Document Summary

In bulla, the pacemaker cells are all clustered at the base of the eye. Discovered that these cells were able to maintain rhythmicity. Started cutting out pieces of the eye, first the lens and the retina. Finded that rhythms persisted without all of the retina. Rhythm still somewhat remains, but its reliability goes down. To see if the cells were actually responsible for the compound action potential. Took fibe optics and luminated either the whole eye through the retina, or only the brns. If you illuminate the photoreceptor: asynchronous action potential. If you shine light on the base of the eye: large, synchronous discharges from brns. Cap rhythms and the phase response curve to light. Change in phase shift response from the illuminated eye. The eye can shift, it can be entrained by light cycles. Mechanism: what is it in that cell that"s creating the rhtyhm. Follow the light input pathway deeper and deeper into the cell.
