A lot of people discount Jayne's theory for the inaccuracy regarding its assertions about the physical mechanisms, namely that specific modules in one half of the brain talk across the corpus callosum to specific modules in the other half. But IMO they're throwing the baby out with the bathwater. What I haven't seen yet are investigations into the nature of self-awareness and agency assuming that his theory holds water on the mental aspects. Studies have shown that we make decisions whole seconds before we are conscious of our coming to a conclusion. Could this not be some remnant of the potential fact that our internal decision processes are based around a similar mechanism as what he proposes? The only difference is that we think that "voice" telling us what to do is ourselves, and not some imposition from outside.
