Abstract: 
We present broadband BVI and Hα photometry and spectroscopy along the major and minor axis of the active, isolated galaxy NGC 6951. All the results point to the conclusion that, apart from its nuclear activity, it is a normal barred Sbc galaxy. The only peculiarity is the too low present star formation rate, with a narrow, well delineated ring 5″ from the center surrounded by dust. The morphology and properties of the inner regions could be the result of the inflow of gas caused by bar-induced instabilities, as predicted by models. We argue that the nuclear activity in isolated galaxies could also be triggered by those same mechanisms and therefore related to the presence of a bar.
