What is the structure of the limbic system?

located in the interior of the brain lies a set of structures jointly referred to as a limbic system. The main role in emotions and motivation include the main organs of Hypothalamus, Amygdala and Hippocampus. The parts are arranged in a loop, connected net, which is located around the upper part of the brain stem. It communicates with the prefrontal bark and is also called the "emotional brain". The ripening of the nerve tube is determined by the central nervous system consisting of the brain and spinal cord. Telencephalon becomes a brain where the structures of the limbic system are located. While Amygdala determines the relevance of fear, this limbic system structure generates physiological reactions such as racing heart, sweating and increased respiratory frequency. It is a protective response to a perceived threat allowing behavior to save life. It is stored memories of reactions to scary events, which can cause a mental disorder. This small pair of almond organs located at the bottom of the Caudate loop is responsible for the response of the "fight or flight".

In the learning process, hippocampus is capable of consolidation - attaching a physical image to memory to search for its search. Until this happens, the storage of information is brief. The hippocampal structure of the limbic system is primarily involved in the actual learning of skills or task; It is not a place of permanent storage. Othza are responsible brain areas such as bark.

Psychiatric conditions were associated with damage to the structure of the limbic system. For example, in schizophrenic patients there are several areas including hippocamp and amygdala significantly smaller than usual. Schizophrenia is a mental disorder causing problems with the idea, perception and cognitive abilities.

The increase in the chamber suggests a lack of brain tissue, which is also associated with dementia, for example in Alzheimer's disease. In Alzheimer's disease, the degeneration of brain tissue begins in hippocamp, which affects memory and knowledge.Scientists think that people with schizophrenia can be born with anomalies or that they have appeared sometime during early childhood. Those with Alzheimer's disease have gradually developed abnormal brain changes over time, usually much later in life.
