Question

Rory and dory are identical twin rats. the lateral area of rory's hypothalamus was destroyed in a tragic exercise wheel accident. the ventromedial nucleus of dory's hypothalamus has an electrode implanted in it that is constantly stimulating that part of her brain. this situation has existed for a week now. how does rory's weight compare to dory's?

Answer 1

Both Dory and Rory are both extremely underweight. When rats' stomach or cerebral cortex is removed it increases the hamster wheels which occurs when rats were deprived of food and also water and vitamin B for example thiamine.
It increases the chances of finding food for the rats.
