ABSTRACT:
In electrophysiology, methods of testing a subject's neural mechanisms of learning and memory in order to quantitatively diagnose the subject's brain dysfunction require specified conditions or stimuli to evoke his electrical brain activity, which are his response or non-response to the stimuli. These evoked responses are quantitatively interpreted by challenges which specify analytic protocol. A test using letter reversal conditions identifies a subject's problems relating to pattern reversal and perception. A test involving figure-ground condition in which a primary stimulus is obscured with secondary stimuli indicates a subject's ipsimodal and cross-modal inhibition. A test using a standard-interruptive condition, in which a series of standard and interruptive stimuli are alternated, indicates a subject's conditionability, sensitization and recovery cycle.
