Seeing and imagining use similar brain machinery. New research reveals the brain circuit that identifies what is real, which may help scientists understand conditions such as schizophrenia.

So it’s beginning to look like the brain has a dedicated internal supervisor, that label sensory impressions “real-world”. And it can go wrong – and you assume a voice in your head has come to you from outside.

A promising line of research. But (like Geology and Darwinian evolution) I’m waiting to hear it falling foul of religious nutters on school boards because it contradicts somebody’s “reality”.
