PS101 Lecture Notes - Lecture 4: Auditory Cortex, Visual Cortex, Cerebral Cortex
Document Summary
Ps101 chapter 4: sensaion and percepion (cid:1) (cid:1) (cid:1) Hindbrain cerebellum, medulla, pons: medulla. Controls vital bodily functions such as heartbeat, breathing, blood pressure, circulation, coughing, and swallowing: cerebellum. Helps provide smooth, coordinated body movement: pons. Assists in control of movement: lower on the nervous system hierarchy, i. e. transected cat no balance. Midbrain reticular formation: contains several neural centers that control some motor reactions and some sensory functions, integration of sensory processes. Limited auditory and visual functions: reticular formation. Regulates attention and alertness (sleep and arousal) Forebrain cerebral hemispheres: largest and most complex region, relay (transmitting information) and regulation. Relay system for all sensory information (except smell) Regulation of basic biological needs (fighting, fleeing, feeding, mating: limbic system. Covers the cerebral hemispheres; primarily responsible for higher mental processes (language, memory, thinking) Frontal lobe: motor cortex directing voluntary movement, planning, logical reasoning, problem solving, and judgment. Parietal lobe: somatosensory cortex, sense of touch, position in space.
