What is selective Amygdalohippocampectomy?
This is an alternative to the most common surgery to treat seizures in adults, anterior temporal lobectomy. With selective amygdalohippocampectomy, neurosurgeons remove parts of the amygdala and most of the hippocampus. These two areas are deep in the temporal lobe.
Where is the temporal lobe located?
The temporal lobes sit behind the ears and are the second largest lobe. They are most commonly associated with processing auditory information and with the encoding of memory.
Is temporal lobe lateral or medial?
The temporal lobe is visible on the lateral, medial and basal surfaces of the cerebral hemisphere. On the lateral surface, it is demarcated superiorly by the lateral sulcus (or Sylvian fissure) and extends ventrally to the inferior surface of the cerebrum.
What is Hippocampectomy?
Hippocampectomy is a standard part of temporal lobectomy; because, hippocampus play an important role in epileptogenesis and seizure propagation. However, hippocampus is responsible for creating and retrieving memories and organizing auditory and visual information.
What are three functions of the temporal lobe?
The function of the temporal lobe centers around auditory stimuli, memory, and emotion. The temporal lobe contains the primary auditory complex.
Why is it called the temporal lobe?
The temporal lobe is so named because of its proximity to the temples. It is positioned toward the base of the center of the cortex, just behind the temples. Like all other brain regions, it is not a standalone organ.
Are there 2 temporal lobes?
It is located in the largest division of the brain known as the forebrain (prosencephalon). As with the frontal, occipital, and parietal lobes, there is one temporal lobe located in each brain hemisphere. This vital structure helps process sensory input, including pain and auditory stimuli.
Is hippocampus part of temporal lobe?
The medial temporal lobe (MTL) includes the hippocampus, amygdala and parahippocampal regions, and is crucial for episodic and spatial memory.
What is the insula?
The insula (or insular cortex) is a thin ribbon of gray matter tissue that lies just deep to the lateral brain surface, separating the temporal lobe from the inferior parietal cortex.
What is the main function of amygdala?
The amygdala is commonly thought to form the core of a neural system for processing fearful and threatening stimuli (4), including detection of threat and activation of appropriate fear-related behaviors in response to threatening or dangerous stimuli.
What does a Cingulotomy do?
Cingulotomy is a neurosurgical procedure in which doctors use specialized tools to inactivate brain tissue in areas that are associated with a variety of debilitating diseases, including chronic pain and obsessive-compulsive disorder (OCD).
