The electrophysiological assessment of visual function in Multiple Sclerosis
The assessment of vision is integral to the diagnosis and monitoring of patients with multiple sclerosis (MS). Visual electrophysiology, previously a critical investigation in patients with suspected MS, has in large part been supplanted by magnetic ...

The effects of glaucoma on the latency of the multifocal visual evoked potential [PDF]
To determine the effect of glaucomatous damage on the latency of the multifocal visual evoked potential (mfVEP).Monocular mfVEPs were recorded from a glaucoma group (n = 50) defined by a glaucomatous disc and an abnormal visual field and a control group (n = 47).

The magnocellular system has been implicated in the rapid processing of facial emotions, such as fear. Of the various anatomical possibilities, the retino-colliculo-pulvinar route to the amygdala is currently favored. However, it is not clear whether and

Omega-3 fatty acids modify human cortical visual processing--a double-blind, crossover study. [PDF]
While cardiovascular and mood benefits of dietary omega-3 fatty acids such as docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) are manifest, direct neurophysiological evidence of their effects on cortical activity is still limited.

Visual Field Defects and Multifocal Visual Evoked Potentials [PDF]
To determine the relationship between spatially localized multifocal visual evoked potentials (mfVEPs) and Humphrey visual fields (HVFs) in patients with unilateral field defects.Humphrey visual fields and mfVEPs were obtained from 20 patients with unilateral field losses due to either ischemic optic neuropathy or glaucoma.

Background: To compare the usefulness of the traditional pattern-reversal Visual Evoked Potentials (VEP) with multifocal VEP (mfVEP) and Frequency-Doubling Technology (FDT) perimetry in the evaluation of the ocular abnormalities induced by acute or ...

Multifocal Visual Evoked Potential mfVEP [PDF]
The waveform of the localized mfVEP response changes in polarity across the horizontal meridian, which could be explained by the position of the generating cortical dipoles relative to the location of the recording electrodes [6]. With bipolar recording, the responses for stimulation of the upper and lower visual fields were reversed in polarity as ...

The multifocal visual evoked potential: An objective measure of visual fields?
We examined the effects of inter-modal attention and mental arithmetic on Humphrey visual field sensitivity and multifocal visual evoked potential (mfVEP) amplitude. Four normally sighted subjects (ages ranging from 24 to 58 years) participated in this study.
