What is Movement/Motion?

Motion and Movement has different meanings in most fields. In physics, they describe how energy is transferred from potential to kinetic. In politics, they could describe a group of people that come together due to a similar set of beliefs. You can have movements of physical things and movements of non-physical things, for example, the movement of ideas. I’m interested in movements in the brain and how they affect the physical world and how the physical world affects the brain.
