WebOct 26, 2024 · There’s two different metrics that people use, one that uses only phase information (inter-trial phase coherence, like phase-locking-value) and one that keeps also amplitude information (inter-trial linear coherence, like coherence). But I’ve read different papers referring to either of the two when talking about ITC. WebConnectivity estimates for EEG/MEG time series data. FieldTrip has a consistent set of low-level functions for the computation of connectivity, i.e. estimating a bivariate or multivariate quantity from electrophysiological data, both on the sensor level and on the source level. The objective of supplying these low-level functions as a separate ...
