The interaction across the border between mind and associative cerebral cortex occurs only when there is a high level of diversified activity the brain's neural associative mechanism, when the level of activity is very low, such as in anesthesia or coma, the individual is unconscious and therefore is incapable of affecting brain processes. The physical world is not closed, as it may be influenced by mental states and in turn have an impact on them. Adapted from Pascual F.
