A central goal of neuroscience is to understand the representations formed by brain activity
patterns and their connection to behaviour. The classic approach is to investigate how …

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

Crowding, generally defined as the deleterious influence of nearby contours on visual
discrimination, is ubiquitous in spatial vision. Crowding impairs the ability to recognize …

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 …

Electrophysiological studies indicate that neurons in the middle temporal (MT) area of the
primate brain are selective for the velocity of visual stimuli. This paper describes a …

Recent research [Parkhurst, D., Law, K., & Niebur, E., 2002. Modeling the role of salience in
the allocation of overt visual attention. Vision Research 42 (1)(2002) 107–123] showed that …

We describe a form of nonlinear decomposition that is well-suited for efficient encoding of
natural signals. Signals are initially decomposed using a bank of linear filters. Each filter …

We can claim that we know what the visual system does once we can predict neural
responses to arbitrary stimuli, including those seen in nature. In the early visual system …

Responses of neurons that integrate multiple sensory inputs are traditionally characterized
in terms of a set of empirical principles. However, a simple computational framework that …

The origin of orientation selectivity in the responses of simple cells in cat visual cortex serves
as a model problem for understanding cortical circuitry and computation. The feed-forward …
