The role of primary visual cortex (V1) in visual awareness
In the search for the neural correlate of visual awareness, much controversy exists about the role of primary visual cortex. Here, the neurophysiological data from V1 recordings in awake monkeys are examined in light of two general classes of models of visual awareness. In the first model type, visual awareness is seen as being mediated either by a particular set of areas or pathways, or altern...
متن کاملDevelopment of Maps of Simple and Complex Cells in the Primary Visual Cortex
Hubel and Wiesel (1962) classified primary visual cortex (V1) neurons as either simple, with responses modulated by the spatial phase of a sine grating, or complex, i.e., largely phase invariant. Much progress has been made in understanding how simple-cells develop, and there are now detailed computational models establishing how they can form topographic maps ordered by orientation preference....
متن کاملRules of connectivity between geniculate cells and simple cells in cat primary visual cortex.
Hundreds of thalamic axons ramify within a column of cat visual cortex; yet each layer 4 neuron receives input from only a fraction of them. We have examined the specificity of these connections by recording simultaneously from layer 4 simple cells and cells in the lateral geniculate nucleus with spatially overlapping receptive fields (n = 221 cell pairs). Because of the precise retinotopic org...
متن کاملSelective effects of aging on simple and complex cells in primary visual cortex of rhesus monkeys.
The visual system is hierarchically organized between and within areas. Previous studies have found that aging affects different visual areas in a progressive manner, e.g. more degradation occurs in the primary visual cortex (V1) than in the dorsal lateral geniculate nucleus (dLGN), and more in the secondary visual (V2) and middle temporal (MT) visual areas than in V1. In view of these findings...
متن کاملSynaptic Basis for Differential Orientation Selectivity between Complex and Simple Cells in Mouse Visual Cortex.
UNLABELLED In the primary visual cortex (V1), orientation-selective neurons can be categorized into simple and complex cells primarily based on their receptive field (RF) structures. In mouse V1, although previous studies have examined the excitatory/inhibitory interplay underlying orientation selectivity (OS) of simple cells, the synaptic bases for that of complex cells have remained obscure. ...
