Thus, injury or damage to one of its structures, the hippocampus, leads to a loss of the ability to store information after the date of injury, keeping the memory of events that occurred before the injury – anterograde amnesia. On the other hand, although still far from fully understanding the biophysical and biochemical bases of memory, it is increasingly clear that what we remember are not the stimuli themselves, but the relations between them, and that the information is stored as changes structural memory. The modulation of many cognitive processes performed by the cerebellum also extended the frontier in the study of different memory processes. Although the printing process and retention of fingerprints is a general function of nerve cells, this does not mean that the activity of memory, complex structure, involving all parts of the brain equally, or that it is a function of the whole crust brain, considered as an indivisible whole. The data that has contemporary physiology and neuropsychology suggest that the activity of the memory is ensured by a complex system of brain sectors that work in coordination, each of which performs its specific contribution to this complex activity. In this sense, current trends indicate that it is essential to perfectly capture the memory or its opposite, forgetting, is but a partial manifestation of memory, and that without it we could not understand what they tell us, what we read or reasoning. Cognitive psychology of memory is now actively engaged in-depth study of these interactions. In regard to scientific research projects currently in development, we can mention two: the first refers to the relationship between experience and changes in gene expression of activated neurons.
