Julia Nan PID: 720195521 Psychology 101-001 Biological Bases Paper I pledge that I have neither received nor given unauthorized assistance on this assignment A neuron stores resting potential energy when it is inactive. The resting potential of a neuron is the negative charges generated when the positively charged sodium and potassium ions and negatively charged chloride ions flow back and forth across the cell membrane at different rates. When the neuron is stimulated, the channels in the cell membranes open and briefly let positively ions inside the cell, creating a shift in the overall charge of the cell. This shift in charges, or the action potential, then travels directly down the axon. The firing of action potential has certain rules pertained with it. The difference between the positive and negative charges inside and outside of the membrane has to surpass the threshold in order for the action potential

    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.
