Action Potentials Explain the chemical and electrical mechanisms involved in each of the three phases of a neural action potential. Predict the effects of modifications to membrane proteins or ion concentrations on the generation of neural action potentials. Analyze how different factors affect the direction and frequency of action potentials as they are conducted along an axon. Tuesday, February 3, 2015

    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.
