Can I make an After Effects layer follow cursor movement?

Hi,

Is it possible to specify a particular layer in my After Effects animation to follow the movement of the cursor? I would like just the pupils in my animation to follow the movement of the cursor, with the pupils only moving on a horizontal plane with breakpoints on the left and right to ensure the pupils don’t move outside of the eye area. Ideally I would like to retain the blinking of the eyes also.

The animation is currently made up of two animated elements; the eyelid which is a shape layer with scale keyframes and the pupils which are connected to a null with position keyframes.
