Memory is one of the main functions of the brain. Without it, we could not learn anything and would not gain any benefit from the experience. Memory is not localized to any specific area of the cerebral cortex. What we learn is dispersed across countless interconnected neurons. Memory is believed to be based in the nucleus of neurons, which do not undergo any changes when information is stored in short-term memory (a telephone number, a lesson we are studying, etc.), but undergo chemical changes when information is stored in long-term memory (experiences). , memories, etc.). There is a connection between memory and emotions, since we usually remember better what is pleasant to us or, conversely, what is very unpleasant. The forgetting mechanism works in the same way: it works as a defense system, erasing what causes us fear or anxiety.
