Intense star formation activity, in the absence of interactions, occurs nearly always in barred spiral systems, but many barred galaxies do not show especially enhanced activity. On the other hand bars provide an efficient mechanism of transport of gas from the disk into the active star forming circumnuclear region (Combes and Gerin, 1987). The type of activity in the circumnuclear regions would also depend on the characteristics of the bars (Arsenault, 1989). The dynamics of the gas inside the bars could also be related to outflows of gas into the halo detected in some barred galaxies with intense nuclear activity.
