LED Taillights on the Way
Brake lights 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.
