The brain of adults has the ability to make new neurons, a discovery of recent years. However, in what part of the brain are born? So far, neurologists knew that they are born at least in the hippocampus and tuber of Morgagni, but they suspected they also occur in the black substance.

Several investigations have failed in its attempt to corroborate it, but scientists from Stockholm, through experiments in the mouse, have shown that in the black substance there is a constant amount of neurons that, as they die constantly, are also born. According to the results of the scientists, these new neurons belong to those that synthesize dopamine, so now they want to clarify if the process is related to Parkinson's disease.
