class braintools.metric.coherence_analysis(lfp1, lfp2, dt, nperseg=None)#

Compute coherence between two LFP signals.

Parameters:

  • lfp1 (Array | ndarray | bool | number | bool | int | float | complex | Quantity) – LFP signals with shape (n_time,).

  • lfp2 (Array | ndarray | bool | number | bool | int | float | complex | Quantity) – LFP signals with shape (n_time,).

  • dt (float) – Sampling interval in seconds.

  • nperseg (int) – Length of each segment. Default: n_time // 8.

Return type:

tuple

Returns:

  • freqs (jax.Array) – Array of sample frequencies.

  • coherence (jax.Array) – Magnitude-squared coherence.
