Abstract: A biosignal measurement unit and a condition analysis system. In a side view from a first earmuff of a biosignal measurement unit, when a straight line parallel to a downwardly extending direction of a headband and passing through a centroid of a plane region formed by the first earmuff is defined as a first reference line, and a straight line orthogonal to the first reference line and passing through the centroid is defined a second reference line, a first position is located at a position forward of the first reference line and downward of the second reference line.

Abstract: An electroencephalogram analysis device includes a signal acquisition unit that acquires a time series of electroencephalographic signals of an analysis subject, and a computation unit that obtains an intrinsic frequency correlated with a movement intention of the analysis subject based on a frequency characteristic related to the time series of the electroencephalographic signals of the analysis subject during rest.

Abstract: An electroencephalogram decision system determines, when finding electroencephalogram information representing an electroencephalogram obtained by an electrode unit placed on a region of interest that forms part of a subject's head satisfying a predetermined condition, that a target electroencephalogram, which is an electroencephalogram with a characteristic variation, should have been produced. The predetermined condition is selected from of detection conditions including a first type of condition and a second type of condition. The first type of condition specifies that a decision should be made, based on a component falling within a single frequency band included in the electroencephalogram represented by the electroencephalogram information, whether or not the target electroencephalogram has been produced.

Abstract: A finger exerciser includes: a frame on which a palm of a subject to be put; a movable section; a first fixing element; and a second fixing element. The movable is configured to move a first finger group of a subject. The first fixing element is configured to fix a position of the first finger group to the movable section. The second fixing element is configured to fix a position of a second finger group to the frame and has a band-like member including at least two attachment parts apart from each other in a longitudinal direction of the band-like member. The band-like member is attached to the frame at the attachment parts and includes a holder whose location to the frame is changeable. The band-like member is configured to hold the second finger group in a state where the band-like member is attached to the frame.
