PSY 2012 Lecture Notes - Lecture 7: Corpus Callosum, Spinal Cord, Reticular Formation
Document Summary
Brain lesioning: abnormal disruption in the tissue of the brain resulting from injury or disease. Electrical recording: detects brain wave activity. Ct (or cat) scan images -> three dimensional. Mri -> brain structure fmri -> brain function. Hindbrain: adjacent to top part of spinal cord. The brain major structures and their function. Corpus callosum: bridge of fibers passing information between the two cerebral hemispheres. Thalamus: relay center for incoming sensory information. Involved in sensing, thinking, learning, emotion, consciousness, and voluntary movement. Amygdala: limbic system structure involved in emotion and aggression. Hippocampus: limbic system structure involved in learning and memory. Spinal cord: transmits information between brain and rest of body; handles simple reflexes. Reticular formation: group of fibers that carries stimulation related to sleep and arousal through brain stem. Medulla: regulates vital functions such as breathing and circulation. Cerebellum: coordinates fine muscle movement, balance. Pituitary gland: master gland that regulates other endocrine glands.
