Document Summary
Played university students mozart sonata and then participated in iq test. Temporary increase in iq for those who listened to mozart. Twisted to play mozart prenatally to foetus and it will come out a genuis": public refuses to let go, nature and nurture work together here, experience is important, but it isn"t everything. Communication in the mature brain: neuron basic unit of the brain and the rest of the nervous system. Poor myelination occurs usually due to malnutrition. Myelin may account for 50% of brain"s volume: neurogenesis continues with learning and memory, synapses. Created extremely quickly from birth to the end of the brain growth spurt (synaptogenesis) May account for tripling of brain"s weight. Synaptic pruning starts at about 18 months: failure of this is associated with autism (too many is not always better) Important neural connections for our environment are kept: the ones that are used the least are pruned.
