Recent experimental and theoretical results in cat primary visual cortex and in the whisker-
barrel fields of rodent primary somatosensory cortex suggest common organizing principles …

This comprehensively updated and expanded revision of the successful second edition
continues to provide detailed coverage of the ever-growing range of research topics in …

This paper reviews theoretical and experimental results on the processing of layer 4, the
input-recipient layer, of cat primary visual cortex (V1). A wide range of experimental data can …

Many phenomenological models of the responses of simple cells in primary visual cortex
have concluded that a cell's firing rate should be given by its input raised to a power greater …

Cortical neurons display two fundamental nonlinear response characteristics: contrast-set
gain control (also termed contrast normalization) and response expansion (also termed half …

One of the most salient features to emerge in visual cortex is sensitivity to stimulus
orientation. Here we asked if orientation selectivity, once established, is altered by …

The early stages of visual processing provide excellent models for the study of how
information is represented in, and processed by, the activity of neurons. The fact that the …

Humphrey, Allen L. and Alan B. Saul. Strobe rearing reduces direction selectivity in area 17
by altering spatiotemporal receptive-field structure. J. Neurophysiol. 80: 2991–3004, 1998 …

We used one-dimensional sparse noise stimuli to generate first-order spatiotemporal maps
and second-order two-bar interaction maps for 65 simple and 124 complex direction …

Cells in the superficial layers of primary visual cortex (area 17) are distinguished by
feedforward input from thalamic-recipient layers and by massive recurrent excitatory …
