PSYB65H3 Lecture Notes - Peripheral Nervous System, Reticular Formation, Circadian Rhythm
Document Summary
Basic overview of the human brain: how is it built, what is the basic map of the human brain, what does it do, how is it organized. Evolution of the brain: human brain development, how it evolved over time, how individuals formed concept. Divide nervous system into two main partitions: central nervous system. Consists of the: brain, spinal cord, peripheral nervous system. Nerves that run from spinal cord to peripheral body parts. Sends information out and brings information in. When it enters the skull it ceases to exist as a spinal cord". Most simplified version in all vertebrates: fore brain, mid brain, hind brain. Composed of two major things: cerebellum. Movement and integration of sensations to be sent to the motor control system. Taking information from body linking it with motor control: e. g. standing up. Damage: trouble standing up, appear as if drunk, stagger, medulla. Reticular formation: sleep / wakefulness cycles, circadian rhythms, comas.
