Document Summary

Coordinates info coming into and out of the spinal cord. Damage to the hindbrain is much more severe than damage to the midbrain or forebrain. Contains reticular formation (regulates sleep, wakefulness, and arousal) Relays info from cerebellum to rest of the brain. Receives information from the eyes, ears and skin and moves us towards the stimulus. Controls complex cognitive, emotional, sensory, and motor function. Relay and filters information from the sense and sends the information to the cerebral cortex. Actively filters information, giving more weight to some inputs and less weight to others based on importance. Thalamic syndrome = severe pain, extreme sensitivity to touch. Regulates body temperature, thirst, hunger, and sexual behavior. Lesions to hypothalamus = overeating or lack of interest in food (starvation) Thoughts about sex cause messages to be sent from the cerebral cortex to the hypothalamus to trigger the release of hormones. Electrical stimulation to different areas of hypothalamus can cause aggressive behavior or intense pleasure.
