Abstract: A non-motive system for enabling a person to carry out a function includes circuitry (4) (6) (8) (10) (12) (18) (20) designed to detect evoked-response potentials as a result of stimuli presented to the person. Each element of the stimulus corresponds to an external factor or function, so that the person attending to a particular element may communicate his desire that the external factor or function corresponding to that element be carried out merely through the detection of his brain wave response to the stimulus. The brain wave response is detected by electrodes (4), conditioned, and correlated with a precalibrated set of response template signals to derive the element attended by the subject, and thereby cause the indicated factor or function to be carried out.

Abstract: In order to determine defective magnocellular pathway in the visual system of a subject (3), a series of patterns of spatially varying light intensity, such as checkerboard patterns, are presented to a subject's eye (3). Each pattern provides a different degree of contrast between areas of varying light intensity. The display (5) of each checkerboard pattern is alternated with the display of its inverse pattern at a frequency between approx. 0.5 Hz and 15 Hz. The response of the eye (3), such as the visually evoked potential (9), is measured as the pattern is being displayed (5). The measured responses are compared (19) to a predetermined range of standard/normal responses for the given displayed patterns. Measured responses falling outside of the predetermined range of standard/normal responses indicate a magnocellular pathway defect, and hence dyslexia.

Abstract: An audiometric screening apparatus (10) and associated method provides fast, low-cost, noninvasive screening of a subject's hearing. The apparatus includes a signal processor (16, 54) for generating a stimulus signal and a probe (18, 56) electrically coupled to the signal processor and insertible in a subject's ear. The probe (18, 56) includes a transmitter (20, 58) to transmit the stimulus signal into the ear and a receiver (20, 60) for receiving a first response signal from the subject's ear. An electrode (24), electrically coupled to the signal processor (16, 54), is attached to the subject's scalp for sensing a second response signal. The signal processor (16, 54) processes the first response signal to provide an evoked otoacoustic emission signal and processes the second response signal to provide an auditory evoked potential signal.

Abstract: A frame (1) with driving members (9-11) for translating and/or rotating an assembly (4) movably mounted in said frame along one of the three planes defining the space. A unit for mechanically controlling said driving members is arranged to enable the stationary patient on the movable assembly (4) to be exposed to a moving elementary stimulation having monotonic space-time characteristics with a speed- and/or acceleration-adjustable profile, by translation and/or rotation thereof along at least one of said three planes of the space. The device further includes a processing unit for digitising waves sensed by at least some of the electrodes of an electrophysiological helmet on the patient's skull, and for finding therein evoked potentials that match the profile of the elementary stimulation. Real-time data on the functioning of at least one part of the vestibular system may thus be obtained.

Abstract: Accommodation training apparatus is modified to include electroencephalography apparatus (142, 146) for monitoring the patient's brainwaves. This permits a patient to be trained to enter, and to remain in, the alpha state, even with the eyes open and with something to look at. A two-dimensional CCD matrix (124) is used to receive reflected-back radiation from the eye (100). A computer (148) is connected to the matrix and permits the patient to be trained for correction of conditions such as strabismus, nystagmus and eccentric fixation by identifying whether the patient's eye is moving or whether the patient's state of accommodation is changing. An LCD matrix (132) is used to present variable visual information to the patient's eye. This facilitates training the patient for dichotic learning. Advantageously, electromyography apparatus (142, 146) is used to monitor the tension of one of the patient's muscles, advantageously the frontalis muscle.
