A screenshot from VScope (reproduced from its user guide). Top left: A frame from a VSD recording with overlaid ROIs. Top right: Neuronal signals. Top to bottom: optical trace from the selected ROI (blue trace; outlined in red on the left); an intracellular trace (black trace), and other selected optical traces extracted from the VSD recording. (The red trace is a copy of the blue trace, to allow scale comparison.) Bottom: Touch screen–optimized user interface for recording and analysis.
