1. Lecture homework due 9/9/08 Name _______________________________ 2. What is the formula for the Nernst equation? What does the Nernst Equation allow you to predict? What exactly do you have to measure to make the prediction (make sure you understand this)? 3. What three assumptions must be met before the Nernst Equation allows for an accurate prediction? 4. Which ion(s) provide an accurate prediction of the resting potential and why? Which ions don't and why? 5. What important inferences were early neuroscientists able to draw from measuring sodium, potassium and chloride concentrations on the two sides of an axon membrane and using those concentrations to try to predict the voltage difference across the membrane with the Nernst equation? 6. Draw an action potential as it would look on an oscilloscope and describe what accounts for the rising part of the action potential and the overshoot of zero, the descending part of the action potential and the undershoot of the resting potential,
