Active Galactic Nuclei (AGN) feed on gas that reaches the supermassive black hole in the nuclei of massive galaxies. But the AGN accretion rate is low when compared to the large reservoir of gas usually surrounding AGN, ultimately in the outskirsts of the dusty molecular torus. As demonstrated by theoretical models, this gas is prone to the triggering of star formation. In this presentation, I discuss stellar population studies by our AGNIFS (AGN Integral Field Spectroscopy) group that show excess in the star-formation rate and in the contribution of young stars (ages ~<30 Myr) in AGN hosts when compared to matched control samples of non-active galaxies in the near Universe (z<0.02). In this talk, I present the methodology of our work as a prospect for its use with PFS data to extend the study to higher redshift AGN. I discuss examples of preliminary studies of higher z AGN spectra - that include rest-frame UV coverage - that suggest the presence of Starbursts in NLSy1 and Little Red Dots, but more data is necessary to confirm how common is this along the history of the Universe, and PFS may be the ideal instrument to do this.
