Jan 14, 2021 · The visual system comprises the sensory organ (the eye) and parts of the central nervous system (the retina containing photoreceptor cells, the optic nerve, the optic tract and the visual cortex) which gives organisms the sense of sight (the ability to detect and process visible light) as well as enabling the formation of several non-image photo response functions.

Jan 19, 2021 · The visual system is the part of the nervous system which allows organisms to see. It interprets the information from visible light to build a representation of the world surrounding the body. The visual system has the complex task of (re)constructing a three dimensional world from a two dimensional projection of that world.
Jan 10, 2021 · In the visual system, receptive fields are volumes in visual space. They are smallest in the fovea where they can be a few minutes of arc like a dot on this page, to the whole page. For example, the receptive field of a single photoreceptor is a cone-shaped volume comprising all the visual directions in which light will alter the firing of that ...
Jan 01, 2021 · While the neural processing of the visual system is complex and has been modelled in great detail (Watson and Ahumada, 2005, Watson and Ahumada, 2008), the conceptually simpler measurement of neural contrast sensitivity has been a common summative functional measure of visual neural processing and captures beneficial behavioral effects such as ...

Jan 07, 2021 · The bottom-up contribution to the allocation of exogenous attention is a saliency map. However, how the saliency map is distributed when multiple salient stimuli are presented simultaneously and how this distribution interacts with awareness remain unclear. These questions were addressed here using visible and invisible stimuli that consisting of two salient foregrounds: the high one served as ...
