Adult brain connections are difficult to change, unlike what happens with the brain of the smallest, whose experiences are shaping and changing their brain connections while it is developing. But is it possible to rejuvenate adult brain and make it as flexible as when young? That's what we just got a team of researchers from the University of California, Irvine, as stated in the journal Neuron.

To achieve this, scientists have transplanted embryonic certain type of neurons that express the neurotransmitter GABA discovering that the mice used in the experiment had a vision problem that develops early in life, called amblyopia, managed after transplant, new period of plasticity in the brain allowing the adult brain rewiring and perfectly seen that mice, eliminating the problem of vision.

Thus, adult brains again be young again reactivating brain plasticity, rapid and robust changes in the neural pathways and synapses: "Several weeks after transplantation, when the visual system of the donor animal crossed their critical period, amblyopic mice began to see with normal visual acuity, "says Melissa Davis, who led the study.

What applications can have this discovery? The study paves the way for new treatments related to the normal development of the brain such as schizophrenia and autism, currently incurable brain disorders.
