WitrynaIn 1678, while doing dissections of sharks, the Italian physician Stefano Lorenzini discovered organs on their heads now called ampullae of Lorenzini. He published his findings in Osservazioni intorno alle torpedini. The electroreceptive function of these organs was established by R. W. Murray in 1960. Witrynaelectrosensory organs of cartilaginous fi shes (Chondrichthyes). These organs, the Ampullae of Lorenzini (AoL), are widely distributed and comprise a series of gel-fi lled canals emanating from pores in the skin (Figure 1A).
