Neuron Transplants Can Repair Brain Circuits

A new study by Harvard University neuroscientist Jeffrey Macklis and colleagues suggests it is possible to transplant fetal neurons into a part of the mouse brain that does not normally generate new brain cells, and they will repair abnormal circuits. In this case, the researchers repaired a genetic defect that causes obesity, but that was not the goal of their work which was to establish proof of principle that transplanted neurons can integrate into existing faulty brain circuits and restore them...
