Texture stimulus presenting apparatus, magnetic resonance imaging apparatus and magnetoencephalograph including the same, and brain function measuring method
Provided is a texture stimulus presenting apparatus to be used when measuring a texture perception of a subject by detecting a change of a magnetic field in a brain of the subject. The texture stimulus presenting apparatus includes a light source configured to irradiate with light a specimen to be presented to the subject, and a control unit configured to control at least one of position of the light source, tilt of the light source, property of irradiation light from the light source, timing of irradiation, or surface morphology of the specimen facing the light source.
