Our previouswork has demonstrated that the extendedKalman filter (EKF) is a suitable method to track tremor frequencies embedded in spike trains, whose firing rate can be modeled as a sinusoid contaminated with noise. However, when tremor is intermittent, the EKF frequency tracker takes a long time to regain its track of tremor frequencies or never locks on to tremor frequencies even when tremor reappears in spike trains. This is mainly due to the linearization error of nonlinear state space… CONTINUE READING
