What is inferior temporal?
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 function of inferior temporal gyrus in visual system?
The IT processes visual stimuli of objects in our field of vision, and is involved with memory and memory recall to identify that object; it is involved with the processing and perception created by visual stimuli amplified in the V1, V2, V3, and V4 regions of the occipital lobe.
What happens when the inferior temporal cortex is damaged?
After damage to the temporal lobes, typically the right temporal lobe, patients are often unable to identify familiar individuals by their facial characteristics, and in some cases cannot recognize a face at all.
What is distinctive about visual perception in the inferior temporal cortex?
What is distinctive about visual perception in the inferior temporal cortex? Cells respond to an object regardless of the angle of view.
What do the neurons in the inferior temporal cortex do?
Thus, inferior temporal cortex neurons can respond as well to objects when the objects are shown in complex scenes as they do when the objects are shown in plain backgrounds, provided that the object is fixated.
How is the temporal lobe damaged?
As is the case with other traumatic brain injuries, damage to the temporal lobe most often occurs as a result of vehicle crashes, falls, and firearms. Taking steps to prevent these injuries could save you or a loved one a lifetime of the added stress that accompanies traumatic brain injuries.
Which lobe is involved with visual perception?
The occipital lobe
The occipital lobe encompasses the posterior portion of the human cerebral cortex and is primarily responsible for vision.
What sort of receptive fields are found in the inferior temporal cortex?
Inferior temporal cortex neurons have generally been found to have large visual receptive fields that typically include the fovea and extend throughout much of the visual field.
How is temporal lobe damage diagnosed?
The best way to find the cause of a temporal lobe lesion is by having an MRI scan of your brain.
What functions would be lost by a stroke in the temporal lobe?
The temporal lobe is particularly important in language perception, memory, and hearing. A temporal lobe stroke can produce trouble with communication, which is called aphasia.
What are the parts of the inferior temporal cortex?
The human inferior temporal cortex consists of the inferior temporal gyrus, the middle temporal gyrus, and the fusiform gyrus.
Where is the inferior temporal gyrus located in the brain?
The inferior temporal gyrus is placed below the middle temporal gyrus, and is connected behind with the inferior occipital gyrus; it also extends around the infero-lateral border on to the inferior surface of the temporal lobe, where it is limited by the inferior sulcus.
What part of the brain is responsible for visual perception?
From (Carson & Birkett, 2017) we can see that visual representation moves from the retinas into an area of the thalamus called the lateral geniculate nucleus. This information is processed and is then sent to the striate cortex.
Which part of the temporal lobe is unique to humans?
The temporal lobe is unique to primates. In humans, the IT cortex is more complex than their relative primate counterparts. The human inferior temporal cortex consists of the inferior temporal gyrus, the middle temporal gyrus, and the fusiform gyrus.
