sync2brain commercializes a novel technology that for the first time enables effective, personalized therapy for patients with stroke or depression - with much less side-effects compared to conventional therapy. Their bossdevice combines devices for electroencephalography (EEG) with devices for transcranial magnetic stimulation (TMS) of the brain. It synchronizes the stimulation to the individual brain state making TMS most effective. The bossdevice MEDICAL will be certified as a medical device in the coming months. A research variant of the device (bossdevice RESEARCH) is already avaible. The long-term goal is to establish bossTMS therapy as a standard procedure for the treatment of stroke, depression and other neuropsychiatric disorders.
