What's going to happen? Cognitive functions of a genuine motor cortex

When we are about to cross a road and think about waiting for the next car or not, we have to coordinate two predictions at the same time. We anticipate both how things will change in our environment and how we will change things in our environment. However, brain activation shows that even if we do not plan to cross the road we still activate the same brain regions – those for action planning. Brain imaging addresses this phenomenon and tries to tackle the question as to why some cognitive functions make use of genuine motor regions of the brain.
