Attention in humans is quite a varied thing. Children notice different 
things than adults do. People taking acid might fall in love with their 
bathroom toilets and spend the whole trip in the bathroom, while a 
seven-foot-tall tattooed skinhead in a knit minidress might escape notice 
in some sections of New York City.

What's the chemical action going on here (LSD notwithstanding)? Is there a 
chemical released by some part of the brain that, when present, causes one 
to pay more attention to details and, when absent, causes one to ignore 
certain details? What's been written on this subject?
