Document Summary
Lesion method: damaging or removing sections of the brain. Electroencephalogram (eeg): detect electrical activity of neurons in particular regions of brain. Pet scan (positron emission tomography): injection of radioactive glucose. Record biochemical changes in brain as they are happening in different locations. Fmri (functional magnetic resonance imaging): uses magnetic fields to measure relative activity of various brain areas during tasks. Cerebellum: concerned primarily with coordination of movement. Directs incoming information from sensory receptors to cerebral cortex. 2 hemispheres of cerebral cortex: left and right. Homunculus: map of motor (or sensory) cortex. Contains broca"s area: speech production (left frontal lobe) Mirror neurons: fire when observing another person doing something. Contains somatosensory cortex: receives information about touch sensations. Can shift functions from damaged to undamaged brain areas. Damage brain can form new synapses, reorganize. Can physically change structure in response to learning.
