PSY 150 Lecture Notes - Lecture 3: Cerebral Cortex, Pituitary Gland, Basal Ganglia
Document Summary
Bottom-up organization basic functions are in the lower parts of the brain; more complicated skills are higher up. Coordinates information coming into/out of the spinal cord; controls the most basic functions to sustain life (respiration, alertness, & motor skills) Contains: medulla coordinates heart rate, circulation, and respiration. Reticular formation regulates sleep, wakefulness, and levels of arousal. Cerebellum orchestrates proper sequence of movements to allow for activities that involve complex coordination (fine motor skills) The pons - relays information from the cerebellum to the rest of the brain. Sits on top of hindbrain, controls life maintaining functions: made of: Tectum orients an organism in the environment; receives stimuli input and orients organism towards the stimuli. Tegmentum involved in movement and arousal; orients organism towards stimuli. Highest level of the brain; controls complex emotional, sensory, and motor functions. Thalamus relays and filters information from the senses.
