PSYCH 101 Lecture Notes - Lecture 8: Twin, Neuroplasticity, Genetic Variation
Document Summary
Corpus callosum is a neural bridge that acts as communication link between two hemispheres. Lateralization relatively greater localization of a function in one hemisphere or the other mathematical, and logical abilities. For most people, left hemisphere involved in verbal abilities, speech, Right hemisphere involved in mental imagery, musical/artistic abilities, and. Left: positive emotions, right: negative emotions ability to perceive and understand spatial relationships. 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. )
