What is a limbic system

Limbic system

English: limbic system

1 definition

The limbic system is a phylogenetically very old part of the brain that is composed of several structures. Achievements such as the control of the functions of drive, learning, memory, emotions as well as vegetative regulation of food intake, digestion and reproduction are ascribed to him.

Note: The limbic system is not the only place in the brain where these services are generated.

2 structures of the limbic system

The limbic system includes various structures, some of which are anatomically far apart and are characterized above all by the fact that they have a similar or common function:

3 Function of the Limbic System

3.1 Corpus mamillare

The corpus mamillare is mainly involved in memory formation within the framework of the Papez neuron circle. It can also affect sexual functions.

3.2 Cingulate gyrus

The cingulate gyrus can influence vegetative functions and is also responsible for the psycho- and locomotor drive.

3.3 Parahippocampal gyrus

The main purpose of this gyrus is to relay information from other parts of the limbic system to the hippocampus. He is also involved in memory formation.

3.4 Hippocampus

The hippocampus is of great importance for memory formation, but can also influence vegetative and emotional functions.

3.5 Corpus amygdaloideum

The amygdala is primarily used to store memory content that has moved people very emotionally. It can also influence vegetative and sexual functions.
