DEVICE FOR MEASURING BRAIN ACTIVITY STATE

摘要

PROBLEM TO BE SOLVED: To provide a device for measuring a brain activity state capable of securing the accuracy of data of the brain activity state of a subject for odors when the subject smells two or more odors one by one.

SOLUTION: The device for measuring the brain activity state includes: an MRI or NIRS to acquire the data of the brain activity state of the subject; a non-magnetic supply pipe that forms a route for supplying a prescribed smell to the position of the subject's nose in the MRI or NIRS; a deodorant means that eliminates the prescribed smell existing near the subject's nose; and an excretory duct that exhausts air existing in the position of the subject's nose.
