What is the function of the fusiform gyrus?
The fusiform gyrus is a large region in the inferior temporal cortex that plays important roles in object and face recognition, and recognition of facial expressions is located in the fusiform face area (FFA), which is activated in imaging studies when parts of faces or pictures of facial expressions are presented to …
What are Occipitotemporal regions?
They have proposed the notion of a retinotopically organized occipitotemporal area (Malach et al., 2002), which runs from the posterior fusiform gyrus to the collateral sulcus. Within this region, specific areas respond maximally to different object categories (animals, objects, houses, faces, and words).
What part of the brain controls face recognition?
temporal lobe
The temporal lobe of the brain is partly responsible for our ability to recognize faces. Some neurons in the temporal lobe respond to particular features of faces. Some people who suffer damage to the temporal lobe lose their ability to recognize and identify familiar faces. This disorder is called prosopagnosia.
What causes prosopagnosia?
Prosopagnosia is thought to be the result of abnormalities, damage, or impairment in the right fusiform gyrus, a fold in the brain that appears to coordinate the neural systems that control facial perception and memory. Prosopagnosia can result from stroke, traumatic brain injury, or certain neurodegenerative diseases.
What are the two visual streams named?
Two broad “streams” of projections from primary visual cortex have been identified: a ventral stream projecting to the inferotemporal cortex and a dorsal stream projecting to the posterior parietal cortex.
Can our brain create faces?
It may seem that way, but it is impossible. It is believed that the human brain is incapable of “creating” a new face. Every person you dream of has been someone you have either known personally or merely came across looking through your friend’s Facebook photos.
Why do I have a hard time recognizing faces?
Face blindness, or prosopagnosia, is a brain disorder. It’s characterized by the inability to recognize or differentiate faces. People with face blindness may struggle to notice differences in faces of strangers. Others may even have a hard time recognizing familiar faces.
Why do I not recognize faces?
Prosopagnosia is a brain disorder that makes difficult the recognition of persons by their face. Also called face blindness, prosopagnosia comes from prosopon, the Greek word for face, and agnosia, a medical term for lack of recognition.
