Stellar feedback has a notable influence on the formation and evolution ofgalaxies. However, direct observational evidence is scarce. We have performedstellar population analysis using MUSE optical spectra of the spiral galaxy NGC628 and find that current maximum star formation in spatially resolved regionsis regulated according to the level of star formation in the recent past. Wepropose a model based on the self-regulator or "bathtub" models, but forspatially resolved regions of the galaxy. We name it the "resolvedself-regulator model" and show that the predictions of this model are inagreement with the presented observations. We observe star formationself-regulation and estimate the mass-loading factor, $\eta=2.5 \pm 0.5$,consistent with values predicted by galaxy formation models. The methoddescribed here will help provide better constraints on those models.
