Sample Abstract
     Comparative Study of the Response to Light on the Sensory Motor Integration of Gill Lateral Cell Cilia in Bivalve Molluscs *Danellie Semple, *Johanne Jean-Pierre, Edward J. Catapane and Margaret A. Carroll, Medgar Evers Colledge and Kingsborough Community College.

    Gill lateral cells (GLC) of bivalves Crassostrea virginica and Mytilus edulis are innervated by serotonin/dopamine nerves. Motor aspects of GLC innervation are well studied. but not the sensory. We found light, food, crab extract and histamine initiated a sensory-motor integration response between mantle rim sensory tentacles and GLC cilia. Histamine is a neurotransmitter in photoreceptors. Near the cerebral ganglia, C. virginica and M. edulis have cerebral ocelli (eyespots) that have rarely been studied other than histological/anatomical reports. We hypothesize cerebral ocelli in both bivalves are light sensitive and involved in histamine mediated sensory-motor integration effecting GLC. We used whole animal with intact gill innervation to access actions of light and a histamine H2 receptor antagonist on cerebral ocelli. Cilia beating was measured by stroboscopic microscopy. An eleven lumen. 1/4 inch diameter spotlight was used to stimulate cerebral ocelli. Stimulating cerebral ocelli with light decreased cilia beating in C. virginica, but increased beating in M. edulis. In both animals, excising cerebral ocelli prevented the response to light. Famotidine, a histamine H2 receptor antagonist, blocked the response to light. We also tested light on mantle rim sensory tentacles in M. edulis and found light caused cilio-excitation, opposite to the cilio-inhibitory in C. virginica. Since C. virginica is nocturnal, while M. edulis is not, opposite responses are not surprising. The study demonstrates sensory-motor integration between mantle rim sensory tentacles and the motor response of GLC cilia, and adds new knowledge of the physiological role of cerebral ocelli in a class of animals where it has not been well studied. It supports the hypothesis histamine is the sensory neurotransmitter for photoreceptors in cerebral ocelli and mantle rim in these bivalves. This work was supported by 690340047 of PSC-CUNY. 2R25GM06003 of the Bridge Program of NIGMS and the Carnegie Foundation.
