A Spatialtemporal White Noise Analysis of Photoreceptor Response to UV and Green Light in the Dragonfly Median Ocellus

Van Kleef, Joshua; James, Andrew; Stange, Gert


Adult dragonflies augment their compound eyes with three simple eyes known as the dorsal ocelli. While the ocellar system is known to mediate stabilizing head reflexes during flight, the ability of the ocellar retina to dynamically resolve the environment is unknown. For the first time, we directly measured the angular sensitivities of the photoreceptors of the dragonfly median (middle) ocellus. We performed a second-order Wiener Kernel analysis of intracellular recordings of light-adapted...[Show more]
