The outer segment of a rod or cone photoreceptor is gently drawn into the glass pipette to record light responses from rod or cone photoreceptors. Rods and cones isolated form a tadpole Xenopus retina following mechanical titration. An isolated rod is drawn into the suction pipette.
Cones are smaller in size and have a characteristic oil droplet in their inner segments.
Many of the physicians at University Hospital are also professors at one of the Upstate Medical University's four colleges.
