Collinear contextual suppression
نویسندگان
چکیده
The context of a target can modulate behavioral as well as neural responses to that target. For example, target processing can be suppressed by iso-oriented surrounds whereas it can be facilitated by collinear contextual elements. Here, we present experiments in which collinear elements exert strong suppression whereas iso-oriented contextual surrounds yield no contextual modulation--contrary to most studies in this field. We suggest that contextual suppression depends strongly on the spatial arrangement of the context pointing to the influence of Gestalt factors in contextual modulation.

Optical Imaging of Contextual Interactions in V1 of the 1 Behaving Monkey
24 Interactions in primary visual cortex (V1) between simple visual elements such as short bar 25 segments are believed to underlie our ability to easily integrate contours and segment 26 surfaces. We used intrinsic signal optical imaging in alert fixating macaques to measure the 27 strength and cortical distribution of V1 interactions amongst collinear bars. A single short 28 bar stimulus prod...

A vertical bar is salient among horizontal ones by orientation contrast, and, traditionally, bottom up salience is viewed as caused only by feature contrast. Recently, it has been proposed that the primary visual cortex (V1) creates a bottom-up salience map in its outputs, which depends on direct inputs and on contextual inputs by intra-cortical interactions (Li Zhaoping, 2002 Trends in Cogniti...

متن کاملSuppressive lateral interactions at parafoveal representations in primary visual cortex.
The perceptual salience and visibility of image elements is influenced by other elements in their vicinity. The perceptual effect of image elements on an adjacent target element depends on their relative orientation. Collinear flanking elements usually improve sensitivity for the target element, whereas orthogonal elements have a weaker effect. It is believed that the collinear flankers exert t...
متن کاملCollinear facilitation and suppression at the periphery
Collinear facilitation is a common phenomenon in the fovea, but it has been recently challenged at the human periphery. Since physiological studies show that facilitation is found at the periphery but only from outside the receptive field, our hypothesis was that facilitation at the periphery exists but from larger target-flanker separations than the fovea. Here, we applied a recent paradigm (P...
