A 2000 study by the UCSD School of Medicine and the Veterans Affairs Healthcare System in San Diego, used functional magnetic resonance imaging (fMRI) technology to monitor activity in the brains of sleep-deprived subjects performing simple verbal learning tasks. The study showed that regions of the brain’s prefrontal cortex (PFC) displayed more activity in sleepier subjects. Depending on the task at hand, in some cases the brain attempts to compensate for the adverse effects caused by lack of sleep. The temporal lobe, which is a brain region involved in language processing, was activated during verbal learning in rested subjects but not in sleep deprived subjects. The parietal lobes, not activated in rested subjects during the verbal exercise, was more active when the subjects were deprived of sleep. Although memory performance was less efficient with sleep deprivation, greater activity in the parietal region was associated with better memory.

Yes it will. Not only does lack of sleep inhibit memory formation but it can harm your immune system. Although an "all nighter" is okay every now and then it should not be a way of life. It will actually hurt your performance and can lead to sleep problems. Work on planning your time better so that you can get at least 6 hours of sleep at night. Try to catch up on sleep on weekends.

ofcourse! 3-4 hrs of sleep are usually for old peolple. You are a universal strudent , u got a lot to study, sleep replenishes ur energy, stamina , and also releases some of ur anxiety. An afternoon sisesta is enough as it sharpens ur memory.

sleeping 3-4 hours would affect ANYBODY in a negative way, no matter what you do. I cant imagine sleeping so little and trying to concentrate in class and studying

Yes, it is not recommended. Lack of sleep over a long period of time is dangerous.

definitely, it will make it harder and harder to stay awake in class, and u'll probably start getting worse grades cuz u wont be able to concentrate as well, it kinda has the same affect as doin drugs (altho not as extreme)

Yes, and it's a big negative effect. On a regular basis, that is.
