Of the many possible functions of the macaque monkey primary visual cortex (striate cortex,
area 17) two are now fairly well understood. First, the incoming information from the lateral …

This volume presents an integrated view of how we perceive the spatial relations in our
visual world, covering anatomical, physiological, psychophysical, and perceptual aspects …

Simple cells in the striate cortex have been depicted as half-wave-rectified linear operators.
Complex cells have been depicted as energy mechanisms, constructed from the squared …

Attention has been found to have a wide variety of effects on the responses of neurons in
visual cortex. We describe a model of attention that exhibits each of these different forms of …

▪ Abstract Single-unit recording studies in the macaque have carefully documented the
modulatory effects of attention on the response properties of visual cortical neurons …

Human observers fixated the center of a search array and were required to discriminate the
color of an odd target if it was present. The array consisted of horizontal or vertical black or …

The response of cortical neurons to a sensory stimulus is modulated by the context. In the
visual cortex, for example, stimulation of a pyramidal cell's receptive-field surround can …

Discusses the historical development of the evidence of response selectivity for visual
stimuli presented beyond the classical receptive fields (CRFs), examines the anatomical …

Texture features that are based on the local power spectrum obtained by a bank of Gabor
filters are compared. The features differ in the type of nonlinear post-processing which is …

Simple cells in the primary visual cortex often appear to compute a weighted sum of the light
intensity distribution of the visual stimuli that fall on their receptive fields. A linear model of …
