The emergence of gamma oscillations as a signature of gain control during context integration.
Joseph Emerson,Audrey Sederberg,Cheryl Olman · COSYNE 2022
Context integration is a fundamental feature of the human visual system contributing to basic visual processing routines such as contour integration, visual pop-out, and texture segmentation. Two perceptual hallmarks of context integration are orientation-dependent surround suppression (ODSS) and the orientation tilt illusion. In these contextual effects, either the magnitude (ODSS) or the orientation (tilt illusion) of a neural population vector code is shifted depending on the relative orientation of the spatial surround. Supported by past modeling studies, these perceptual effects have been
