Ben, Yea, as I understand things, the conduction velocity is determined by physical characteristics of axons - diameter, membrane thickness, etc. - things that are unlikely to change with temperature. If this is so, then the *differences* in times with body temperature, alcohol, etc, *must* be coming from changes in the computational elements.
Did you see Matt's times - some less than 200ms. Subtracting off the time for the pulses to get to his fingers, either he is a midget, his conduction velocity is high, or things must be REALLY fast behind his eyeballs.

Simply institute a six hour workday. That will easily create enough new jobs to bring back full employment. ------------------------------------------- AGI Archives: https://www.listbox.com/member/archive/303/=now RSS Feed: https://www.listbox.com/member/archive/rss/303/21088071-f452e424 Modify Your Subscription: https://www.listbox.com/member/?member_id=21088071&id_secret=21088071-58d57657 Powered by Listbox: http://www.listbox.com
