Document Summary
Mozart effect (rauscher et al. , 1993) encouraged parents to let their babies pre and post-natal listen to. So: what accounts for brain growth: myelination insulates the axons and makes sure the signals are still there. Eventually accounts for 50% of the brain volume and vast improve ef ciency of information transfer in the neural cell and produces rapidly till age slow and slows it progressive rate as we age. Myelin can lose signal through the neurons: synaptogenesis. Synaptic development triples the development of the brain at age 2. Between axon of one nerve cell and dendrites of one axon cell to process information on the world around us. Derives of brain stimulation: but synaptic pruning too. We can create so many synapses that account for synaptic pruning: stimulation of the synapses we were generating keeps it alive and with no longer activating it we can kill it off.
