One brain area that has emerged as playing a key role in discriminating imagination from reality is anterior prefrontal cortex. This is a region right at the front of the brain, just behind your forehead. It is an area that, in relative terms, is roughly twice as large in the human brain as in even our closest non-human cousins, the great apes. It is thought to be among the last areas to achieve myelination, the neurodevelopmental process that continues into adolescence and enables nerve cells to transmit information more rapidly, allowing for more complex cognitive abilities. As such, although the functions performed by this area are not well understood, they have generally been considered likely to be among the “higher” levels of human complex cognition.
