What happens if the inferior temporal gyrus is damaged?

What happens if the inferior temporal gyrus is damaged?

With respect to semantic dementia, the study concluded that “the middle and inferior temporal gyri [cortices] may play a key role” in semantic memory, and as a result, unfortunately, when these anterior temporal lobe structures are injured, the subject is left with semantic dementia.

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 …

How might damage to the inferior temporal cortex affect behavior?

Damage to the temporal lobes can result in: Difficulty learning and retaining new information. Impaired factual and long-term memory. Persistent talking. Difficulty in recognising faces (Prosopagnosia)

What is the likely perceptual consequence of damage to medial temporal gyrus?

Medial temporal lobe damage impairs representation of simple stimuli. Medial temporal lobe (MTL) damage in humans is typically thought to produce a circumscribed impairment in the acquisition of new enduring memories, but recent reports have documented deficits even in short-term maintenance.

What can happen if the temporal lobes are damaged?

Right temporal damage can cause a loss of inhibition of talking. The temporal lobes are highly associated with memory skills. Left temporal lesions result in impaired memory for verbal material. Right side lesions result in recall of non-verbal material, such as music and drawings.

Can damage to the temporal lobe cause hearing loss?

Central Hearing Loss Finally, hearing loss can occur after direct damage to the parts of the brain that process sound, such as the temporal lobe. This type is known as central hearing loss.

What happens when the fusiform gyrus is damaged?

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 do you mean by fusiform?

Fusiform means having a spindle-like shape that is wide in the middle and tapers at both ends. It is similar to the lemon-shape, but often implies a focal broadening of a structure that continues from one or both ends, such as an aneurysm on a blood vessel.

What happens if you injure your temporal lobe?

What does damage to the medial temporal lobe do?

Damage to the hippocampal region and related medial temporal lobe structures (perirhinal, entorhinal, and parahippocampal cortices) impairs new learning (anterograde amnesia) as well as memory for information that was acquired before the damage occurred (retrograde amnesia).

What happens if the right frontal lobe is damaged?

Some potential symptoms of frontal lobe damage can include: loss of movement, either partial (paresis) or complete (paralysis), on the opposite side of the body. difficulty performing tasks that require a sequence of movements. trouble with speech or language (aphasia)

What is the function of the inferior temporal gyrus?

The inferior temporal gyrus is the anterior region of the temporal lobe located underneath the central temporal sulcus. The primary function of the occipital temporal gyrus – otherwise referenced as IT cortex – is associated with visual stimuli processing, namely visual object recognition,…

What are the efferent areas of the fusiform gyrus?

One would expect that the neuronal differences in the FG would have a similar effect on efferent areas, namely the amygdala, inferior frontal gyrus, and orbitofrontal cortex.

Where is the gyrus located in the brain?

It refers to a convolution or elevation on the temporal lobe of the cerebral hemispheres that lie beneath the middle temporal sulcus and stretches to the inferior sulcus. It is abbreviated as ITG and is also known as “Gyrus Temporalis Inferior”.

Which is more complex the IT cortex or the inferior temporal cortex?

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.
