On‐line Data Acquisition - Abstract
The human cortical evoked response to sensory stimuli has been recognized as a valuable aid in clinical studies and diagnoses. The stimulus modalities commonly used are visual, auditory and somatosensory. In this study, we have developed a non-invasive measure of the dynamic response of the human central nervous system by subjecting the patient to a broad variety of stimulus parameters. Our aim has been to optimize the amount of information extracted from single evoked responses in order to maintain the test duration within reasonable limits. Studies to date suggest that a protocol incorporating Wiener filtering, along with computer control of stimuli, provides a useful method for quantitatively extracting CNS response patterns to sensory stimuli. With the additional development efforts in progress, this procedure should provide further information for the clinical assessment of neurological disease states.

- Abstract
Based upon a three-dimensional plot (response plane) representing a condensation of human sensory evoked potential data obtained from a paired stimulus protocol, a study was undertaken to investigate electrophysiological changes following sodium valproate administration in subjects with photosensitive epilepsy. Initial results in two patients and two normal subjects suggest that the measure is reproducible and sensitive to electrophysiological changes accompanying anticonvulsant administration.

- Abstract
Visual evoked potentials (VEPs) to intermittent flash trains of various stimulus frequencies (VEP-T) were studied in 10 normal subjects and in 10 patients with photosensitive generalized seizures, 5 on medication and another 5 subjects without medication. In the normal group, early negative peaks were consistently demonstrated at 71 +/- 8 msec for monocular stimuli and 67 +/- 9 msec for binocular stimuli, regardless of different frequencies of stimuli. An oscillatory potential, poststimulus continuation of the oscillatory activity and damping out within 100 msec followed the initial peaks. The RMS values of the response epochs were stable and demonstrated consistent temporal changes at each stimulation frequency. In photoconvulsive seizures, the responses were facilitated with most marked changes over the second and third 125 msec epoch of the VEP-Ts with late slow negative deflections in some cases. These changes were pronounced in patients who were not taking anticonvulsant medication, but were not significantly different than controls in patients whose seizures were controlled with medication. It is suggested that the VEP-T is a more effective technique than single flash stimuli in consistently identifying early significant peaks and demonstrating neuronal excitability changes within the visual system.
