Single gene causes stinging cell to lose its sting

Hopkins Scientists Clock The Speed Of Comprehension

Researchers from Johns Hopkins Medicine discovered that it took a volunteer patient about 250-300 milliseconds to begin understanding a pictured object, and another 250-450 milliseconds to fully comprehend its meaning. The study suggests that information accumulates gradually in the brain, rather than in a strictly all-or-none fashion.
