4. Na+ channels and Action Potential Initiation. Action potentials are often initiated at the axon hillock, where the axon leaves the cell body. The axon hillock has a high density of Na+ channels, which lowers the threshold for initiating an action potential. MetaNeuron can be used to measure the effect of Na+ channel density on the threshold of action potential generation. Vary "gNa max" from 200 to 380 mS/cm2 in 20 mS/cm2 steps. (Na+ channel density is proportional to gNa max.) For each "gNa max" value, determine the threshold stimulus amplitude (in μA) for initiating an action potential. Plot the threshold current as a function of gNa max. Why does the action potential threshold vary as Na+ channel density is changed? 5. Action Potential Membrane Conductances. Starting with the default parameter values. Select "Show ionic conductances" in the "Conductances and Currents" window. The green and blue Iraces show the time course of the Na+ and K+ conductances that are activated during…
A drug specifically blocks the Na+/K+ ATPase pump. What effect might this have on the action potential? O It will shorten the duration of the action potential as there will not be as many ions available to cross the membrane. None, as action potentials rely on channels for Na+ and K+ to cross the membrane, not pumps. It will not have an immediate effect, but eventually action potentials will stop as the Na+ and K+ gradients are depleted. It will make action potentials more likely to occur as the pump normally makes the cell more negative, so without it the membrane will reach threshold more easily.
