Sympathetic (activated at state of arousal) and parasympathetic nerves (activated at a state of relaxation) Not fully developed until late teens/early twenties. Control fine motor movement important for working memory (episodic memory) , but not reference memory (procedural memory) Broca area located: part of a production of language. Contralateral organization: information left and right side crosses over. Language processing (wernicke"s area): comprehension of language. Two hemispheres separated by the longitudinal fissure.
