Abstract
During optical mapping of the heart, the signal represents a weighted average of the transmembrane potential. Researchers sometimes illuminate the epicardium and record over a cut surface. My goal is to compare their signal to the photon density within an intact tissue. Does cutting the tissue affect the signal?
