Distinct patterns of surround modulation in V1 and hMT+
Er, Görkem; Pamir, Zahide; Boyacı, Hüseyin (Academic Press Inc., 2020)Modulation of a neuron’s responses by the stimuli presented outside of its classical receptive field is ubiquitous in the visual system. This “surround modulation” mechanism is believed to be critical for efficient processing ... -
The role of contrast and size in motion perception: behavioral and neuroimaging study of center-surround interactions in primary visual cortex (V1) and middle temporal area (MT+)
Er, Görkem (Bilkent University, 2018-09)Behavioral experiments have demonstrated that observers' ability to discriminate the drift direction of a grating improves as its size increases if the grating has a low contrast, and deteriorates if it has a high contrast ...
