Knowledge of neural receptive fields helps decode animal's movement from neural activity in motor brain machine interfaces (BMI). The traditional tuning depth is a coarse metric to evaluate the neuron's tuning properties. The major difficulty of the tuning depth is that it does not allow for a direct comparison among neurons that have very different firing rates. An information theoretic tuning depth based on mutual information is proposed to evaluate how neural spikes encode the kinematic… CONTINUE READING
