Connectivity Estimation with Wavelet Coherence
Wavelet transforms can be used to compute coherence in the EEG and estimate dynamic interactions. Here is a primer on how to do this. Analogous…
Effect of EEG Reference Choice on Outcomes
In EEG, voltages recorded at each electrode are computed with reference to another electrode. The choice of this electrode reference impacts a number of EEG measures….
Assessing Connectivity with Phase Locking Value
Assessing phase locking in the signal between two electrodes is often used as a method to assess functional connectivity. Here is a look at how…
