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) – Sampling interval in seconds. Returns: coupling_strength – Theta-gamma coupling modulation index. Return type: float
