Extrastriate activity reflects sensorimotor-induced bias in estimating number of visual humans.

ABSTRACT: Humans and animals are able to rapidly, and with reasonable accuracy, estimate the number of objects in a visual scene. Visual-evoked potential studies have described a sequence of functionally distinct stages associated with numerosity perception. Recently, a specialized cognitive-perceptual system for the numerosity estimation for human stimuli (NEH), distinct from that for non-social stimuli, was revealed using virtual reality, revealing a stable NEH overestimation bias (ie perceiving more people than were shown). This bias was further increased when a social hallucination characterized by the false perception of another invisible person (presence hallucination) was induced robotically and repeatedly prior to NEH trials. However, little is known about the brain mechanisms of NEH and rob
