The limbic system?

*The limbic system consists of the totality of the cerebral structures situated in the median and profound area of the brain, with a major role as far as the memory and emotions are concerned, as well as behavior elaboration. The limbic system is the essential element that makes the connection between the cortex and the older cerebral formations. This, also known as the limbic brain, is responsible for affectivity and memory. Its nervous formations aren’t included in the cortex. Its essential function is to maintain the adaptation to the social environment. The empathy, interpersonal relations, convictions, beliefs, the impulse to attack or defend, the feeling of security or insecurity are coordinated by the limbic system, not by the cortex. That is why the emotions cannot be controlled by reason; reason can only at most control emotions. The limbic system has a certain autonomy from the brain. An apparently intense emotion provokes a reaction of the limbic system and blocks any reactivity of the cortical areas. The limbic system has a selective role, being some sort of filter that insures a selection using the criterion of pleasure, motivation, interest, success. The information considered interesting first pass by it. The limbic system stimulates the areas of the cortex to which the positive information refers to (in case of negative information, affectively, the information no longer reaches the brain, being stopped by the limbic system). It was proved that people react before speaking or thinking. Also, non-verbal information comes much sooner than verbal information, the non-verbal communication answering (most often before verbal communication) to stimuli. Thus, the communication between the limbic system - cortex is unilateral. The limbic system also has an important role in generating long term memory. Thus, the person registers the pleasant or unpleasant character of the stimuli, in the future avoiding the unpleasant stimuli, but not the pleasant ones. Thus, the limbic system, by storing all the memories, is responsible for gaining experience. Also, the limbic system has a cognitive role which consists of generating images and using them. Thus, the limbic system is the headquarters of affectivity, long term memory and imagination. The limbic system is impenetrable to any rational logic.

Un comentariu:

  1. Be careful. Assumptions like 'the limbic system is responsible for memory and imagination' are quite obtuse
