Effects of Visual Deprivation on Morphology and Physiology of Cells in the Cats Lateral Geniculate Body.
THEIMPORTANCEOFNORMALSENSORYSTIMULATION inthedevelopment and maintenance of the nervous system is now generally recognized. In the visual system this problem has usually been approached by examining the effects of sensory deprivation on structure and behavior (see reviews by Hebb (12) and Riesen (28)). An obvious way of extending this work would be to examine electrophysiologically the function...
متن کاملVisual field defects in vascular lesions of the lateral geniculate body.
Corresponding retinal nerve fibres begin their path in the eyes and end in a single visual cortical cell. Because of this arrangement, lesions in the anterior visual pathway produce incongruent visual field defects and in the posterior pathway congruent field defects. The lateral geniculate body is on the anterior third of the visual pathway. A lesion of this nucleus produces moderately to comp...
متن کاملLateral Geniculate Body Evoked Potentials Elicited by Visual and Electrical Stimulation
PURPOSE Blind individuals who have photoreceptor loss are known to perceive phosphenes with electrical stimulation of their remaining retinal ganglion cells. We proposed that implantable lateral geniculate body (LGB) stimulus electrode arrays could be used to generate phosphene vision. We attempted to refine the basic reference of the electrical evoked potentials (EEPs) elicited by microelectri...
متن کاملDiverse visual features encoded in mouse lateral geniculate nucleus.
The thalamus is crucial in determining the sensory information conveyed to cortex. In the visual system, the thalamic lateral geniculate nucleus (LGN) is generally thought to encode simple center-surround receptive fields, which are combined into more sophisticated features in cortex, such as orientation and direction selectivity. However, recent evidence suggests that a more diverse set of ret...
متن کاملCortically induced presynaptic inhibition in cat's lateral geniculate body.
The effect of cortical stimulation on the evoked response of the lateral geniculate body (LGB) was studied in the cat locally anesthetized and immobilized with Flaxedil. The evoked response of the LGB induced by single shock stimula tion of the optic tract consisted of pre and postsynaptic components. When single shock stimulation was applied to the visual cortex 50 100 msec prior to optic trac...
