Fig 2. Sensitivities of the AMsh cell and the ASH neuron to stimulus strength.

Fig 2

Tactile stimuli of varying displacements were applied to the nose tip of the worm. (A) Touch-induced currents in an AMsh cell evoked by 4, 7, and 10 μm displacements. (B) Inward currents in an ASH neuron evoked by 10, 15, and 20 μm displacement. (C) Amplitudes of touch-induced currents in the AMsh cells and the ASH neurons. A displacement of 4μm was able to evoke currents in the AMsh cells, whereas a displacement <10μm failed to evoke currents in the ASH neurons. (D) Rise-times of currents evoked by a 15 μm displacement. (E) Decay-times of touch-induced currents evoked by a 15 μm displacement. The decay time is measured as the time elapsed for the current to fully recover from the peak. (F) Latencies of touch-induced currents in the AMsh cells evoked by 4, 7, 10, and 15 μm displacement and ASH neurons evoked by 15 and 20 μm displacement. Mean ± s.e.m, n≥4 animals; Voltage clamped at-70 mV.
