Voytek, 2017). Therefore, whilst non-sinusoidal oscillations generate spurious PAC, this does not mean that these oscillations are uninteresting, but simply that common PAC algorithms, such as, the ones employed in this article, are ill-suited for these scenarios. Where non-sinusoidal oscillations are present, PAC analysis could proceed by correcting for non-uniform phase distributions (e.g., van Driel et al., 2015) in order to disentangle nested oscillations from neural spiking (Vaz et al., 2017).
