Roland Piquepaille writes "Medical professionals have always dreamt of mapping the activities of the human brain in real time -- 'touching' instead of looking. Of course, modern brain scanners, such as MRI, already offer sophisticated and passive views into the human brain. But now, IST Results reports that a young Finnish company, Nexstim, has developed a non-invasive brain scanning and stimulation system called navigated brain stimulation (NBS). This system "guides the precise delivery of targeted transcranial magnetic stimulation (TMS) pulses to discrete brain areas." It is today the only device available for accurate prediction of the TMS stimulus location and dose within the human brain and is already in use in 20 hospitals and brain research centers worldwide.
