WebMay 22, 2024 · Intertrial phase coherence (ITPC) was also computed as a measure of the synchronization of neuronal activity locked by a button press for each frequency, time point, electrode, and observer (Tallon-Baudry et al., 1996; Delorme and Makeig, 2004) according to the following: where n is the number of trials, F k (f, t) is the spectral estimate of trial k … WebApr 1, 2024 · Inter-trial phase coherence. Phase coherence, in general, constitutes a measure of temporal synchronicity between a set of oscillations. In EEG-related studies, a phase-lock value to determine synchronization between two neuroelectric signals was introduced by Lachaux et al. ( 1999) and subsequently led to intertrial phase …
