The Response of the Ampullae of Lorenzini of Elasmobranchs to Mechanical Stimulation

R. W. MURRAY 1

1 Department of Zoology and Comparative Physiology, Birmingham University

1. The ampullae of Lorenzini are sensitive to weak tactile stimulation applied to the ends of their jelly-filled tubes.

2. Either an increase or a decrease in their resting discharge frequency may be caused, each with an opposite after-effect.

3. ‘Adaptation’ is total, being three-quarters completed in 3-8 sec. This ‘adaptation’ probably includes accommodative changes of the tissues.

4. The function of the ampullae is discussed, but no definite conclusion can yet be reached.
