Small intestinal serosa voltage dataset during ex vivo blood reperfusion and analysis script

Small intestinal serosa voltage is a potential measured as the potential in the serosa relative to the mesentery of the small intestine, which provides good visualization of the neural activity and contractions of the small intestine, as well as the health of the electrical activity of the Interstitial Cells of Cajal that control contractions. This content dataset consists of a .csv format of porcine small intestinal serosa voltage measured during ex vivo blood reperfusion, which mimics the damage to the organ during transplantation in the organ transplant process of extraction, preservation, and transplantation. The MATLAB code performs digital filtering, wavelet analysis, autocorrelation function calculation, and peak frequency analysis and outputs a single figure. These contents will be applied to construct a technique to evaluate the function of the small intestine before transplantation. This method has the potential to be utilized not only to regulate the contraction of the small intestine but also to provide insights that could inform the treatment of associated diseases.
