What does the Inferotemporal cortex do?
The inferior temporal (IT) cortex plays a critically important role for the visual recognition of objects. The visual recognition system in the IT cortex is distributed in multiple areas, including area TE and the rhinal cortex.
What is striate cortex?
The striate cortex is the part of the visual cortex that is involved in processing visual information. The striate cortex is the first cortical visual area that receives input from the lateral geniculate nucleus in the thalamus.
What is the visual cortex?
The visual cortex is the primary cortical region of the brain that receives, integrates, and processes visual information relayed from the retinas. It is in the occipital lobe of the primary cerebral cortex, which is in the most posterior region of the brain.
What is the ventral pathway?
The ventral visual pathway is a functional stream involved in the visual recognition of objects. An analogous pathway is present in the human brain. This pathway consists of visual input from primary visual cortex V1 relayed through areas V2 and V4, and ultimately projected into the inferior temporal cortex.
What happens if the Inferotemporal cortex is damaged?
Effects of IT lesions Sometimes the deficit is a general impairment in visual recognition or visual agnosia; more rarely it can be a specific difficulty in recognizing faces (prosopagnosia), colors (achromatopsia) or even a category specific agnosia such as difficulty in recognizing animals or man-made objects.
What is meant by Inferotemporal?
Medical Definition of inferotemporal 1 : being the inferior part of the temporal lobe of the cerebral cortex also : situated or occurring in, on, or under this part the inferotemporal gyrus inferotemporal cortical neurons inferotemporal lesions.
What is Inferotemporal cortex?
Inferior Temporal (IT) Cortex is the cerebral cortex on the inferior convexity of the temporal lobe in primates including humans. It is crucial for visual object recognition and is considered to be the final stage in the ventral cortical visual system.
What is the Cuneus?
The cuneus (plural: cunei) is a wedge-shaped region on the medial surface of the occipital lobe.
Where is your visual cortex?
occipital lobe
The primary visual cortex is found in the occipital lobe in both cerebral hemispheres. It surrounds and extends into a deep sulcus called the calcarine sulcus.
How does the visual cortex work?
The primary visual cortex, often called V1, is a structure that is essential to the conscious processing of visual stimuli. When visual information leaves the retina, it is sent via the optic nerve (which soon becomes the optic tract) to a nucleus of the thalamus called the lateral geniculate nucleus.
Where is the ventral pathway?
The ventral pathway was described as coursing through the occipitotemporal cortex to the anterior part of the inferior temporal gyrus (area TE)[1, 2], with a likely extension into the ventrolateral prefrontal cortex (VLPFC/area FDv)[3].
What does the lingual gyrus do?
The lingual gyrus is a structure in the visual cortex that plays an important role in the identification and recognition of words. Studies have implicated the lingual gyrus as being involved in modulating visual stimuli (especially letters) but not whether or not the stimulus was a word.
