摘要:
A biosignal measurement device is proposed which can improve measurement accuracy without forcing an excessive burden on subjects.A biosignal measurement device used for measurement of a biosignal in a head includes a support that can support the head, and an electrode provided to the support. The electrode has a plurality of teeth each including an annular portion in which a pair of linear members having conductivity are formed in an annular shape, and a rod-like portion in which the pair of linear members are wound in opposite directions and formed in a rod-like shape. The rod-like portion in each of the plurality of teeth is directly or indirectly fixed at one end to the support.

A biological signal measuring equipment used in a measurement of a biological signal in a head portion, has a jaw contact portion that comes into contact with a forehead; an occiput contact portion that comes into contact with an occiput; and a supporter that is interposed in a front and rear direction of the head portion and is supported by the head portion by using the jaw contact portion and the occiput contact portion as ends. The biological signal measuring equipment performs the measurement in the same manner as the case of measuring a wave motion of a short period, even in the case of measuring the wave motion of a long period generated in a head portion.

To provide a simple and low-invasive method for obtaining information on a biorhythm of an individual organism. Provided is a method for obtaining information on a biorhythm of an individual organism based on variations over time in an expression level of a clock gene in a hair follicle cell of the individual organism. According to this method, a phase shift of the biorhythm of the individual organism can be detected by preparing a plurality of times about the individual organism and conducting a collation. Further, a phase shift of the biorhythm of the individual organism can also be detected by collating an expression level of the clock gene at a predetermined time with the molecular clock table.

There is provided a method that achieves the prediction of a biological rhythm with high precision while minimizing the number of times a biological specimen is collected from a subject. There is also provided a method for predicting a biological rhythm of a subject on the basis of time series expression level data obtained by measuring expression levels of two clock genes in biological specimens collected from the subject three times within 24 hours, the clock genes having different phases of circadian cycles of a change in expression levels. In this method for predicting a biological rhythm, a biological rhythm can be predicted with particularly high precision by collecting a biological specimen from a subject three times within 24 hours at eight-hour intervals.
