Near-IR high-resolution integral field spectroscopy of the inner kiloparsec of active galaxies reveal that the molecular (traced by the H2 emission) and ionized gas (traced by [Fe II] and H lines) have distinct flux distributions and kinematics, with the former more restricted to the plane of the galaxies and the latter extending to high latitudes above it. In some cases, the H2 kinematics present a inflowing gas component. Such inflows can trigger a circumnuclear star formation and feed the supermassive black hole (SMBH) in the center the galaxies. We propose to use NIFS+Altair to observe the Seyfert galaxy MRK42, which has well defined ring of circumnuclear star forming regions (CNSFRs). The AGN-Starburst connection can by investigated by comparing the mass accretion rate onto the SMBH (responsible for the nuclear emission growth of the SMBH) and inflow rate (if detected) with the star formation rate (responsible for the growth of the bulge). Moreover, the H-recombination emission lines can be used to estimate the ages, masses and star formation rate of CNSFRs.
