Spatial maps (axial, top; sagittal, middle) of significant changes in DA release (ΔF/F) for three example stimulation sites (stimulation site 3 is the same as E). Each circle is a single recording site, with the stimulation site in blue, sites with a significant evoked response (bootstrap test, p < 1.0 × 10−6) in red, and sites lacking a significant response in gray. Bottom: mean ΔF/F triggered on stimulation offset at all of the sites with a significant response (left, n = 7 trials; middle, n = 9 trials; right, n = 9 trials). Color is ordered by distance from the stimulated fiber (darker colors indicate closer to the fiber).
