nerve response is phase locked to the stiniulus ( Lotu lotu).
well as in superficial neuromasts (Gorner, 1963). Thus, each nerve fiber
couples only to hair cells with the same orientation.
VI. THE CENTRAL NERVOUS SYSTEM AND FEEDBACK
The central nervous system receives information from a large number
of lateral line sense organs with a wide distribution over the body. Most
fishes are equipped with both types of organs: On a background of
spontaneous nerve firing they signal information about environmental
water motion, its velocity and direction, and the presence of vibrating
