are valuable electrophysiological investigations to delineate optic neuropathy in a variety of visual disorders.

During offline data processing, VEPs
evoked by different disparities were only extracted when the viewers were under comfortable state, so that the classification contributes to visual discomfort prevention.
However, previous studies regarding visual dysfunction, as assessed by the VEP
, in PD patients versus general populations generated mixed results [8-10], which could be due to small sample sizes of these individual studies (PD case numbers < 50 for all studies).

tasks from a representative subject.
The behavioral performance of adolescents with T1D in a simple oddball test of executive functions was fully comparable with that of the control group; however, the AUC increase of the P3b component suggests a neural mechanism compensating for a subclinical visual impairment manifested by the delayed P100 peak time of pattern-reversal VEPs
Conclusion: Relative to PS membrane-based HDF, the survival rate tended to improve and inflammation was subdued earlier due to the antioxidant activity and early attenuation of inflammation associated with VEPS
No significant differences were seen between the four drugs between pre-treatment and second-year VEP
abnormalities (Figure 7).
The visual evoked potential (VEP
) is the potential recorded from the occipital region in response to visual stimuli with a long latency response.
ARX modeling has been widely adopted by researchers to rapidly extract middle latency AEPs, VEPs
, and SEPs.
were performed by checkerboard pattern reversal displayed on a TV monitor at a viewing distance of 90 cm.
With the advent of sophisticated gadgets like MRI/CT brain scans and computerised Visual Evoked Potentials (VEP
) testing, the diagnostic work-up has become easier, sharper and more focussed.
