The device of the present invention can automatically extract words under accurately controlled set conditions. A word presenting means presents words to a subject, a biological activity measuring means measures the biological activity in the subject, and a calculation means receives a biological activity signal from the biological activity measuring means and calculates time from presenting the words until detecting a biological activity by the subject accompanied with the word. The calculation means is equipped with a word database where word data indicating words are stored and can be presented to the subject, a category data of the words and attribute data of the words are related and also stored, respectively, and a word extractor to search the word database and to extract the word data belonging to or relating to a predetermined category, and, satisfying predetermined word attribute, based upon the search conditions. The word presenting means presents a portion of or entire words indicated by the word data extracted by the word presenting means to the subject.

Language processing function measuring device

A visual training deviceincluding: a screen arranged facing a subject H having visual impairment; a line of vision detection unit that detects a line of vision of the subject H and outputs line of vision signals indicating the line of vision; a visual field data storage unit that stores visual field data indicating the visible area ARand the area of visual impairment ARof the subject H; and a screen control unitthat, on the aforementioned screen, moves the visible area ARspecified based on the aforementioned visual field data in correspondence to the movement of the line of vision of the subject H specified by the aforementioned line of vision signals. The display format of the visible area ARor a region including the vicinity thereof, is displayed different from the display format of the other region. By doing this, an attitudinal barrier of the person with visual impairment, the subject, can be removed, and the visual training device can allow easy training to be provided.

Visual training device and visual training method

A method of solving magnetoencephalographic and electroencephalographic inverse problems provides better grouping of moments of equivalent current dipoles than conventional methods. Locations of dipoles are fixed based on information using fMRI or the like. The magnitudes and orientations of the dipole moments are adjusted to fit magnetic fields and/or electrical potential distributions produced by the dipoles to magnetoencephalographically and/or electroencephalographically measured data. The method also includes grouping the dipoles in two stages, using the correlation coefficient of the magnitudes of the dipole moments as a criterion.
