Fig. 7. Responses of a type I medial octavolateralis nucleus (MON) unit to a 50 Hz
vibrating sphere stimulus in still (left) and running (15.5 cm s-1;
right) water. Raster plots and level-response functions are as in
Fig. 4. Displacement amplitudes
were 3770, 2300 and 59 µm. In still water, this unit responded to the
vibrating sphere with a decrease in discharge rate. Ongoing discharge rate was
comparable in still and running water. Consequently, the response to the
vibrating sphere was not masked.
