, inferior frontal gyrus, basal ganglia, thalamus, cingulate cortex, corpus callosum, and brainstem. In addition, fMRI has been a valuable research tool for understanding neurobiological substrates in children with psychiatric disorders (e.g., psychosis, posttraumatic stress disorder, and anxiety disorders).

Abstract:
Abstract Chapter 5 is about planning and preparation as it relates to Intentional Change Theory (ICT). The third phase of ICT is articulation of a learning agenda and plan to use one’s strengths to move closer to the Ideal Self while possibly working on developing one to two weaknesses. It is a joyful exploration of possibilities. For most people, setting specific goals prematurely limits options, but later in the change process specific goals can help focus attention toward the new thoughts or behavior. The frontoparietal control network (FPCN) is key to instrumental thinking during goal setting. When the Task Positive Network is activated along with the FPCN, the Default Mode Network is suppressed. Specific goals can also cause a person to focus on the wrong things. The Ought Self invokes the Negative Emotional Attractor and further inhibits sustained effort, and also moves the person away from their own desires. When the challenge is not routine or task defined, learning-oriented goals, a growth mindset, and promotion self-regulatory focus help sustained, desired change. People with a relatively high Need for Achievement like specific goals. For most people, domain and direction planning may be a more effective form of planning.

Abstract:
Abstract Most concepts of goal-directed behavior and cognition emphasize cortico-cortical interactions within large-scale networks. However, many, if not all, direct connections between cortical areas are paralleled by a trans-thalamic cortico-pulvino-cortical route, whose importance has been demonstrated by electrophysiological and lesion studies in monkeys and humans. In most literature, the pulvinar is conceived as a “visual” thalamic nucleus, with proven contributions to higher-order visual functions related to visual attention, feature binding, and processing of emotional stimuli. At the same time, the expansion of its dorsal portion in primates, in particular in humans, and its anatomical connectivity with frontoparietal regions suggests an important role in higher-order motor functions such as eye-hand coordination and manual prehension. In this chapter, the authors review electrophysiological, imaging, lesion, and human patient studies showing that pulvinar function goes well beyond its subscribed role in visual attention and might be more appropriately conceived as a multimodal integrator underlying visually guided saccades and reach-grasp behavior. A specific focus will lie on lesion-induced visuospatial and reach-grasp deficits in monkeys and humans.
