web or Java simulator that might work.) For 20 points towards the raw score on P1, the task is to generate a prediction to answer one of the following questions and then use the simulator to acquire data-i.e., read numbers from the simulator for an appropriate set of values and generate a plot (Excel or by hand) to test your hypothesis. Briefly explain what you varied, why you chose the range of values you did, and whether your prediction is supported. Interpret your results in terms of what you know about the action potential mechanism and discuss what does and does not match your expectations. Choose and do only one. (20pts) 1. How does the peak of the action potential change as the maximum Na+ current changes? 2. How does the duration of the action potential change as the maximum K+ current changes? 3. How does the resting potential change with changes in the K+ external concentration? 4. What is the relation between K+ and Na+ currents at threshold? Test for several stimulus strengths. 5. For threshold stimuli, how are stimulus duration and amplitude related? 6. Any other interesting question you can devise and I approve. Matlab This file contains the zipped source files. On a computer with Matlab, unzip, start Matlab, navigate to the directory Code and make it the active directory, type hhsim. The Help directory contains a Guide that explains controls. The author also provides a download for the Matlab executable version for Windows but it looks like the download may take long
