An interesting New Scientist article that talks about the links between dopamine, time-perception and ADHD, as well as other mental illnesses:
“Rubia believes this is evidence that faulty time perception causes the major symptoms of ADHD, by making children perceive even short periods of inactivity as inordinately long and boring. Because novelty-seeking and risky behaviour increase dopamine levels, children with ADHD may be become hyperactive as a way of “self-medicating” with dopamine.” — Time moves too slowly for hyperactive boys
It hadn’t occurred to me that time-perception was something the brain did, although it’s obvious now that I think about it. Brains and brain chemistry are quite fascinating… They do so much stuff that we just don’t think about.
