Detecting tremors in microelectrode recordings without using a spike detector

Tremor detection in extracellular neuronal recordings has required spike detection because tremors in extracellular neuronal recordings are caused by the fluctuation of action potential's firing rate. This work describes an automatic tremor detection algorithm of extracellular neuronal recordings without using a spike detector. The new algorithm is robust to noise and its performance is not affected by various morphologies of action potentials.
