Abstract
A stimulus presentation device that provides stimuli to the test subject in a computer-based random manner during brain function measurement to investigate brain functions based on the response from a test subject exposed to stimuli. The invention can present stimuli to the test subject for measuring brain functions, eliminating time-dependent disturbance factors that may cause the test subject to become tired of the stimuli and accustomed to the repetition of stimuli during the test.
Claims3
A stimulus presentation device (including a monitor, speaker, or screen) for measuring brain functions;
- the device comprising (for presenting multiple stimuli within a predetermined period):
- a means of randomly changing the sequence of stimuli presented using a computer;
- a means of randomly changing the intervals or durations of time for presenting said stimuli using a computer;
- and
- a means of controlling the stimulus presentation device so as to present the stimuli in said randomized sequence.
2 more elements
A device to measure brain functions comprising:
- a means of presenting stimulus (including a monitor, speaker, or screen) to arouse the sense of sight for such a short time that the test subject cannot visually recognize said stimulus;
- a means of displaying multiple stimuli including said stimulus arousing the sense of sight so that the test subject can visually recognize the stimuli;
- a means of recording said stimulus information;
- and
- a means of acquiring and recording brain function information as a function of time during said stimulus presentation.
