Abstract: This disease diagnosis result determination device is provided with: a brain examination result determination unit that determines a result of brain examination concerning a second subject on the basis of medical checkup data concerning the second subject and a first learning result obtained by performing learning in advance of a relationship between medical checkup data concerning a first subject and a result of brain examination concerning the first subject; and a disease diagnosis result determination unit that determines a disease diagnosis result concerning the second subject.

Abstract: The behavioral tendencies of a system in which responses evoked by stimuli are measurable are determined by means of a method and apparatus for applying a train of paired stimuli to the system and measuring and analyzing the response. The first of each pair of stimuli (conditioning stimulus) is applied at randomly varying intensities and at a constant interval. The second of each pair of stimuli (test stimulus) is applied at a constant intensity and a randomly varying interval from its associated test stimulus. By appropriate analysis of the amplitude and latency of the evoked responses, important information about fatigue, refractory period, supernormal period, threshold and dynamical fluctuation can be determined.
