Over the phone, the men hatched a plan to return the brain to Einstein's. A cascading series of bodily failures, heatstroke can cause dizziness, nausea, confusion, and cell death. It is in the occipital lobe of the primary cerebral cortex, which is in the most posterior region of the brain. The human brain can generate about 23 watts of power (enough to power a lightbulb). Advertisement. It serves as a relay station, passing messages back and forth between various parts of the body and the cerebral cortex. The cerebellum (“little brain”) is a fist-sized portion of the brain located at the back of the head, below the temporal and occipital lobes and above the brainstem. Cerebral hypoxia. Low blood sugar causes people to feel irritable, confused and fatigued.
