This video is part of the nanoHUB-U course "Introduction to Bioelectricity." (http://nanohub.org/courses/bioelec)

This course introduces students to The fundamentals of bioelectricity of the mammalian nervous system. Passive and active forms of electric signaling in both intra and inter-cellular communication at the atomic, molecular, and engineered device level. Mathematical analysis including the Nernst equation, core conductors, cable theory, and the Hodgkin-Huxley Model of the action potential. Neuromodulation with nano-engineered sensors and actuators.
