identity theory

Type physicalism (also known as Type Identity Theory, Mind-Brain Identity Theory and Identity Theory of Mind) is a theory, in  philosophy of mind, which asserts that mental events are type-identical to the physical events in the brain with which they are correlated. The thesis of type physicalism is that mental event types (for example, pains) are identical, perhaps contingently, with specific physical event types in the brain (for example, C-fiber firings).

The identity theory (IT) of mind is standardly understood to be the claim that every mental property is identical with some physical property.
