In an experiment you artificially cut in half (-50% reduction) the number of voltage gated sodium channels that are located on the membrane of the axon hillock. 1.) Which of the following is the most likely result of this experimental manipulation? A. Summation of more IPSPS would be required for an action potential to occur B. This change would have no effect on the value required to reach threshold C. Even with a very large number of summating EPSPS it would be impossible for an action potential to occur D. The value to reach threshold would be higher (more positive) making it less likely for an aetion potential to occur E. All of the above statements are FALSE The made-up drug Jeakyhoss degrades myelin resulting in myelin becoming more porous and therefore a poor insulator. 2.)
