Fluorescence from a rat hippocampal neuron expressing Arch, averaged over n = 98 action potentials. Note the delayed rise and fall of the action potential in the small protrusion coming from the process at 7 o'clock relative to the cell body. The time-averaged fluorescence from the cell has been subtracted to highlight the change in fluorescence during an action potential. The background, in gray, shows the time-averaged image.
