Is fusiform gyrus in amygdala?
Animal studies have identified strong reciprocal projections between the amygdala and fusiform gyrus,9,10 and recent functional magnetic resonance imaging studies have provided evidence of fusiform activity modulation by the amygdala.
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 happens when the fusiform gyrus is damaged?
There are two types of prosopagnosia. Acquired prosopagnosia usually results from injury to the fusiform gyrus, and typically occurs in adults, while congenital prosopagnosia the ability to recognize faces nerve develops.
What brain disorder is the fusiform gyrus associated with?
Some researchers think that the fusiform gyrus may be related to the disorder known as prosopagnosia, or face blindness.
What is prosopagnosia in psychology?
n. a form of visual agnosia in which the ability to perceive and recognize faces is impaired, whereas the ability to recognize other objects may be relatively unaffected.
How long does it take the fusiform gyrus to identify facial features?
A recent human ECoG study showed that category selective activity is first observed in temporal cortex around 100 ms after stimulus onset21. Our results show that human FFA becomes face sensitive in the 50–75 ms window, suggesting that faces are processed more rapidly in temporal cortex than other object categories.
What is FFA psychology?
The fusiform face area (FFA) is a part of the brain located in the fusiform gyrus with a debated purpose. Others believe that the FFA discriminates between any familiar stimuli. Psychologists debate whether the FFA is activated by faces for an evolutionary or expertise reason.
What does the FFA do in the brain?
The fusiform face area (FFA) is a region of the cortex in the inferior temporal lobe of the brain that has been shown to respond most strongly to faces compared with other types of input (e.g., objects) for typically developing individuals.
What is the gyrus rectus?
The gyrus rectus is a portion of the brain located at the medial most margin of the inferior surface of the frontal lobe. While its function is unclear, it may be involved in higher cognitive function (such as personality). Image source.
What happens if the FFA is damaged?
The hypothesis that the FFA is a face-processing module aligned with previous imaging studies that had also linked face perception to this general area of the brain, as well as with cases of patients who had experienced damage to the FFA and subsequently developed a condition known as prosopagnosia, which involves an …
