  • Patent number: 10820823
    Abstract: A more practical method for evaluating an inhibitory circuit applicable to a living body, and the use thereof. Herein the action of an inhibitory circuit on an excitatory circuit is evaluated on the basis of attenuation of the brain activity produced by activation of an excitatory circuit by the input of an inhibitory circuit by performing a step for inputting an inhibitory circuit by applying a second trigger in advance of a first trigger to an excitatory circuit activated by a first trigger which is a stimulus or challenge.
