Thus, the formulation of synapses is accompanied by the death of 20 to 80 percent of neurons, although this is dependent on the region of the brain. It is however fortunate that the prenatal period is accompanied by the production of more neurons by the neural tube capable of always satisfying the needs of the brain.
