PSYC 242 Study Guide - Midterm Guide: Inferior Colliculus, Superior Colliculus, Basal Ganglia
Document Summary
The mesencephalon is the only division within the midbrain. Tectum - roof of mesencephalon, includes superior & inferior colliculus. Inferior colliculus focus sound superior colliculus focus vision. Tegmentum - floor of mesencephalon, contains next 3 things. Periaqueductal grey matter - stimulation cause release of endogenous opiates. Red nucleus relay of movement info from cortex to cerebellum/spinal cord. Substantia nigra - major dopamine producer damage parkinson"s. Diencephalon - the thalamus, hypothalamus, and pituitary gland. Thalamus - anteroom, room before rooms, gateway for the cortex. Corpus callosum - found in 2 areas and connects the 2 hemispheres of the brain. Telencephalon - contains limbic system, basal ganglia, and cerebral cortex. Hippocampus - very important in memory consolidation, the gateway to memory. Mammillary bodies - damage cause confabulation, alcoholics no thiamine. Amygdala - involved in the emotional of stimuli, the fear response. Retrograde amnesia forget past anterograde amnesia no future mem. Confabulation - making up memories that never happened.
