Cholinergic enhancement reduces orientation-specific surround suppression but not visual crowding
Acetylcholine (ACh) reduces the spatial spread of excitatory fMRI responses in early visual cortex and the receptive field sizes of V1 neurons. We investigated the perceptual consequences of these physiological effects of ACh with surround suppression and crowding, two tasks that involve spatial int...
