Hey guys, I'm an electrical engineer taking a grad course in a biomed signal acquisition course. Its an interesting course, but I feel like a fish out of water in that I'm not used to it. 1. The problem statement, all variables and given/known data 2. Relevant equations The question is as attached. 3. The attempt at a solution For the first one, I believe this is the positive side, because it depolarizes the cell. In the second questions, my natural instinct is to treat this as an EE problem, in that the AP propogates from the positive to negative direction? Sort of like a battery connected to a circuit. Or, like a battery connected to the cable model of the membrane. The last question I am clueless. I thought the AP propogates down the axon in a lossless manner? At "great distances", would the AP lose some of its strength?
