<p><P>PROBLEM TO BE SOLVED: To provide a brain function measurement instrument which can specify a cerebral activity region and can obtain high spatial resolution. <P>SOLUTION: The brain function measurement instrument 1 includes one light source 6 which emits near infrared light L towards a brain 5 and two or more light receiver arrays 3 which detect the near infrared light L which transmits the brain 5. Each of the light receiver arrays 3 is formed on a scalp 2, and the light source 6 is arranged within the oral cavity 4 and is therefore provided on the opposite side through the light receiver array 3 and the brain 5. An optical fiber which adjusts the emitting direction of the near infrared light L, is provided in the light source 6. In the optical fiber, the direction of an emission part is adjusted so that the near infrared light L may be emitted towards the brain 5. Moreover, a lens of the shape of a spherical surface, which radially diffuses the near infrared light L having been emitted from the outgoing part, is attached to the emission part of the optical fiber. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
