SensoDetect has developed a method for objective neurophysiological decision support for diagnostics, primarily in psychiatric health care and forensics. The technology underlying SensoDetect’s test instrument, SensoDetect® BERA, is based on brainstem audiometry and is the result of extensive research at Lund University.
