Abstract:

Precise point-to-point connectivity is the basis of ordered maps of the visual field in the brain. One point in the visual field is represented at one locus in the dLGN and one locus in primary visual cortex. A fundamental problem in the development of most sensory systems is the creation of the topographic projections which underlie these maps. Mechanisms ranging from ordered ingrowth of fibres, through chemical guidance of axons to sculpting of the map from an early exuberant input have been proposed. However, we know little about how ordered maps are created beyond the first relay. What we

The lateral geniculate nucleus (LGN) has been increasingly recognized to actively regulate information transmission to primary visual cortex (V1). Although efforts have been devoted to study its morphological and functional features, the full array of response characteristics in mouse LGN as well as their dependency on subjective state have been relatively unexplored. To address the question we recorded from mouse LGN with multisite-electrode-arrays (MEAs). From a dataset with 185 single units, our results revealed several exceptional response features in mouse LGN. We also demonstrated that s

The dLGN (dorsal Lateral Geniculate Nucleus) is the gateway to cortical processing for visual information encoded by RGCs (retinal ganglion cells). Owing to advances in genetic manipulations, the mouse is increasingly the model system of choice for understanding the function and organisation of the visual system. However the mouse dLGN has not been thoroughly investigated anatomically due to its difficult topology and location in the brain. We addressed this issue by indentifying the best reconstruction paradigm for recovering the true 3D shape of the dLGN from serial histological sections. We

Thalamic organization is highly conserved throughout species and the dLGN of the mouse possesses many features common to higher mammals, such as carnivores and primates. Two general classes of neuron are present within the dLGN, thalamocortical relay cells and interneurons, both of which

To investigate that matter, we proceeded to simultaneous recordings of the ERG and of single cell unit activity at the geniculate level in paralyzed and anesthetized rabbits. Our results show that 86.4% of the geniculate cells (n = 162) responded to the flash before the peak of the b-wave. One of the oscillatory potentials, the OP2, was preceding the geniculate activity in 77.8% of the cases. Furthermore, the shifts in la

Abstract:

The development of the diencephalon can be summarised as a process in which cells that initially appear similar give rise to a complex structure that contains a variety of cell groups called nuclei. It involves two stages: the early patterning of the diencephalic prosomeres and the later formation of the individual nuclei. It has been shown that transcription factors and morphogens regulate the first stage but their further effects on the second stage remain unclear. The ventral lateral geniculate nucleus (vLGN) is involved in the visual system and is shown to have complex origins from the tha

Retinogeniculate (RG) synapses connect retinal ganglion cells to the thalamic relay cells of the dorsal lateral geniculate nucleus (dLGN). They are critical for regulating the flow of visual information from retina to primary visual cortex (V1). RG synapses in dLGN are uniquely larger and stronger than their counterparts in other retinorecipient regions. Moreover, in dLGN, RG synapses can be classified into two groups: simple RG synapses, which contain glia-encapsulated single RTs synapsing onto relay cell dendrites, and complex RG synapses, which contain numerous RTs that converge onto the s

BDNF is chemo-attractive for gustatory neurons and regulates gustatory neuron targeting and number during development. NT4 regulates gustatory neuron number earlier in development than BDNF, but it is not chemo-attractive and does not regulate gustatory neuron targeting. To elucidate the mechanisms that regulate these processes we have examined which TrkB intracellular signalling pathways are required for specific aspects of gustatory devel

Abstract:

The medial geniculate body (MGB) is the thalamic nucleus situated between the inferior colliculus (IC) and auditory cortex (AC) in the ascending auditory pathway. It has classically been thought of as a relay station for auditory stimuli; however, we now know that is capable of significantly influencing incoming auditory information. As aging occurs, there is a loss of auditory signal fidelity as well as a disruption in the accurate coding of acoustic information. In order to compensate for the age-related loss of auditory signal quality, additional cortical resources play a role in knowledge-

The auditory thalamus or medial geniculate body (MGB) is the final brain structure for acoustic information processing prior to, and functioning in reciprocity with, auditory cortex. MGB neurons process and gate aspects of acoustic stimuli, functions which depend partly on GABAergic inhibition. To characterize these properties, the inhibitory neurotransmitters involved and how they may be altered in the aged MGB, specific aims sought to: 1) determine the presence of functional high affinity GABAA receptors (GABAARs) in the MGB, 2) determine whether GABAAR function is altered with age and 3) de

Experimental and clinical data have documented the adverse effects of perinatal ethanol intoxication on peripheral organs and the central nervous system. There is little known, however, about potential damaging effects of perinatal ethanol on the developing visual system. The purpose of this study was to examine the effects of neonatal ethanol intoxication on RGC morphology, estimate the total number of neurons in RGC layer and dorsolateral geniculate nucleus (dLGN), and on the eye-specific fiber segregation in the dLGN), in YFP and C57BL/6 mice pups. Ethanol (3 g/kg/day) was administered by i

Abstract:

The dorsal lateral geniculate nucleus (dLGN) has become an important model for studying many aspects of visual system development. To date, studies have focused on the development of retinal projections and the role of activity in shaping the pattern of synaptic connections made with thalamocortical relay cells. By contrast, little is known about relay cells and the factors that regulate the growth and establishment of their dendritic architecture. In many systems, such growth seems consistent with the synaptotrophic hypothesis which states that synapse formation and dendritic growth work in

Abstract:

Vision provides a critical interface with the physical world. This work examines visual development and vision loss in mice to glean the influence of the retinal state on visual connections. I first assessed the impact of retinal activity on the eye-specific segregation of retinal afferents in the lateral geniculate nucleus (LGN) of young Gβ5 -/- mice. Gβ5 is the fifth member of the β subfamily of heterotrimeric G proteins. Gβ5 binds and stabilizes the R7 family of regulators of G-protein signaling (RGS), which accelerate Gi/o GTP hydrolysis. Gβ5 -/- mice, which lack R7RGS activity, have malfo

Abstract:

O estudo da acuidade Vernier (VRN) revela a capacidade do sistema visual humano em detectar deslocamentos espaciais de poucos arcos de segundos, menores que a distância entre dois cones foveais adjacentes. Tal fato desperta interesse teórico sobre o tema, além de futuras aplicações na área clínica. A acuidade VRN pode ser medida tanto psicofisicamente quanto eletrofisiologicamente. Para a detecção de quebras de colinearidade (acuidade VRN), alguns autores hipotetizam que as células ganglionares (CGs) M da retina provêem sinal adequado da retina ao córtex, e dão suporte ao desempenho psicofísic

Abstract:

In the developing visual system, the axon of a pre-synaptic cell must be guided to a post-synaptic partner. Retinal ganglion cells (RGCs) in the eye are an excellent model to study this process. Multiple classes exist that respond to specific types of light input, and these project to different destinations in the brain that process distinct types of information. The RGC axons that navigate to the lateral geniculate nucleus (LGN) do so in a class-specific manner. Axons from RGCs that mediate non-image forming functions innervate the ventral LGN (vLGN) and the intergeniculate leaflet (IGL). Ax

Abstract:

The primate visual system is organised and wired in a topological manner. From the eye well into extrastriate visual cortex, a preserved spatial representation of the vi- sual world is maintained across many levels of processing. Diffusion-weighted imaging (DWI), together with probabilistic tractography, is a non-invasive technique for map- ping connectivity within the brain. In this thesis I probed the sensitivity and accuracy of DWI and probabilistic tractography by quantifying its capacity to detect topolog- ical connectivity in the post mortem macaque brain, between the lateral geniculate
