Abstract:
1. A brain state support apparatus comprising: an electrical stimulator configured for stimulating an acupoint in the human body in a region adjacent to the center of the side of the palm of the left hand between the first and second joints of the thumb, and including a first electrical stimulating portion adapted to stimulate the acupoint with an electrical signal of a first frequency of 3 Hz and a second electrical stimulating portion adapted to stimulate the acupoint with an electrical signal of a second frequency of 10 Hz, in order to change the amount of the total hemoglobin and the amount of oxygen saturation in the human body, and a retainer portion adapted to releasably hold the first and second electrical stimulating portion in engagement with the acupoint; a light detector configured for detecting light information, the light detector having a light emitting section for irradiating the human body with a light at a predetermined region, and a light receiving section for receiving and sensing a light emitted from the light emitting section at the predetermined region and passing through the interior of the human body; and a processor configured for controlling the electrical stimulator and the light detector, said processor including: wherein when the electrical signal of the first frequency is applied to the acupoint, the oxygen metabolism in the frontal lobe increases relative to the oxygen metabolism in the frontal lobe in the absence of an electrical signal, and when the electrical signal of the second frequency is applied to the acupoint, the oxygen metabolism in the frontal lobe decreases relative to the oxygen metabolism in the frontal lobe in the absence of an electrical signal, with the oxygen saturation being reduced relative to the oxygen saturation in the absence of an electrical signal with the electrical stimulator adjusted to stimulate the acupoint with the electrical signal of the second frequency, and the total hemoglobin and the oxygen saturation being increased relative to the total hemoglobin and the oxygen saturation in the absence of an electrical signal with the electrical stimulator adjusted to stimulate the acupoint with the electrical signal of the first frequency.
