Feeling a little bit tired? Did you pull an all nighter to make that deadline? While you may be feeling weak and drowsy, your brain has just gone into overdrive.

A new study prods human brains with electrical impulses at different lengths of sleep deprivation and measures how much activity the brain responds with.

Scientists have found that this increase in activity is what leads epileptics to be more susceptible to seizures and depressed people to feel better after skipping a night of sleep.

Seems like an extreme measure to feel happy, how bout some chocolate, or maybe a song?
