Philosophy of mind is the branch of philosophy which deals with the mind and its properties, including conciousness, mental processes and events.
Philosophy of mind often overlaps with psychology, cognitive science and neuroscience in general. Whereas psychology and the natural sciences are concerned with the specifics of mental states and brain functions, philosophy of mind is responsible for the larger questions of the nature of mind itself, its relationship to the physical world and where it belongs in a proper ontology.
In recent times, the problem of philosophy of mind has become heavily focused on data from the natural sciences with respect to the brain. It is now an area researched mainly by analytic philosophers and, partly because of its strong realtionship with the sciences, may be considered an area of analytic philosophy.
Concerns about the nature of mind with respect to ontology, such as the mind-body problem may also be considered part of metaphysics.
At the core of philosophy of mind is the mind-body problem, which is concerned with the relationship between the mind and the physical world.
