What is the fusiform gyrus responsible for?
What is the fusiform gyrus responsible for?
The right fusiform gyrus is responsible for facial recognition, and its activation is reduced in response to happy faces in comparison with HCs. Modulation of activity in the facial processing area has been suggested to contribute to changes in the salience of such emotional stimuli.
What is the occipitotemporal gyrus?
The lateral occipitotemporal gyrus (fusiform gyrus) lies on the basal surface of the temporal and occipital lobes. It forms part of Brodmann area 37, along with the inferior and middle temporal gyri. It is composed of a temporal or anterior portion (T4) and an occipital or posterior portion (O4).
What happens if 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.
Where is the fusiform gyrus located in the brain?
The fusiform gyrus is located on the basal surface of the occipital and temporal lobe. The fusiform gyrus is bounded medially by the collateral sulcus, which separates it from the parahippocampal gyrus.
What part of the brain controls facial recognition?
Face-selective neurons have been found in the amygdala, indicating that this region plays an important role in face recognition (Kosaka et al., 2003). Todorov (2012) proposed that the role of the amygdala in face perception is to motivate the brain to pay attention to novel socially meaningful stimuli (faces).
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).
Where is the Occipitotemporal area?
The fusiform gyrus, also known as the lateral occipitotemporal gyrus, is part of the temporal lobe and occipital lobe in Brodmann area 37. The fusiform gyrus is located between the lingual gyrus and parahippocampal gyrus above, and the inferior temporal gyrus below.
What hemisphere of the brain controls facial recognition?
right cerebral hemisphere
Humans are experts at recognizing faces. Our ability to recognize faces is strongly associated with neural mechanisms in the right cerebral hemisphere. This association is supported by findings from numerous studies of brain-damaged patients and neuroimaging studies of normal and impaired face recognizers.
What part of the brain recognizes names?
There are several regions in the left hemisphere that show greater activation to one’s own name, including middle frontal cortex, middle and superior temporal cortex, and cuneus.
In which hemisphere of the brain is the face recognition area largest?
Structure. The FFA is located in the ventral stream on the ventral surface of the temporal lobe on the lateral side of the fusiform gyrus. It is lateral to the parahippocampal place area. It displays some lateralization, usually being larger in the right hemisphere.
What part of your brain remembers names?
Summary: Psychologists have found a way to improve the recall of proper names. In a recent study, she found that electric stimulation of the right anterior temporal lobe of the brain improved the recall of proper names in young adults by 11 percent.
What does the Occipitotemporal sulcus do?
The LIMA is lateral to the occipitotemporal sulcus, in the inferior temporal cortex, and is important for a variety of lexical tasks including naming and recognition of Braille. This LIMA may be critical for modality-independent lexical processing, rather than an orthographic-specific processes.
What part of the brain remembers faces?
The ability to recognize faces is so important in humans that the brain appears to have an area solely devoted to the task: the fusiform gyrus. Brain imaging studies consistently find that this region of the temporal lobe becomes active when people look at faces.
Which part of the brain is responsible for recognition?
Temporal Lobe. The temporal lobes contain a large number of substructures, whose functions include perception, face recognition, object recognition, memory, language, and emotion.
