The Modular Model of the Brain Is Probably Wrong

Standard

Paul Cisek and other researchers have proposed a whole brain parallel processing model.  New research seems to support it!

“But what if we instead considered the possibility that all brain functions are distributed across the brain and that all parts of the brain contribute to all functions?”

“The problem can be illustrated by a recent study which found that the psychedelic drug LSD can disrupt the modular organisation that can explain vision. What’s more, the level of disorganisation is linked with the severity of the the “breakdown of the self” that people commonly experience when taking the drug. The study found that the drug affected the way that several brain regions were communicating with the rest of the brain, increasing their level of connectivity. So if we ever want to understand what our sense of self really is, we need to understand the underlying connectivity between brain regions as part of a complex network.”
