Temporal Stability of Multichannel, Multimodal ERP Recordings

Abstract

Personnel assessment applications of event related brain potentials (ERP) require temporal stability. Visual, auditory and bimodal ERP records were obtained about two hours apart for a group of young adult males. Similar records were obtained from a group of older adults about two months apart. No ERP amplitude or temporal stability differences were found between the two groups. Age was positively correlated with visual stability measures and negatively correlated with auditory stability measures. No correlation of age with bimodal stability measures was found. Large individual subject differences were found for the ERP analog waveform and temporal stability. The ERPs were highly stable within subjects from session to session, whether recorded hours or months apart. Greatest stability was obtained for bimodal presentation, less for visual and least for the auditory records. Differences in patterns of waveform stability were found for site and modality conditions across individuals.

Neuropsychological measures and event-related potentials in alcoholics: Interrelationships, long-term reliabilities, and prediction of resumption of drinking

“…There are only a few studies that have investigated the test-retest reliability of ERPs and NTP. The longest test-retest (ERP) interval to date that we have been able to find in the literature is 2 months (Lewis, 1984). We have been able to investigate the reliabilities of the ERP and NTP variables cited in the first section over a test-retest period of 14 months.…”

Retest Reliability of Individual P3 Topography Assessed by High Density Electroencephalography

“…Since the present study is focused on stability among sessions separated by intervals typically employed in longitudinal studies (pharmacological treatments, neuropsychological rehabilitation programs, etc. ), no review of studies focused on intrasession stability will be included (detailed information can be found in [1], [2], [3]). …”

“…The results of studies to check stability between two sessions separated by periods of days, months or even years have commonly suggested that the P3 parameters (latency and amplitude) show a moderate to high level of reliability (ranging from 0.40 to 0.99) (see [1], [4], [5], [6]). However, most of these studies analyzed a small number of electrodes and could not examine the reliability of the P3 topography in follow-up studies with high density EEG.…”

Effects of low-dose milnacipran on event-related potentials and neuropsychological tests in persons with traumatic brain injury: A preliminary study

“…On the other hand, these parameters of the ERP are less variable within individuals. Lewis [13] reported that ERPs were highly stable within healthy subjects from session to session, whether recorded hours or months apart. Shinha et al [14] also reported stability in ERP measures over a 14-month period in both normal persons and in persons with chronic alcoholism.…”
