What are the gyri of the temporal lobe?
The temporal lobe is divided into five gyri by four sulci which are oriented largely parallel to the Sylvian fissure. Unfortunately, not all gyri and sulci extend the full length of the lobe and as such not all are present at each angled coronal section. Furthermore, nomenclature is variable.
What structures are located in the temporal lobe?
The temporal lobe subdivides further into the superior temporal lobe, the middle temporal lobe, and the inferior temporal lobe. It houses several critical brain structures including the hippocampus and the amygdala.
What are the main sulci and gyri of temporal lobe?
It is divided into superior, middle, and inferior gyri by the superior and middle temporal sulci. The superior temporal sulcus runs from before backward across the temporal lobe, some little distance below, but parallel with, the posterior ramus of the lateral fissure; and hence it is often termed the parallel sulcus.
What function does the temporal lobe have?
The temporal lobes are also believed to play an important role in processing affect/emotions, language, and certain aspects of visual perception. The dominant temporal lobe, which is the left side in most people, is involved in understanding language and learning and remembering verbal information.
What is the main function of temporal lobe?
What is the main function of the right temporal lobe?
The non-dominant lobe, which is typically the right temporal lobe, is involved in learning and remembering non-verbal information (e.g. visuo-spatial material and music).
What happens if your temporal lobe is 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.
How is the temporal lobe damaged?
Disturbance in function of the temporal lobe may be caused by ischaemic or haemorrhagic damage, as with a cerebrovascular event (CVE). Disturbance of temporal lobe function may also occur with space-occupying lesions and with trauma; it may also be associated with epilepsy.
What are the functions of the left temporal lobe?
Where is the superior temporal gyrus located in the temporal lobe?
The superior temporal gyrus is situated at the topmost aspect of the temporal lobe, lying inferior to the lateral sulcus and superior to the superior temporal sulcus. It extends posteriorly from the temporal pole, ending at the temporoparietal junction, and blending with the angular gyrus and supramarginal gyrus of the inferior parietal lobule.
Is the temporal lobe inferior to the parietal lobe?
• Inferior to the frontal lobe and parietal lobe. The temporal lobe is separated from the frontal lobe by the lateral sulcus (or Sylvian fissure). • Anterior to the occipital lobe.
Where does the blood in the temporal lobe come from?
The temporal lobe receives blood from both the internal carotid artery and the vertebrobasilar artery 4: Venous drainage occurs via two routes 4: The following neurological deficits occur with unilateral or bilateral lesions of the temporal lobes 7: 1.
What are the secondary signs of the temporal lobe?
Secondary signs include unilateral atrophy of the mammillary body or fornix, thinning of the collateral white matter bundle, and loss of grey-white demarcation in the ipsilateral anterior temporal lobe ( Figure 10 ).
