| Action Potential (AP) - rapidly propogating fixed amplitude signals, triggered with stimulus at threshold, do not vary with singal intensity, passivly propogating. signal duration/propogation in the order of seconds, with refractory periods in the order of 10s of seconds or minutes in some plants. amplitudes in the order of 100mV in mimosa. | Action Potential (AP) - rapidly propogating fixed amplitude signals, triggered with stimulus at threshold, do not vary with singal intensity, passivly propogating. signal duration/propogation in the order of seconds, with refractory periods in the order of 10s of seconds or minutes in some plants. amplitudes in the order of 100mV in mimosa. |
