1. A motor teaching system for detecting cerebral activity of a subject and supporting motor training of the subject, comprising:
an operation device configured to teach motion to the subject in accordance with a predetermined motor pattern by guiding movement of a movable part of a body of the subject;
a measurement device configured to acquire a cerebral activity signal, by measuring the cerebral activity of the subject; and
one or a plurality of computers configured to control an operation for teaching the motor pattern by the operation device and configured to classify the cerebral activity of the subject into one of a plurality of classes including a motor imagery class by decoding the cerebral activity signal,
wherein the one or the plurality of computers output whether the cerebral activity of the subject during a teaching period of the motor pattern is classified into the motor imagery class, as a result of decoding the cerebral activity signal acquired by the measurement device during the period in which the operation device is caused to execute the operation for teaching the motor pattern,
wherein the one or the plurality of computers hold information indicating a plurality of transition patterns of cerebral activity of the motor pattern from prior to teaching to during teaching,
wherein the one or the plurality of computers specify a transition pattern of the subject from the plurality of transition patterns,
wherein the one or the plurality of computers determine an evoking content to be performed to the subject prior to teaching of the motor pattern, such that the cerebral activity of the subject during the teaching period of the motor pattern is classified into the motor imagery class, based on the specified transition pattern of the subject,
wherein the one or the plurality of computers output the determined evoking content, prior to teaching of the motor pattern,
wherein the plurality of transition patterns of cerebral activity comprises the following four patterns:
(A) cerebral activity during the motor teaching period is in a motor imagery state when cerebral activity prior to motor teaching is in the motor imagery state; whereas cerebral activity during the motor teaching period is in a rest state when cerebral activity prior to motor teaching is in the rest state;
(B) cerebral activity during the motor teaching period is in the rest state when cerebral activity prior to motor teaching is in the motor imagery state; whereas cerebral activity during the motor teaching period will be in the motor imagery state when cerebral activity prior to motor teaching is in the rest state;
(C) cerebral activity during the motor teaching period is in the motor imagery state, irrespective of the class of cerebral activity prior to motor teaching; and
(D) cerebral activity during the motor teaching period is in the rest state, irrespective of the class of cerebral activity prior to motor teaching.
