Conventionally, it is impossible to detect an object to which a person feels a similar sense based on latent consciousness. Detection of an object to which a person feels a similar sense is realizable by a brain information processing apparatus using high-level brain activity information indicating a latent consciousness. The brain information processing apparatus has stored therein one or more pieces of brain information that includes brain activity information, which is information on a brain activation level, and object information, and includes: an accepting unit that accepts brain activity information an object information acquisition unit that acquires one or more pieces of object information associated with one or more pieces of brain activity information that is approximate to the brain activity information to the extent of satisfying a predetermined condition and an output unit that outputs the object information acquired by the object information acquisition unit.
