Extended Data Fig. 9: Functional ULM imaging by SVD analysis for an increasing number of stimulation pattern repetitions.

SVD analysis performed on the MB flux signal. (A-F) The different panels show the spatial singular vectors corresponding to the stimulation (left: whole brain; right: zoomed area in the activated barrel cortex) for an increasing number of pattern repetition, from N = 1 (A) to N = 20 (F). (G) Time courses of the corresponding temporal singular vector. (A-G) N = 7 experiments.
