Fig. 7. Simultaneous extracellular recordings from two neurosecretory units (identifiable by action potentials of long
duration) from the urophysis of Tilapia nwssambica. Intravascular injection of NaC1-free hypotonic solution depressed
the activity of unit I, which had been firing spontaneously with moderate frequency, and activated unit 11, which had
been almost silent. From Yagi and Bern (1965).
