ask.dr.b@gmail.com (Dr. Dave Brodbeck) — Fri, 01 Aug 2008 12:51:20 -0400

Jenna (I hope I spelled your name correctly...) wants to know how your brain controls your fingers. This is a really neat question, and because I am a psychologist, I did not have to ask anyone but myself. One of the very neat things about this is that the left half of your brain controls the right side of your body. Oh, and even though it feels like you move as soon as you want to, it takes at least 300 msec before anything actually happens in your fingers. The key to the whol thing is a neurotransmitter called acetylcholine.
