             abstract = "In modern models and simulations of galactic evolution, the star 
                         formation in massive galaxies is regulated by an ad hoc active 
                         galactic nuclei (AGN) feedback process. However, the physics and 
                         the extension of such effects on the star formation history of 
                         galaxies is matter of vivid debate. In order to shed some light in 
                         the AGN effects over the star formation, we analysed the inner 500 
                         × 500 pc of a sample of 14 Seyfert galaxies using GMOS and MUSE 
                         integral field spectroscopy. We fitted the continuum spectra in 
                         order to derive stellar age, metallicity, velocity, and velocity 
                         dispersion maps in each source. After stacking our sample and 
                         averaging their properties, we found that the contribution of 
                         young SP, as well as that of AGN featureless continuum both peak 
                         at the nucleus. The fraction of intermediate-age SPs is smaller in 
                         the nucleus if compared to outer regions, and the contribution of 
                         old SPs vary very little within our field of view (FoV). We also 
                         found no variation of velocity dispersion or metallicity within 
                         our FoV. Lastly, we detected an increase in the dust reddening 
                         towards the center of the galaxies. These results lead us to 
                         conclude that AGN phenomenon is usually related to a recent star 
                         formation episode in the circumnuclear region.",
