Gender differences in pattern reversal evoked potentials in normal elderly.
Pattern reversal evoked potentials (PREPS) were recorded in 51 normal elderly subjects (27 males, 24 females). Elderly females had shorter PlOO and NlSO latencies, greater P100-N150 amplitudes, and higher noise power than elderly males. The N1SO latency differences were significant even when PlOO latency effects were partialled out statistically. Gender differences in P100-Nl50 amplitude were i...
متن کاملPattern reversal visually evoked potentials in infants.
Visually evoked potentials (VEP) were recorded from infants two to six months of age using a checkerboard pattern reversal stimulus. By six months, infants produced the largest amplitude VEP to checks subtending visual angles of 7.5 or 15 minutes of arc, as do adults with 20/20 acuity. This finding indicates that by six months an infant's sensory capacity for a visual acuity of 20/20 is establi...
متن کاملValue of hyperventilation in pattern-reversal visual evoked potentials.
The effects of a standard 3 minutes' hyperventilation on the full-field pattern-reversal visual evoked potential (VEP) were studied in 33 normal subjects, 30 definite multiple sclerosis patients and in twenty-five patients with abnormal VEPs due to either tumourous compression of the anterior visual pathways or optic atrophy of other origin. Significantly greater reductions in P100 latency occu...
متن کاملPattern reversal visual evoked potentials in migraine subjects without aura.
Twenty seven patients with migraine without aura were investigated. The age was between 12 and 54 years; 5 were men and 22 women. The diagnosis of migraine was made according to the classification proposed by the International Headache Society. The method of visual evoked potential was performed with pattern reversal (VEP-PR), with monocular stimulation. The stimulation was performed with patte...
متن کاملImpact of eye-dominance on pattern reversal visual evoked potentials
Background and Objectives: Ocular dominance refers to the tendency to prefer visual input from one eye to the other and is found in majority of the individuals. The role of eye dominance as one of the confounding physiologic variables affecting the PRVEP (pattern reversal visual evoked potential) responses needs to be evaluated. Hence, the present study was planned to assess the influence of ey...
