Imagination relies on an ability to differentiate between what’s real and what’s not — and now, scientists have uncovered potential brain mechanisms that make this distinction possible. These, they hypothesize, may be significant in conditions like schizophrenia, which can affect people’s perception of reality.
A paper published June 5 in the journal Neuron explored these mechanisms. Scientists know from previous research that a specific brain region — the fusiform gyrus, a large ridge that runs across two lobes of the brain — is active both when you see something in reality and when you imagine something, first study author Nadine Dijkstra, a neuroscientist at University College London, told Live Science.
“But what we found was that the activity levels in that region predicted whether or not you think something is real, irrespective of whether you see or imagine it,” she explained.
