Document Summary
; what does it measure: a single ion equilibrium potential were there is no, goldman equation net flow. In cells that are permeable to two ions the membrane potential lies between the two equilibrium potentials: think about experimental manipulations, what would happen if you decreased external k; or increased external k, decrease, the decrease in ext. K+ causes for decrease in membrane potential: when you increase the outside concentration of. If increased, there will be a steep climb when channels open, then broadly fall. The graph would be broader: has more to do with action potential then the membrane potential. Shows the flow od the ion: permeable to na+ in over rising and overshoot. ; why are: time constant: similar to length but applies to time it a way of measuring how quickly a neurons" voltage level decays to 37% above its resting state after receiving an input signal, usually 5-20ms.
