Visual evoked potentials in hemiparkinsonism
Electroencephalography and Clinical Neurophysiology, 1981Abstract Visual evoked potentials (VEPs) were recorded bilaterally from the parietal areas in patients with hemiparkinsonism. VEPs recorded over the hemisphere contralateral to the side of parkinsonian symptomatology showed diminished maximal amplitude of secondary components and increased peak latency of an early positive component (P 100 ). After a

The visual evoked potential (VEP) is primarily a relatively large, positive polarity wave generated in the occipital cortex in response to visual stimulation. It measures the conduction time of neuronal activity from the retina to the occipital cortex and is used clinically as a measure of the integrity and function of that pathway.

Under the pathological conditions, the VEP may show changes in amplitude, latency, or waveform in one or more of its components. The major advantage of the pattern reversal VEP over the flash VEP lies in smaller variability in the waveform and latency of its components in the healthy population. The flash VEP is, however, particularly useful to infants

The visual evoked potential (VEP) is a measure of time locked visual cortical activity, measured at the scalp, to a controlled stimulus that enables objective assessment of the integrity of the retino‐cortical visual pathway. VEP waveform characteristics and morphology are dependant upon signal generators, in response to pattern or flash, achromatic or
