ΔF/F traces across fibers for three example stimulation trials at a single site (blue trace, top) and all other recording sites with a significant response to stimulation (bootstrap test, p < 1.0 × 10−6), ordered from top to bottom by their total distance from the stimulation site (shaded from dark to light red). Vertical light blue bars indicate laser periods (4 ms pulses at 30 Hz for 1 s).
