in neuronal chemistry At rest a typical neuron has a resting potential potential across the membraneof 6060minus 60 to 7070minus 70 millivolts This means thatthe interior of the cell is negatively charged relative to theoutside so sudden change of this membrane potential we will getlike that a large enough depolarization event perhaps resulting frommultiple depolarizing inputs that happen at the same time can leadto the production of an action potential Anaction potential unlike a graded potential is an allornoneevent it may or may not occur but when it does occur it willalways be of the same size is not proportional to the size of thestimulus An action potential begins when a depolarization increases themembrane voltage so that it crosses a threshold value usuallyaround5555minus 55 textmVmVm V At this threshold voltagegated text NaNaN a startsuperscript plus end superscript channels in the membrane ....
