Fig. 7. Cement gland mechanosensory neuron unattached activity is not influenced by
dimming (LED trace moves down), or fictive swimming. (A,B) Examples from two
tadpoles. Spontaneous activity was recorded by an electrode on the trigeminal
ganglion (trig; vertical scale bar, 0.3 mV) and a ventral root electrode
monitored fictive swimming activity (vr; vertical scale bar, 0.1 mV).
