Correlated activity of lateral geniculate neurones in binocularly deprived cats.
Pairs of single neurones were recorded simultaneously from lateral geniculate nucleus of adult cats binocularly deprived of pattern vision by rearing in masks. Receptive fields of cells in laminae A and A1 were highly abnormal with unusually small proportion of Y-type fields and some neurones characterized by ON/OFF type of responses. In spite of these changes all crosscorrelogram patterns betw...
متن کاملPassive cable properties and morphological correlates of neurones in the lateral geniculate nucleus of the cat.
1. We used an in vivo preparation of the cat to study the passive cable properties of sixteen X and twelve Y cells in the lateral geniculate nucleus. Cells were modelled as equivalent cylinders according to Rall's formulations (Rall, 1959a, 1969, 1977). We injected intracellular current pulses into these geniculate neurones, and we analysed the resulting voltage transients to obtain the cable p...
متن کاملIntegrative action in the cat's lateral geniculate body.
It has often been asked whether the lateral geniculate body contributes to the integration of incoming visual impulses or is a mere 'way-station' in the pathway from retina to cortex. While perhaps less complex than the retina or cortex, the geniculate is histologically far from the simple structure that the term 'way-station' would imply (O'Leary, 1940; Glees, 1941). The presence of extensive ...
متن کاملThe lateral geniculate nucleus
The lateral geniculate nucleus (LGN) is a huge embarrassment to visual neuroscientists. Virtually all the visual information that leaves the retina to be analysed in the visual cortex is relayed through synapses in this nucleus. It is a dogma of neurophysiology that the cost imposed by putting a synapse in any pathway must be repaid by some benefit in terms of processing. Unfortunately it is no...
متن کاملDistinct roles of metabotropic glutamate receptor activation on inhibitory signaling in the ventral lateral geniculate nucleus.
The ventral lateral geniculate nucleus (vLGN) has been implicated in numerous functions including circadian rhythms, brightness discrimination, pupillary light reflex, and other visuomotor functions. The contribution of inhibitory mechanisms in the regulation of vLGN neuron excitability remains unexplored. We examined the actions of metabotropic glutamate receptor (mGluR) activation on the intr...
