Photon density measured over a cut surface: implications for optical mapping of the heart.

Bradley J Roth1.   

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?
