Document Summary
Corpus callosum is a neural bridge that acts as communication link between two hemispheres. If corpus collosum is cut, visual input to one hemisphere is restricted by projecting stimulus to only one side of visual field. Neural plasticity the ability of neurons to change in structure and function. Early experiences during brain development can alter brain areas involved in certain skills. Greater amount of synapses in children allow for greater chance of recovery from damage to brain: adults can also maintain or recover functions by surviving neurons that modify themselves (extended axons, increased neurotransmitters, etc. ) Heritability coefficient extent to which the degree of variation in a particular characteristic among a group of people can be attributed to genetic factors. Concordance the likelihood that two people share a particular characteristic. Adoption study study of children who were adopted by comparing to both sets of parents: more similar to biological: genetic influence, more similar to adoptive: environmental influence.
