 "Environmental stimuli such as spontaneous changes in temperature, light, touch or wounding can induce electrical signals at any site of the symplastic continuum."

+==== EM signal types ====
+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.
+Variation Potential (VP) - also refered to as 'slow wave potentials'. continuous, varying amplitude in relation to stimululus, non-self perpetualting, singal duration in the order of minutes, amplitude in similar range to APs, amplitude and speed of signals can decrease from the site of local stimulus.
