PSYCH 101 Lecture Notes - Lecture 6: Basal Ganglia, Motor Coordination, Axon
Document Summary
Pons: a bridge carrying nerve impulses between higher and lower levels of the nervous system. Also plays a role in certain types of learning and memory. Regulates complex, rapidly changing movements that require exquisite timing (ballet dancer) The midbrain: contains clusters of sensory and motor neurons, as well as many sensory and motor fiber tracts that connect higher and lower portions of the nervous system. Nerve impulses from the eyes and ears are organized and sent to forebrain structures involved in visual and auditory perception. Reticular formation: alert higher centers of the brain that messages are coming and then either block those messages or allowing them to go forward ascending and descending. The forebrain: consists of two large cerebral hemispheres. Relay stations for visual, auditory, and body senses (balance and equilibrium) Malfunctioning causes confused thinking and disordered attention that characterize schizophrenic behavior. Surrounding and enveloping the thalamus (5 distinct structures)
