Document Summary

Psych 1000 - lecture 6 - biological bases of behaviour (part 2) The thalamus: relay centre for sensory and motor information to different part of the cerebral cortex, except small, also sends information from the cortex to the medulla and cerebellum. The cerebellum: the little brain , located at the back of the brain stem, fundamental to the coronation of voluntary movement and balance, other functions. The limbic system: located on both side of the thalamus, collection of structures, hippocampus, amygdala, hypothalamus, functions, processes information about our internal states, ex. heart rate, blood pressure, plays a key role in emotional experiences and memory formation. Amygdala: consists of two lima bean sized neural clusters, associated with the experience of different emotions, particularly negative ones, ex. fear, key role for fear conditioning. Hippocampus: associated functions, processing conscious episodic memories, key to creating mental maps, working with the amygdala to from emotionally charged memories.
