[PD-ot] how low (latency) can you go?

[B. Bogart]

I just have to chime in here,

I read a book about 5 years ago that talked about a lag of consciousness
as being as much as 250ms. Here is a contemporary study that shows that
it takes about 100ms to even perceive something happening.

Check out Libet:

http://cornea.berkeley.edu/pubs/161.pdf

This is some *very* interesting research!

The original book talk about a special spike in the nerve signal that
served as the time marker for an event. The jist is that your
consciousness projects itself into the past, so that things seem to
happen immediately, when they are really happening 100ms before we
notice...

I believe it was a Evan Harris Walker book that referred to the work of
Libet.
