When adapted to a particular scenery our senses may fool us: colors are misinterpreted,
certain spatial patterns seem to fade out, and static objects appear to move in reverse. A …

A key hypothesis in sensory system neuroscience is that sensory representations are
adapted to the statistical regularities in sensory signals and thereby incorporate knowledge …

Psychophysical approaches that allow us to estimate how perceived stimulus intensity is
linked to physical intensity are import tools for studying nonlinear transformations of visual …

To model the responses of neurons in the early visual system, at least three basic
components are required: a receptive field, a normalization term, and a specification of …

Understanding the functional role of neurons and neural systems is a primary goal of
systems neuroscience. A longstanding hypothesis states that sensory systems are matched …

The purpose of this article is to provide mathematical insights into the results of some Monte
Carlo simulations published by Tolhurst and colleagues (Clatworthy, Chirimuuta, Lauritzen …

We are studying how people perceive naturalistic suprathreshold changes in the colour,
size, shape or location of items in images of natural scenes, using magnitude estimation …

The visual system employs a gain control mechanism in the cortical coding of contrast
whereby the response of each cell is normalised by the integrated activity of neighbouring …

In a wide variety of neural systems, neurons tuned to a primary dimension of interest often
have responses that are modulated in a multiplicative manner by other features such as …

The efficient coding hypothesis posits that sensory systems are adapted to the regularities of
their signal input so as to reduce redundancy in the resulting representations. It is therefore …
