“…Most importantly, the correlations between age and both visual and auditory delays remained significant after adjusting for sensory acuity. These results suggest that sensory acuity does not play a significant role in our findings, which is consistent with previous studies arguing that optical and retinal factors cannot fully account for age-related delays in the visual evoked response1415162228.…”

Age-related delay in visual and auditory evoked responses is mediated by white- and grey-matter differences

et al. 2017

Slowing is a common feature of ageing, yet a direct relationship between neural slowing and brain atrophy is yet to be established in healthy humans. We combine magnetoencephalographic (MEG) measures of neural processing speed with magnetic resonance imaging (MRI) measures of white and grey matter in a large population-derived cohort to investigate the relationship between age-related structural differences and visual evoked field (VEF) and auditory evoked field (AEF) delay across two different tasks. Here we use a novel technique to show that VEFs exhibit a constant delay, whereas AEFs exhibit delay that accumulates over time. White-matter (WM) microstructure in the optic radiation partially mediates visual delay, suggesting increased transmission time, whereas grey matter (GM) in auditory cortex partially mediates auditory delay, suggesting less efficient local processing. Our results demonstrate that age has dissociable effects on neural processing speed, and that these effects relate to different types of brain atrophy.

“…Age-related slowing of the neural response evoked by simple visual stimuli such as checkerboards has been observed using event-related potentials (ERPs) recorded with electroencephalography (EEG)14151617. Similar effects have also been found for auditory stimuli18192021, complex visual stimuli such as faces2223242526 and olfactory stimuli1727.…”

“…The mirror/projector system has no advantages over the LED system, which has the advantage of producing the most reliable component among scalp-recorded VEPs-the PlOO (P2) component (Stockard et al, 1979;Shearer et al, 1983;Skuse et al, 1984). In our study, the effects of gender and ranges of ages of adult patients and controls had no significant effects on the differences found between these groups (Stockard et al, 1979;Shaw and Cant, 1980). The major disadvantage of pattern-reversal stimulation is related to its sensitivity to the changes in visual acuity, because the pattern response represents only a central visual field area, whereas the flash diffusely stimulates the whole retina.…”

Pattern‐Reversal VEP and Cortical SEP Latency Prolongations in Epilepsy

et al. 1985

Twenty ambulatory outpatients with generalized tonic-clonic seizures with primary generalized discharges and photoconvulsive response on electroencephalogram (EEG) and 11 ambulatory outpatients with partial complex seizures with or without secondary generalization were studied with pattern-reversal light-emitting diode (LED) stimulator visual evoked potential (VEPs) and short-latency median nerve cortical somatosensory evoked potentials (SEPs). The patients with primary generalized epilepsy had significantly prolonged latencies of VEP components P2 and N3 and SEP component P22. The patients with partial epilepsy had significantly prolonged latency of VEP component N3. It is concluded that both functional and structural factors may cause a slowing of central impulse conduction.

“…The latency of the component (P100) is known to increase with age (Asselman, Chadwick & Marsden, 1975;Celesia & Daly, 1977;Shaw &Cant, 1980, and. On the contrary, it has been known that although the waveform of the pattern reversal VECP altered in infants (Spekreijse, 1978), no significant change with age over the rest of the life span was found (Celesia & Daly, 1977;Snyder, Dustman & Shearer, 1981;Halliday et al, 1982, and.…”

Pattern reversal visually evoked cortical potentials were recorded from 70 normal volunteers, aged from 4 to 70 years. Eleven reversal frequencies between 1 and 20 rev/sec were presented. The progressive reduction in the amplitude of the P100 component with age for lower frequency ranges was shown up to the age decade of 30-39 years and the temporal tuning curve became a constant pattern after 40 years. However, there was a trend that the maxima of the tuning curve shifted toward lower frequencies with age after 30 years.
