Visualizing dynamic processes over large, three-dimensional fields of view at high speed is essential for many applications in the life sciences. Light-field microscopy (LFM) has emerged as a tool fast volumetric image acquisition, but its effective throughput and widespread use biology been hampered by computationally demanding artifact-prone reconstruction process. Here, we present framework ...
In mammals, the pupillary light reflex is mediated by intrinsically photosensitive melanopsin-containing retinal ganglion cells that also receive input from rod-cone photoreceptors. To assess the relative contribution of melanopsin and rod-cone photoreceptors to the pupillary light reflex in humans, we compared pupillary light responses in normally sighted individuals (n = 24) with a blind indi...
PURPOSE To investigate the cellular origin of nitric oxide released from the rabbit retina in response to physiological stimulation with light. METHODS The release of nitric oxide from the retina was measured in rabbits anesthetized with urethane. An eye-cup was prepared and was filled with Krebs-Ringer bicarbonate. After washing for 45 minutes, 0.5 ml medium was placed in the eyecup. The med...
