How long can you go without sleep before hallucinating?

The longest recorded time without sleep is approximately 264 hours, or just over 11 consecutive days.

He ran down all the ways in which sleep deprivation hurts people: it makes you dumber, more forgetful, unable to learn new things, more vulnerable to dementia, more likely to die of a heart attack, less able to fend off sickness with a strong immune system, more likely to get cancer, and it makes your body literally …

Can you regrow brain cells?
