The retino-geniculo-cortical pathways of the cat composed of at least three parallel channels. The neurons in these channels (W-, X-, and Y-cells) have different physiological properties. In earlier studies, we used a direct structure-function for analysis for individual geniculate neurons in normal cats. This was accomplished by electrophysiological characterization of the neuron followed by i...
Brain-derived neurotrophic factor (BDNF) and neurotrophin-4 (NT-4) are two neurotrophins that play distinct roles in geniculate (taste) neuron survival, target innervation, and taste bud formation. These two neurotrophins both activate the tropomyosin-related kinase B (TrkB) receptor and the pan-neurotrophin receptor p75. Although the roles of these neurotrophins have been well studied, the deg...
Bell's palsy, which is defined as idiopathic peripheral facial paralysis of sudden onset, accounts for > 50% of all cases of facial paralysis. Different theories on the etiology of Bell's palsy have been proposed and investigated. Various clinical studies have suggested an etiological link between Bell's palsy and herpes simplex virus (HSV). In addition, animal experiments have shown the abilit...
Spontaneous activity patterns in the developing retina appear important for the functional organization of the visual system. We show here that an absence of early retinal waves in mice lacking the beta2 subunit of the nicotinic acetylcholine receptor (nAChR) is associated with both gain and loss of functional organization in the dorsal lateral geniculate nucleus (dLGN). Anatomical studies show...
A hallmark of mammalian neural circuit development is the refinement of initially imprecise connections by competitive activity-dependent processes. In the developing visual system retinal ganglion cell (RGC) axons from the two eyes undergo activity-dependent competition for territory in the dorsal lateral geniculate nucleus (dLGN). The direct contributions of synaptic transmission to this proc...
Along most neural pathways, the spike trains transmitted from one neuron to the next are altered. In the process, neurons can either achieve a more efficient stimulus representation, or extract some biologically important stimulus parameter, or succeed at both. We recorded the inputs from single retinal ganglion cells and the outputs from connected lateral geniculate neurons in the macaque to e...
The organization of geniculostriate projections in Tupaia was studied using three separate methods, anterograde transport from the lateral geniculate, retrograde transport from the striate cortex, and reconstruction of single geniculostriate axons. The results show that each layer of the lateral geniculate body has a unique pattern of projections to the striate cortex, and each pattern consists...
Histological effects of Monosodium glutamate (MSG) commonly used as food additive on one of the visual relay centres namely the lateral geniculate body (LGB) of adult Wistar rat was studied. The rats of both sexes (n=24), average weight of 185g were randomly assigned into two treatments (n=16) and control (n=8) groups. The rats in the treatment groups received 3g and 6g of MSG thoroughly mixed ...
