Because we can’t possibly absorb every single stimulus, our brain lets some of these signals filter through to our consciousness while others don’t.
But where specifically in the brain does that filtering take place? If somewhere in the brain exists the gateway to consciousness, which part of the brain functions as the gatekeeper?
Researchers at the University of Michigan Medical School set out to answer this question. Their study, published Tuesday in Cell Reports, suggests they’ve found the answer.
