PSYB65H3 Lecture Notes - Lecture 1: Peripheral Nervous System, Spinal Cord, Reticular Formation
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. 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. 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. Thalamus: relay center, information coming from spinal cord to other areas of the brain.
