Philosophers of mind have been debating for many years whether there are subjective properties of experience --- it is sometimes said that those subjective properties are what make it true that there is "something it's like" to have an experience. (Have a look, for an example, at Thomas Nagel's "What Is it Like to Be a Bat?", Philosophical Review, pp. 435-50.) Well the article in Time magazine (linked from the title of this post), called "My Nose, My Brain, My Faith," reports on some new research suggesting that there may be something it's like to believe and to disbelieve, at least insofar as the brain regions associated with believing and disbelieving also seem to be active when we respond positively or negatively to smells. But philosophers have not traditionally thought that these states have a subjective character.
