Research project

The Effect of Texture in Surround Suppression

Abstract: Surround suppression is when the firing rate of neurons in the primary visual cortex of the brain are modified because of surrounding stimulus outside of the neuron's receptive field. It is known that surround suppression can be demonstrated using sine-wave grating stimulus in a two-alternative forced choice (2AFC) task. Coen-Cagli, Kohn, & Schwartz, 2015 showed that flexible gain control, surround suppression, is present in everyday settings by using natural texture images. Our objective was to determine under what conditions of natural texture images is surround suppression produced and the degree to which it is produced.
