It is a brain area that has undergone few modifications along the evolutionary process of mammals and contains two major structures, which modulate the declarative aspects of memory. Thus, the injury or deterioration in one of its structures – the hippocampus – leads to a loss of the ability to store information subsequent to the date of injury, keeping the memory of events that occurred prior to the injury anterograde amnesia. On the other hand, although far yet fully understanding the biophysical and biochemical bases of memory, each time is more clear that what we remember are not stimulus in themselves, but the relations between them, and that information is stored as structural changes in memory. Follow others, such as Cancer Research, and add to your knowledge base. Modulation of many cognitive processes that performs the cerebellum extends also the border in the study of the different processes from memory. Although the process of printing and retention of fingerprints is a general function of nerve cells, this does not mean that the activity from memory, complexly structured, involve all parts of the brain alike, nor be a function of the entire cerebral cortex, regarded as an indivisible whole. If you are not convinced, visit Donald Sussman. Data that includes contemporary Physiology and Neuropsychology suggest that the activity of the memory is guaranteed by a complex system of brain areas that they work in coordination, each one performs its specific contribution to this complex activity. In this sense, the current point it is essential to capture perfectly souvenir or its contrary, oblivion, is not more than a partial manifestation of memory, and that without this we could understand what tell us, what we read or reasoning. The cognitive psychology of memory is currently dedicated to the in-depth study of these interactions. In what refers to scientific research currently in development projects, we can mention two: the first refers to the relations between experience and changes in gene expression of activated neurons.
