PSYC 2000 Chapter : 2 2 THE BIOLOGY OF THE MIND
Document Summary
Specific forms of brain damage: association areas, more intelligent animals have increased uncommitted or association areas of the cortex, the association areas are not involved in primary motor or sensory functions. How psychologists study the brain: techniques to determine how the brain contributes to behavior, 1. Brain lesions: experimentally destroys brain tissue to study animal behaviors after such destruction, not performed on humans. Electrical stimulation: temporarily disrupts or enhances normal functioning of specific brain areas through electrical stimulation. Similar to lesioning, but doesn"t damage: 3. Ct scan: computed tomography, takes a series of x-rays of the brain, not very detailed, useful for showing stroke damage, tumors, injuries, and abnormal brain structure. Mri: mri (magnetic resonance imaging) uses magnetic fields and radio waves to produce computer- generated images that distinguish among different types of brain tissue, very detailed in comparison to ct scan, 5.
