The analysis of a sample of 30 isolated spiral galaxies with and without an AGN results in active and control galaxies having similar bulge and disk properties (since both samples are selected to match in morphological and bar classification, they have similar bar percentages). Secondary bars seem also to be indistinguishable. The central kinematics (both stellar and gas) are also studied in order to put some constraints on the processes required to fuel AGNs. Together with previous results, this points to AGNs being an episode of the life of galaxies, providing that the fuel is available and the accumulation mechanisms are at work.
