Example of activity traces obtained from calcium imaging for interneurons during natural arousal and artificial arousal (LC stimulation) across days.
Example of activity traces for astrocytes during natural arousal and artificial arousal (LC stimulation) across days.
Scheme illustrating the central finding: LC stimulation vs. natural arousal elicit distinct cellular responses across cell types.

Three images with figure excerpts from the paper, highlighting 1) single-spike detection analysis, 2) autocalibration analysis, and 3) non-linearity of calcium-to-fluorescence transfer functions and their effect on the reporting of complex spiking events.
