Bioelectricity

The Mechanism of Origin of Extracellular Potentials

Most people know that electrically active cells in nerves, in the heart and in the brain generate electrical currents, and that somehow these result in measurements we all have heard about, such as the electrocardiogram. But how? That is, what is it that happens within the electrically active tissue that leads to the creation of currents and voltages in their surroundings that reflect the excitation sequences timing, and condition of the underlying tissue. This course explores that topic. Rather than being a primer on how to interpret waveforms of any kind in terms of normality or disease, the goal here is to provide insight into how the mechanism of origin actually works, and to do so with simple examples that are readily pictured with simple sketches and one’s imagination, and then moving forward into comparison with experiments and finding outcomes quantitatively.

great follow up in one review

Great follow up course to the previous within the installment regarding bioelectricity.

challenging but rewarding in one review

Having been out school for over 30 years this was a very challenging but rewarding course for myself.

currents created through in one review

The course gives an interesting view on the measurements of the currents created through the of various organs.

gives an interesting in one review

glad i took in one review

I'm glad i took it The educator is really wants to be boring.

learning so much in one review

Why am I learning so much about a dog or who is whose relative in a bioelectricity course?
