Monitoring Changes in the Intracellular Calcium Concentration and Synaptic Efficacy in the Mollusc Aplysia Bjoern Ch. Ludwar1, Colin G. Evans1,2, Elizabeth C. Cropper1 1Fishberg Department of Neuroscience and Friedman Brain Institute, Mt. Sinai School of Medicine, 2Phase Five Communications Inc. We demonstrate how changes in the intracellular free calcium concentration and synaptic efficacy can be simultaneously monitored in a ganglion preparation of Aplysia. We image intracellular calcium using a fluorescent dye, Calcium Orange, and induce and monitor synaptic transmission with sharp (intracellular) electrodes.
