In the original article, there was a mistake in the legend for Figure 3 as published. The legend failed to acknowledge the contribution of Dr. Andrew D. Nordin in creating this figure. The correct legend appears below.
Figure 3. EEG dual electrode design for noise cancellation. (A) The dual electrode pair consists of an electrode that records normal EEG and an inverted, noise electrode rigidly coupled to the normal electrode. The noise electrode only records motion artifact and background electrical noise without biological signals. (B) Example of EEG data that were recorded on a phantom head (Oliveira et al., 2016a). The gray signal shows data from a normal EEG electrode; the blue signal is the noise recording; the red signal is the scalp recording. The black signal is the isolated neural signal (red minus blue) after noise correction that is used for analysis. The noise subtraction can either occur in the frequency domain for each pair of dual electrodes, or all the electrode signals can be entered into the independent component analysis to filter out the noise content (Nordin et al., 2018, 2019). This figure was created by Dr. Andrew D. Nordin.
The authors apologize for this error and state that this does not change the scientific conclusions of the article in any way. The original article has been updated.
