nutmegs reviews – StumbleUpon

Another steal stolen from resident science buff Nutmeg. This one caught my light-sensitive eye as it sounds EXACTLY like my experience with photic sneezing – so much so that I’ve even dropped a no-doubt laughable note in to the department at Brown about it:

“These cells operate like a light meter on a camera. They tell the brain to constrict the pupil based on the amount of light registered over time… Until now, we didn’t know if these cells were adaptive to lighting conditions… Now we know that they are. Compared with rods and cones, they’re glacially slow and they don’t adjust their sensitivity as completely. But they do behave in similar ways.”
