The ``n_cycles`` parameter determines the temporal window length based on the frequencies of interest: :math:`T = \frac{\mathtt{n\_cycles}}{\mathtt{freqs}}`. The ``time_bandwidth`` parameter defines the "time-bandwidth product", which is the product of the temporal window length (in seconds) and the frequency bandwidth (in Hz). Thus once ``n_cycles`` has been set, frequency bandwidth is determined by :math:`\frac{\mathrm{time~bandwidth}}{\mathrm{time~window}}`, and thus passing a larger ``time_bandwidth`` value will increase the frequency bandwidth (thereby decreasing the frequency *resolution*). The increased frequency bandwidth is reached by averaging spectral estimates obtained from multiple tapers. Thus, ``time_bandwidth`` also determines the number of tapers used. MNE-Python uses only "good" tapers (tapers with minimal leakage from far-away frequencies); the number of good tapers is ``floor(time_bandwidth - 1)``. This means there is another trade-off at play, between frequency resolution and the variance reduction that multitaper analysis provides. Striving for finer frequency resolution (by setting ``time_bandwidth`` low) means fewer tapers will be used, which undermines what is unique about multitaper methods — namely their ability to improve accuracy / reduce noise in the power estimates by using several (orthogonal) tapers. .. warning:: In `~mne.time_frequency.tfr_array_multitaper` and `~mne.time_frequency.tfr_multitaper`, ``time_bandwidth`` defines the product of the temporal window length with the *full* frequency bandwidth For example, a full bandwidth of 4 Hz at a frequency of interest of 10 Hz will "smear" the frequency estimate between 8 Hz and 12 Hz.

This should be combined with :meth:`stc.project('pca') ` to follow the definition in :footcite:`SekiharaNagarajan2008`. - ``'nai'`` The Neural Activity Index :footcite:`VanVeenEtAl1997` will be computed, which simply scales all values from ``'unit-noise-gain'`` by a fixed value. - ``'unit-noise-gain-invariant'`` Compute a rotation-invariant normalization using the matrix square root. This differs from ``'unit-noise-gain'`` only when ``pick_ori='vector'``, creating a solution that: 1. Is rotation invariant (``'unit-noise-gain'`` is not); 2. Satisfies the first requirement from :footcite:`SekiharaNagarajan2008` that ``w @ w.conj().T == I``, whereas ``'unit-noise-gain'`` has non-zero off-diagonals; but 3. Does not satisfy the second requirement that ``w @ G.T = θI``, which arguably does not make sense for a rotation-invariant solution.
