Voltage Activated

Recreational Vehicle - Terms
... A solenoid which is wired first in the 12v system that, when activated, opens or closes and turns 12v power on or off to that system ... Taking power from the tow vehicle's battery, it is activated by sensing voltage to the brake lights ... applied as well as incorporating manual operation to allow the trailer brakes to be activated independently from the tow vehicle brakes ...

Action Potential - Neurotransmission - Anatomy of A Neuron
... They have a high concentration of ligand activated channels ... the surface of the soma is populated by voltage activated ion channels ... by having an incredibly high concentration of voltage-activated sodium channels ...

Action Potential - Propagation
... molecular level, this absolute refractory period corresponds to the time required for the voltage-activated sodium channels to recover from inactivation, i.e ... There are many types of voltage-activated potassium channels in neurons, some of them inactivate fast (A-type currents) and some of them inactivate slowly or not inactivate at all this variability ... On the other hand, all neuronal voltage-activated sodium channels inactivate within several millisecond during strong depolarization, thus making following depolarization impossible ...
