New Neuron 'Tells' Stem Cells to Make More Neurons

A new type of neuron has been discovered in the adult brain, which is capable of telling stem cells to make more neurons. . Though the experiments are in their early stages, the finding opens the tantalizing possibility that the brain may be able to repair itself from within. Neuroscientists have suspected for some time that the brain has some capacity to direct the manufacturing of new neurons, but it was difficult to determine where these instructions are coming ...
