Spectral and Time-frequency Analysis¶

Source Space¶

Currently, MNE-Python provides a set of functions allowing to compute spectral analyses in the source space. Many these functions return mne.SourceEstimate() objects or collections thereof.

Note

The mne.SourceEstimate() object was initially designed for classical time-domain analyses. In this context, the time axis can actually refer to frequencies. This might be improved in the future.

The following functions are based on minimum norm estimates (MNE).

Alternatively, the source power spectral density can also be estimated using the DICS beamformer, see mne.beamformer.dics_source_power().
