The method for inducing sleep by a sleep inducing system includes acquiring brain signals of a user as sleeping time passes; calculating a functional connectivity value between two channels for each frequency based on the acquired brain signals and performing brain network analysis; determining the stage of sleep of the user based on features of the analyzed brain network; determining a target frequency according to the determined stage of sleep and generating a binaural beat with which the brain signals of the user are induced to the target frequency; combining the generated binaural beat with ASMR information; providing the combined auditory stimulus information to the user; and determining whether the current stage of sleep of the user is maintained at an appropriate proportion with respect to total sleep time, determining whether or not to induce the next stage of sleep, and performing feedback according to the result of determination.

Method and system for inducing sleep

A method of monitoring an anesthesia and consciousness depth through brain network analysis by a computing device according to the present disclosure includes: acquiring a user's brain signals extracted during anesthesia; performing pre-treatment to the acquired brain signals to be suitable for brain network analysis; calculating a functional connectivity value between two channels for each frequency based on the pre-treated brain signals and performing brain network analysis; determining an anesthesia and consciousness depth of the user based on features of the analyzed brain network; and providing the determined anesthesia and consciousness depth of the user through a user interface.
