Abstract
Epinephrine: An endogenous system of memory modulation. Several treatments can affect the processes of learning and memory. Presumably, endogenous mechanisms exist that modulate the storage of information in normal conditions. These mechanisms would be activated by the learning situation and would modulate the strength of memory storage of this experience. In this way, several hormonal systems that are activated as a consequence of a learning situation might act as one of these endogenous memory modulation systems. The present paper discusses several aspects of the relation between epinephrine and memory consolidation that suggest that this hormone might be an endogenous system of memory modulation. Ibis system would modify the strength of the memory trace in normal conditions and it could be also a mechanism through which several treatments modulate memory.
