Real-Time Recording and Processing of Spike Electrical Activity of the Small Intestine in Experiments on Rats.

Real-time recording technique and mathematical processing of the spike electrical activity in the small intestine were developed for chronic experiments on rats. Open-source software was employed to digitize electromyograms and to process them in a real-time mode with a fourth-order nonlinear differential energy operator. This method improved identification of spike electrical activity in the small intestine in experiments.
