Memory and trauma impact: a development approach

Acta Médica Portuguesa
Maria Moura, José Estrada

Abstract

The purpose of this article is to review the main neuroanatomic structures and the neurotransmission process involved at memory. Memory is dynamic based on the reunion of aspects of neuronal activation, in a process based on the individual experiences. It will be described the importance of limbic regions and their interaction during processing, codification and consolidation of a memory - each one related with neuronal rebuild. Further the authors describe the memory types known (explicit and implicit memories); the characteristics and their progress during normal development. It will be addressed other issues like child amnesia, retrieval and trauma. Forgetting is one of the essential features at explicit memory. Many studies describe a U inverted effect at memories with emotional value. Events with moderate or elevated emotional intensity are printed as important (by limbic structures like amygdala and orbito-frontal cortex) being more easily recorded. If the experience is very intense the explicit memory codification processing at hippocampus will be inhibited and as a consequence also does the retrieval. Meanwhile the implicit memory will remain and may constitute pathologic memories. The psychological trauma blocks the ex...Continue Reading

Amygdala and Midbrain Dopamine

The midbrain dopamine system is widely studied for its involvement in emotional and motivational behavior. Some of these neurons receive information from the amygdala and project throughout the cortex. When the circuit and transmission of dopamine is disrupted symptoms may present. Here is the latest research on the amygdala and midbrain dopamine.
