Document Summary
Birth: brain at 30% of its adult weight: must be borne with an immature brain for child birth. Age 2: 70% (more than doubled: dynamic changes in brain. Age 6: at 90% of its adult weight: building of synapses adds heft. They"ll then be myelinated which also adds weight: creating synapses but also pruning out what we don"t need, brain continues to improve and change long into 30s (90% is misleading) Environmental influences have a stronger chance to influence the cerebral cortex. Brain is not yet lateralized, so infants and young children"s brains have more plasticity than adolescents and adults. If part of the brain is lost or damaged, they can just be shifter over to another part of the brain (fast in children, very slow in adults) Controversy: how to view the first 3 years of life. 40% of 3-month-old infants are regular viewers of dvds.
