We investigate the properties of two-dimensional distribution and kinematics ionized gas stars in central kiloparsec a matched sample nearby active (Seyfert) inactive galaxies, using SAURON integral field unit on William Herschel Telescope. The distributions show range low-excitation regions, such as star formation rings Seyfert high-excitation regions related to photoionization by galactic nucleus (AGN). stellar all galaxies regular rotation patterns typical disc-like systems, with...
