Neural Basis of Visually Guided Behavior in the Frog

The frog (Rana pipiens) is an excellent preparation to study visually guided behavior. Prey capture and avoidance behavior. These behaviors appear to have separate underlying neural circuits since lesions of the optic chiasm only affect avoidance behavior and not prey catching (Waldeck et al. 1995).
We would like to determine what these systems are by eliminating the prey catching and saving the avoidance behavior.

The lab is also interested in the function and anatomy of the frog M-cell. The M –cell makes sense in the developmental tadpole as a swimmer, but what is its function in the non-swimming adult frog?
