LED Taillights on the Way
are about to become high tech. Two major pathways lead from our eyes
to our brains. The faster m-pathway transmits info about motion and
triggers fast reactions, while the slower p-pathway registers generalities.
The m-pathway tells you to duck when a rock is coming toward your head,
while the p-pathway tells you "there's a red thing ahead" when a taillight
comes on. Researchers are developing an LED cluster that operates in
50 ms pulses in a way that stimulates the m-pathway for a quick reaction,
while simultaneously the more rational p-pathway signals allow your
brain an opportunity to create a controlled response.
