Extended Data Fig. 1. Mapping whisker S1 and S2 regions using widefield calcium imaging and whisker stimulation.

Extended Data Fig. 1

(a) Single whiskers were deflected one at a time by threading them on to a capillary tube attached to a piezoelectric actuator. This figure was adapted with permission from Ethan Tyler and Lex Kravitz (10.5281/zenodo.3925901). (b) Each whisker was deflected multiple times and the results were averaged. The stimulus-triggered average responses from all whisker deflections is plotted on an image of the cerebral vasculature. (c) Individual stimulus-triggered average images from each whisker shows the topographical organisation of the barrel cortex in whisker S1 and the mirrored topography in whisker S2. Panels b) and c) show data from a representative single recording session.
