What is the hippocampal formation?

Hippocampial formation is part of the limbic system and plays a key role in memory and learning. The hippocampial formation consists of hippocamp and gyrus dentate and is located on a medium temporal lobe in the brain. Hippocampus in the shape of a marine horse has two halves, each of which is on one side of the brain. The fibrous material threatens fornix and mamillary bodies are considered to be part of the hypothalamus. These parts of the brain are also part of the limbic system. This includes the whole process, from the search for edible food to the operation of the body to spend it. If it is considered in terms of evolution, the hippocampal formation of the Jestarší part of the brain itself. It may seem that the brain has partially developed memory and learning through a successful placement of edible food sources.

Fear and emotional reactions are also responsible for the limbic system. Controls the physiological effects of everyone such as pulse, blood pressure and the expressions of the popularityCHECKED. The fight or flight response to fear is also checked in this part of the brain, as well as spatial navigation and consciousness. Learning, memory, emotions and key functions are all connected as part of the same brain processes.

Hippocampial production is often one of the first areas affected by Alzheimer's disease and can also be damaged by seizures, herpes encephalitis and severe oxygen loss into the brain. Oxygen loss may occur due to almost drowning, heart attacks, sleep problems and carbon monoxide poisoning. The lesions found in Mamillary Bodies and Fornix also affect the formation of hippocampal and can lead to memory changes.

Hippocampal damage affects both short and long -term memory. Short -term memory is still possible, but it shortens before it was before, and lasts only a few minutes. Long -term memory can be permanently damaged. The memories obtained before damage are not affected, but any new memories obtained cannot be stored or triggered. Most of the challenges obtainedThe cum and information on the function of hippocamp formation will learn from the study of patients who have suffered damage to the area.
