Figure 3. Example of a whole-cell recording from the terminal bulb of the pharynx. A depolarizing step (as shown in the stimulus protocol) elicits an inward current whole cell current. This recording was made from a wild type (N2) pharynx in the presence of 50nM 5-HT.

5. Acknowledgements
Irina Vinogradova contributed to the development of the patch clamp protocols. Enriq Claverol and Christopher Franks developed the automated system for simultaneous acquisition of electrical and video signals. We gratefully acknowledge the pioneering work of the Avery lab who led the way in this field. The Holden-Dye group also acknowledge the support of the Biotechnology and Biological Science Research Council, UK for funding the electrophysiological analysis of C. elegans.
