Document Summary
Lecture 18: chemical control of brain and behavior: overview: the secretory hypothalamus, by secreting chemical directly into the blood stream, the secretory hypothalamus can influence functions throughout both the brain and the body. System (ans) controls the responses of many internal organs, blood vessels and glands. Finally, the cns consists of several related cell groups that differ with respect to the neurotransmitter they use. Components of the ns that operate over long distance and time: Diffuse modulatory system (axonal projections that determine arousal and mood) Location: adjacent to dorsal thalamus; pituitary hangs off. Function: integrates somatic and visceral responses in accordance with the need of the brain. Structure: each side of the hypothalamus has three functional zones: lateral, medial, and periventricular. The lateral and medial zones have extensive connections with the brain stem and the telencephalon and regulate certain types of behavior. The periventricular zone is in charge to synchronize circadian rhythms with daily light-dark cycle.
