Temporal Evolution of Pattern Disparity Processing in Humans

Temporal evolution of pattern disparity processing in humans.

Stereo matching, i.e., the matching by the visual system of corresponding parts of the images seen by the two eyes, is inherently a 2D problem. To gain insights into how this operation is carried out by the visual system, we measured, in human subjects, the reflexive vergence eye movements elicited by the sudden presentation of stereo plaids. We found compelling evidence that the 2D pattern dis...

Temporal pattern processing in songbirds.

Understanding how the brain perceives, organizes and uses patterned information is directly related to the neurobiology of language. Given the present limitations, such knowledge at the scale of neurons, neural circuits and neural populations can only come from non-human models, focusing on shared capacities that are relevant to language processing. Here we review recent advances in the behavio...

Temporal Pattern Processing

Architecture of binocular disparity processing in monkey inferior temporal cortex.

Neurons in the inferior temporal (IT) cortex respond not only to the shape, color or texture of objects, but to the horizontal positional disparity of visual features in the right and left retinal images. IT neurons with similar shape selectivity cluster in columns. In this study, we examined how IT neurons are spatially arranged in the IT according to their selectivity for binocular disparity....

Experimental approaches to temporal processing in humans

At the meeting I consider work that addresses the bases for human temporal processing using two approaches; functional imaging using PET and fMRI and psychophysical studies of neurological patients with central lesions. The discussion below is primarily concerned with recent fMRI data addressing mechanisms of temporal processing in the brainstem and cortex. The intention is to highlight areas o...
