| Abstract: | Neutral hydrogen is an important tracer of galactic dynamics. Hence, observations of the detailed structure and kinematics
of HI are vital in order to determine the relationship between AGN and their host galaxy.
We describe high resolution VLA emission line observations of NGC 1068 at about 600 pc linear resolution and 5.2 km s-1 velocity
resolution. We present the HI morphology of this Seyfert galaxy and discuss its peculiar rotation curve and speculate how
its shape might be related to the Seyfert activity. Related to this, we will highlight the pronounced HI ring within which
the tightly wound CO spiral arms are found, and discuss the high, up to 55 km s-1, velocity dispersions which are found there.
