BME 402 Homework 4 Due 11am, 2/21/06 Neural Cables Be able to derive the cable equation like we did in class using Kirchhoff’s current law. Know the definition of the space constant λ and the input resistance R in for an infinite uniform cable and how these depend on diameter, and know what the steady state voltage profile looks like in a uniform cable for various boundary conditions (i.e. if the cable terminates in a fatter or thinner cable or a closed end, or two or more daughter branches). Know the d 3/2 law for matched input conductances at branch points. Understand why the speed of voltage propagation in a cable depends more on R i than R m . Understand why myelin speeds the propagation of AP’s and why action potentials block when myelin is disturbed. Be able to briefly discuss at least one myelin-related disease. Homework questions: 1. A uniform cable 5 μ m in diameter has R m =20K cm 2 and R i = 100 cm with λ = sqrt (a R m / 2 R i ), and R in = sqrt(R m R i /2)/ 2 π a 3/2 . The cable has a branch point at

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
