 `spectral_connectivity` has already shown its utility to the neuroscience field. The package has already been used in a number of publications and pre-prints in neuroscience [@KuhnertDetectionDirectedConnectivities2019; @VargaNetworkPathConvergence2021; @LauroSubthalamicCorticalNetwork2021;
   , @Delgado-SallentPhencyclidineinducedpsychosiscauses2021]. Interestingly, it has also contributed to a publication in physics [@CliffUnifyingPairwiseInteractions2022], showing its versatility and easy of use. We hope this package will continue to be useful to the neuroscience community, particularly for non-human electrophysiology data.
