What is a limbic system?

Limbic system, named after the Latin word limbus for Edge, is the innermost part of the brain, wrapped around core chambers. It is full of cerebrospinal fluid and various white matter clusters that do not play in a cognitive role.

This system is called the "old mammal system" or "mammalian brain" in the popular model of the Triune brain, which divides the brain into three parts depending on their position and functions. Other parts are a reptile brain or brain stem and cerebral cortex or neocortex. They are responsible for "lower" and "higher" behavior. and thalamus. Everyone plays an important role in the production of things smoothly in the brain. Analog structures can be found in almost all mammals such as dogs, cats and mice, although not reptiles that have only a brain strain.

The limbic system is home to emotions, motivation, regulation of memories, interfaces between emotional states and memories of physical stimuli, physiological autonOmnost regulators, hormones, "fighting or flight", sexual excitement, circadian engravings and some decision -making systems. This is what is "cheated" when people are dependent on hard drugs. Given that the dependence occurs in the "lower" part, the "prevail" of the brain, we cannot rationally consider its effects, and therefore it may be difficult to recover and avoid relapse. Rats provided by switches connected to electrodes that electrically stimulate their Accumbens core will continue to press the switch to exclude all others, including food or gender.

At the peak of the limbic system there is a cortex, the "brain of thinking". Thalamus acts as a connection between them. The bark has evolved depending on the limbic system that was present in front of it. Every beneficial adaptation in Neocortex had to "play nicely" and effectively cooperate to justify its own maintaining the overall fitness of the organism. Pineal Gland, the famous part of the limbic system located in the epithalamus is rare forFor example, the brain organ of the rest, which was much larger and differentiated in the former part of our evolutionary history.
