Updating of visual space across horizontal saccades in cerebellar and thalamic lesion patients.

Efference copies of motor commands are used to update visual space across saccades, ultimately ensuring transsaccadic constancy of space. Thalamic lesions have been shown to impair efference copy-based saccadic updating in an oculomotor context, i.e., when two successive saccades are required. Moreo

Systematic biases in adult color perception persist despite lifelong information sufficient to calibrate them.

Bompas A, Powell G, Sumner P.SourceCUBRIC - School of Psychology, Cardiff University, Cardiff, Wales, UK.
Journal of vision.J Vis.2013 Jan 16;13(1). pii: 19. doi: 10.1167/13.1.19.
Learning from visual experience is crucial for perceptual development. One crucial question is when this learning occurs and to what extent it compensates for changes in the visual system throughout life. To address this question, it is essential to compare human performance not only to the hypothet

Gamut relativity: A new computational approach to brightness and lightness perception.

Vladusich T.SourceInstitute for Telecommunications Research, University of South Australia, Adelaide, Australia.
Journal of vision.J Vis.2013 Jan 9;13(1). pii: 14. doi: 10.1167/13.1.14.
This article deconstructs the conventional theory that "brightness" and "lightness" constitute perceptual dimensions corresponding to the physical dimensions of luminance and reflectance, and builds in its place the theory that brightness and lightness correspond to computationally defined "modes,"

The steady-state concept of Na(+) homeostasis, based on short-term investigations of responses to high salt intake, maintains that dietary Na(+) is rapidly eliminated into urine, thereby achieving constant total-body Na(+) and water content. We introduced the reverse experimental approach by fixing
