What is the function of the left temporal lobe?

The temporal lobe is a relatively important part of the human body. Once the temporal lobe of the human body is abnormal, it will cause many diseases in the body, which will have a great impact on people's daily life and work, and will also affect physical health. Under normal circumstances, when the temporal lobe is mentioned, most people may not be particularly clear about it, and do not know what the temporal lobe does. The following will introduce the functions of the left temporal lobe to you.

Function of the left temporal lobe

Areas 41 and 42 of the superior temporal gyrus and the transverse temporal gyrus are the auditory cortex areas. The posterior part of the superior temporal gyrus in the dominant hemisphere is the auditory speech center, called the Wernicke area, which also includes the posterior part of the middle temporal gyrus and the supramarginal gyrus and angular gyrus of the superior parietal lobule. The hook of the hippocampus is the olfactory and taste center. The front part of the temporal lobe is the mental cortex. Human emotions and mental activities are not only related to the orbitofrontal cortex, but also have a lot to do with the temporal lobe. The hippocampus is related to memory.

The neocortex of the temporal lobe is connected to the neocortex of the frontal, parietal and occipital lobes by fibers; the hippocampus is connected to the basal ganglia and limbic system; there are also connections between the two temporal lobes. The auditory cortex receives impulses from the medial geniculate body and from the contralateral temporal lobe via the corpus callosum. The uncinate fasciculus bypasses the Sylvian fissure to connect the temporal and frontal poles. The cingulate bundle has fibers to the hippocampus. The anterior part of the cingulate bundle is connected to the uncinate fasciculus. It also receives impulses from the anterior and dorsal nuclei of the thalamus and the reticular nucleus of the brainstem. The efferent fibers of the temporal lobe include the corticogeniculate fasciculus and the corticomesencephalic fasciculus.

Which department does left temporal lobe infarction belong to?

It generally belongs to neurology, and the treatment of left-sided cerebral infarction mainly includes the following aspects. First, you need to improve cerebral blood circulation. If you are in the super new period, you can choose thrombolytic therapy. After the super new period, you can choose comprehensive treatments such as antiplatelet aggregation, anti-inflammation, anticoagulation, fibrinolytic therapy, and volume expansion.

Neuroprotective agents such as nimodipine or citicoline are needed to protect brain cells and improve tolerance to ischemia and hypoxia. There are also other drugs such as levofloxacin that can reduce damage to brain nerves and promote the recovery of neurological function. Rehabilitation treatment is also critical.

Left temporal lobe suture infarction

Lacunar infarction is a type of cerebral infarction, which is relatively mild in severity and generally does not have any obvious sequelae.

Cerebral infarction is a type of neurological disease, which is mainly caused by the blockage of intracranial blood vessels, resulting in ischemia and hypoxia of the brain tissue nourished by the blood vessels, which in turn leads to tissue edema and increased intracranial pressure, thus affecting the function of the brain.

Clinically, it can manifest as movement or sensory disorders of the limbs, temporal lobe dysfunction or cognitive dysfunction, etc. In severe cases, it can lead to coma or even death of the patient.

This type of disease generally has a poor prognosis, mainly because brain cells are a type of non-renewable cells. Cerebral infarction will lead to impaired brain cell function or even cell death, and these dead brain cells are non-renewable. In this case, the brain can only partially function by relying on these remaining brain cells. Therefore, the overall prognosis is very poor.
