About this Course

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 course to the previous within the installment regarding bioelectricity. Taught me quite a lot and am looking forward to further releases to the series if they are in the works.

Having been out school for over 30 years this was a very challenging but rewarding course for myself. I'm glad i took it

The poor production of the course is the only downfall. The course itself is well built and has helped me a great deal in beginning to understand bioelectricity. Thanks for the course!

The educator is really wants to be boring. The questions doesn't reflect the material. Why am I learning so much about a dog or who is whose relative in a bioelectricity course?
