. The Biological bulletin. Biology; Zoology; Biology; Marine Biology. AND BEHAVIOR 217 sex were lightly anesthetized in tricaine (Sigma) and lightly paralyzed with pancuronium bromide (Sigma) (600 jug/kg). A microwire electrode was inserted into the dorsal rumus of the anterior lateral line ner\e. which innervates the supraorbital and intraorbital lateral line (3). Once spontaneous or evoked activity of I to 3 afferent fibers was obtained, the electrode was attached to a cylindrical telemetry tag (15 mm diameter X 38 mm length) and mounted externally on the dorsal surface of the fish. The recharge- able telemetry tag was inductively coupled to a bimodal recording stage (45 cm diameter). The stage acts passively to receive the inductive telemetry signal and actively to produce the magnetic field necessary to recharge the capacitors on the tag. The fish is free to move throughout the aquarium; however, data acquisition and tag charging are only possible when the fish remains on or near the stage. Fish were placed on the stage in an experimental tank ( m diameter. 20 cm water depth), and allowed to recover from the surgical procedure for at least 3 h before experiments were conducted. Fish movement was monitored with a digital camera (30 frames/s) and correlated with nerve firing offline (ADInstruments, Chart4: Cambridge Electronic Designs. Spike2). Spontaneous neu- ral activity was recorded in each fiber and correlated with venti- lation cycles. Nerve firing was also recorded when the fish moved independently or was provoked into swimming by gently prodding its caudal fin with a rod. All swimming events consisted of short swimming bursts that displaced the fish up to a body length forward. Swimming speeds (range: cm/s) were deter- mined by videotape analysis. The primary afferents of the anterior lateral line in the toadfish increased firing in response to swimming and ventilatory move- ments. During forward swimming, the firing rate of
