Responses of rat lateral hypothalamic neuron activity to dorsal raphe nuclei stimulation.

abstract：:Over the past 3 decades, various algorithms used to decompose the electromyographic (EMG) signal into its constituent motor unit action potentials (MUAPs) have been reported. All are limited to decomposing EMG signals from isometric contraction. In this report, we describe a successful approach to decomposing the surf...
