AFFERENT RESPONSE OF A HEAD CANAL NEUROMAST OF THE RUFF (ACERINA-CERNUA) LATERAL LINE

Abstract 1. 1. The fourth neuromast of the supra-orbital canal of the ruff lateral line is innervated by 300–400 fibres. 2. 2. Afferent activity of 46 fibres was investigated as a function of stimulus amplitude and of stimulus frequency. 3. 3. The dynamic range of the fibres exceeded 30 dB. 4. 4. The gain with respect to acceleration appeared to be constant from a few Hz up to 60–80 Hz. 5. 5. At higher frequencies the gain rapidly fell off (80 dB/decade). 6. 6. Short-term (τ ≈ 100 ms) and long-term adaptation effects were observed in response to large stimulus amplitudes. 7. 7. Fibres had comparable dynamic range and sensitivity. 8. 8. Response properties at stimulus onset and offset confirmed that the neural activity encodes water acceleration in the vicinity of the fish.
