Länk - Hippocampus, stress, råttor och depression
The stress consisted of young rats being exposed to older and meaner rats, who ganged up on and sometimes bit the younger rats. (This is why they use rats instead of people.) The hippocampus, active in processing emotions and memories, is one of two areas of rat and human brains where neurogenesis occurs. The stress of an encounter with an aggressive older rat didn’t seem to slow the generation of new neurons, but it did significantly lower the survival rate of the new brain cells. The loss of these brain cells may be one factor in the development of depression.
