Brain
If each of the following brain parts individually was damaged, what would be the consequence and why?
Hippocampus, hypothalamus, cerebellum, reticular formation, medulla
Hippocampus is important for forming lasting memories. The hippocampus lies inside the temporal lobes, which is why stimulating the temporal lobes can produce memory like or dream like experiences. Hippocampus damage can result in anterograde amnesia which is the loss of ability to form new memories. Someone who sustains an injury to the hippocampus may have good memory of his childhood and the years before the injury, but relatively little memory for anything that happened since.
Hypothalamus is a kind of master control center for emotion and many basic motives. The hypothalamus affects behaviors as diverse as sex, rage, body temperature, hormone release, eating and drinking, sleep, waking, and emotion. Damage to the hypothalamus can cause rapid weight gain. A person with a dysfunctional hypothalamus can have an appetite that is never satisfied, leading to over eating. The damaged hypothalamus can interfere with losing weight.
Cerebellum which looks like a miniature cerebral cortex, lies at the base of the brain. Cerebellum primarily regulates posture, muscle tone, and muscular coordination. The cerebellum also stores memories related to skill and habits. Without the cerebellum, tasks like walking, running, or playing catch become impossible. The first symptoms of a crippling disease called spinocerebellas degeneration are tremor, dizziness, and muscular weakness. Eventually victims have difficulty merely standing, walking, and feeding themselves.
Damage to the cerebellum can lead to: 1) loss of coordination of motor movement (asynergia), 2) the inability to judge distance and when to stop (dysmetria), 3) the inability to perform rapid alternating movements (adiadochokinesia), 4) movement tremors (intention tremor), 5) staggering, wide based walking (ataxic gait), 6) tendency toward
