Claim One:
1. An apparatus for examining a pathological interaction between different brain areas, comprising: a stimulation unit configured to successively administer identical stimuli to a patient, wherein the stimuli stimulate neurons of the patient in the brain areas to be examined; a measuring unit configured to record measured signals which reproduce a neural activity of the stimulated neurons; and a control and analysis unit configured to control the stimulation unit and analyze the measured signals, wherein the control and analysis unit is configured such that the control and analysis unit: controls the stimulation unit to administer the stimuli to the patient; and transforms the measured signals into a complex plane, examines the distribution of phases of the measured signals recorded by the measuring unit in the complex plane as a response to the stimuli administered to the patient, and determines the probability with which a phase distribution differs from an equal distribution to determine whether a pathological interaction between the different brain areas is present.
