Cortical-like receptive fields in the lateral geniculate nucleus of marmoset monkeys.
Most neurons in primary visual cortex (V1) exhibit high selectivity for the orientation of visual stimuli. In contrast, neurons in the main thalamic input to V1, the lateral geniculate nucleus (LGN), are considered to be only weakly orientation selective. Here we characterize a sparse population of cells in marmoset LGN that show orientation and spatial frequency selectivity as great as that of...
متن کاملSegregation of receptive field properties in the lateral geniculate nucleus of a New-World monkey, the marmoset Callithrix jacchus.
The lateral geniculate nucleus (LGN) in humans and Old-World monkeys is dominated by the representation of the fovea in the parvocellular (PC) layers, and most PC cells in the foveal representation have red-green cone opponent receptive field properties. It is not known whether these features are both unique to trichromatic primates. Here we measured receptive field properties and the visuotopi...
متن کاملLight level induced reorganization of cat's lateral geniculate nucleus receptive fields: a spatiotemporal study.
The spatiotemporal organization of receptive fields (RF) of the cats lateral geniculate cells was investigated under several scotopic and mesopic light adaptation levels, using stationary and moving light stimuli. A given adaptation level was reached by changing of either the diffuse background or the adapting central spot intensity. Both methods gave the same qualitative results. The RFs were...
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 کاملReceptive field dimensions of lateral geniculate cells in the common marmoset (Callithrix jacchus)
We measured the spatial receptive field dimensions of cells in the lateral geniculate nucleus (LGN) of the common marmoset (Callithrix jacchus) using a bipartite field stimulus in which the two halves of the field were modulated identically but in counterphase. Horizontal and vertical edges between the two fields were positioned at different locations in the receptive field. By assuming that ce...
