Fast decay of fish synaptic currents

  • Published:
Experientia Aims and scope Submit manuscript

Summary

Teleost miniature end plate currents decay more rapidly than those of birds or tetrapods, with an exponential time constant of about 1 msec at 15°C, but are otherwise normal. The rapid decay is correlated with increased unsaturation and greater fluidity of fish lipids.

Additional information

The work reported here was undertaken at the University of New South Wales, Sydney, Australia, while on sabbatical leave from the University of Auckland. I wish to thank the Auckland University Council for a travel grant, and Professor P.W. Gage of the School of Physiology and Pharmacology, UNSW, for making facilities available in his laboratory. I am especially grateful to Dr R. Balnave for his generous assistance and advice, and to Dr K. Takeda for the voltage clamp measurements.
