  I discuss new observations of circumnuclear regions in barred galaxies, both
of their kinematics and their near-infrared (NIR) morphology. New kinematic
observations of M100 confirm that (1) the inner bar-like feature detected
before in this galaxy is in fact a continuation of the large-scale stellar bar;
and (2) the spiral arm-like sites of star formation in the circumnuclear zone
are manifestations of density wave spiral structure in the core of this galaxy.
From a NIR study of similar regions in other barred galaxies, I find that in
many of these regions, sites of star formation are visible in the NIR images,
implying that young stars are responsible for a non-negligible part of the NIR
emission.
