Frequency-specific coupling between trial-to-trial fluctuations of neural responses and response-time variability


Adamo, Nicoletta; Baumeister, Sarah; Hohmann, Sarah; Wolf, Isabella; Holz, Nathalie; Boecker, Regina; Laucht, Manfred; Banaschewski, Tobias; Brandeis, Daniel (2015). Frequency-specific coupling between trial-to-trial fluctuations of neural responses and response-time variability. Journal of Neural Transmission, 122(8):1197-1202.

Abstract

We assessed intra-individual variability of response times (RT) and single-trial P3 amplitudes following targets in healthy adults during a Flanker/NO-GO task. RT variability and variability of the neural responses coupled at the faster frequencies examined (0.07-0.17 Hz) at Pz, the target-P3 maxima, despite non-significant associations for overall variability (standard deviation, SD). Frequency-specific patterns of variability in the single-trial P3 may help to understand the neurophysiology of RT variability and its explanatory models of attention allocation deficits beyond intra-individual variability summary indices such as SD.
