1. The visual cortex receives several types of afferents from the lateral geniculate nucleus
(LGN) of the thalamus. In the cat, previous work studied the ON/OFF and X/Y distinctions …

Providing the critical link between the retina and visual cortex, the well-studied lateral
geniculate nucleus (LGN) has stood out as a structure in search of a function exceeding the …

Simultaneous recording in the cat's retina and lateral geniculate nucleus (LGN) was used to
find excitatory inputs to LGN cells. These recordings, correlated with measurements of LGN …

The encoding of time-varying stimuli in linear and half-wave rectifying neurons is studied.
The information carried in single spike trains is assessed by reconstructing part of the …

The response of neurons in the primary visual cortex to an optimally oriented grating is
usually suppressed quite dramatically when a second grating of, for example, orthogonal …

A reverse correlation technique, which permits estimation of three-dimensional first-order
properties of receptive fields (RFs), was applied to simple cells in areas 17 and 18 of cat …

Previously, we proposed a model of the circuitry underlying simple-cell responses in cat
primary visual cortex (V1) layer 4. We argued that the ordered arrangement of lateral …

The use of fMRI and computational modeling has advanced understanding of spatial
characteristics of population receptive fields (pRFs) in human visual cortex. However, we …

We extend previous models for separate development of ocular dominance and orientation
selectivity in cortical layer 4 by exploring conditions permitting combined organization of …

We have designed and tested a single-chip analog VLSI sensor that detects imminent
collisions by measuring radially expanding optic flow. The design of the chip is based on a …
