theta_gamma_coupling

class braintools.metric.theta_gamma_coupling(lfp, dt)

Compute theta-gamma coupling strength using standard frequency bands.

Parameters:

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

• dt (float | Quantity) – Sampling interval (seconds if a float; converted if a Quantity).

Returns:

coupling_strength – Scalar theta-gamma (4-8 Hz phase, 30-80 Hz amplitude) modulation index.

Return type:

Array
