Normal form from biological motion despite impaired ventral stream function
We explored the extent to which biological motion perception depends on ventral stream integration by studying LG, an unusual case of developmental visual agnosia. LG has significant ventral stream processing deficits but no discernable structural cortical abnormality. LG's intermediate visual areas and object-sensitive regions exhibit abnormal activation during visual object perception, in con...
متن کاملBlindness to form from motion despite intact static form perception and motion detection.
We studied the motion perception, including form and meaning generated by motion, in a hemianopic patient who also had visual perceptual impairments in her seeing hemifield as a result of a lesion in ventral extrastriate cortex. She was unable to recognise 2- or 3-dimensional forms, and even borders, generated by motion alone, failed to recognise mimed actions or the Johannson 'biological motio...
متن کاملRole of dorsal and ventral stream development in biological motion perception.
Little is known about the functional development of dorsal and ventral visual streams. The right posterior superior temporal sulcus (pSTS) represents a pivotal point of the two streams and is involved in the perception of biological motion. Here, we compared brain activity between children (aged 5-7 years) and adults (aged 20-32 years) while they were viewing point-light dot animations of biolo...
متن کاملVentral aspect of the visual form pathway is not critical for the perception of biological motion.
Identifying the movements of those around us is fundamental for many daily activities, such as recognizing actions, detecting predators, and interacting with others socially. A key question concerns the neurobiological substrates underlying biological motion perception. Although the ventral "form" visual cortex is standardly activated by biologically moving stimuli, whether these activations ar...
متن کاملImpaired Recognition of Communicative Interactions from Biological Motion in Schizophrenia
BACKGROUND Patients with schizophrenia are deficient in multiple aspects of social cognition, including biological motion perception. In the present study we investigated the ability to read social information from point-light stimuli in schizophrenia. METHODOLOGY/PRINCIPAL FINDINGS Participants with paranoid schizophrenia and healthy controls were presented with a biological motion task depi...
