Thalamus: Relay station for all sensory info on its way to brain (except olfactory info) Many specialized nuclei (ex: LGN, MGN…don’t have to know these!)

Hypothalamus Communicates with pituitary gland to alter hormone release Involved in feeding, drinking, temperature regulation, sexual behavior, fighting, arousal (activity level)…4 Fs

Basal Ganglia Motor control, but also memory and emotional expression Lose dopamine neurons in SN  Parkinson’s Disease Lose dopamine neurons in caudate & putamen  Huntington’s chorea http://www.uni.edu/walsh/basalganglia-2.jpg Don’t memorize image!!! Just understand that this is a very complex system! thalamus.wustl.edu/ course/cbell6.gif
