What is incomplete hippocampal inversion?
Abstract. Incomplete hippocampal inversion (IHI) is an anatomical variant of the human brain resulting from an arrest in brain development, especially prevalent in the left hemisphere. We hypothesized that IHI is more common in schizophrenia and contributes to the well-known hippocampal structural differences.
What is hippocampus Malrotation?
Hippocampal malrotation (HIMAL) describes an atypical appearance of the hippocampus with abnormal medial location along the choroid fissure, round or pyramidal shape and/or verticalization of the collateral sulcus.
What is left hippocampal Malrotation?
HIMAL is a developmental malformation that predominantly affects the left hippocampus in males, and is more frequently found in children with prolonged FSE than in controls. These data provide further evidence that HIMAL represents a pathological error in brain development rather than a normal variant.
What is hippocampal sclerosis?
Hippocampal sclerosis is the commonest cause of drug-resistant epilepsy in adults, and is associated with alterations to structures and networks beyond the hippocampus.In addition to being a cause of epilepsy, the hippocampus is vulnerable to damage from seizure activity.
What is hippocampal sulcus?
The hippocampal sulcus, also known as the hippocampal fissure, is a sulcus that separates the dentate gyrus from the subiculum and the CA1 field in the hippocampus.
How many hippocampus do humans have?
Because the brain is lateralized and symmetrical, you actually have two hippocampi. They are located just above each ear and about an inch-and-a-half inside your head.
What does the left hippocampus control?
The hippocampus on the language-dominant side (usually the left side of the brain in most people) has a much more important role in memory than the non-dominant side. This hippocampus functions in verbal or language memory and short-term memory.
Can hippocampal sclerosis be cured?
Conclusions: Our findings demonstrated that anteromedial temporal lobectomy is a safe and effective treatment method in well-chosen patients with hippocampal sclerosis. This surgical procedure can be performed with a low rate of morbidity even in relatively new epilepsy surgery center.
What is hippocampal damage?
Hippocampus damage can particularly affect spatial memory, or the ability to remember directions, locations, and orientations. Because the hippocampus plays such an important role in the formation of new memories, damage to this part of the brain can have a serious long-term impact on certain types of memory.
