Spine

It would appear, and perhaps rightly so with current day knowledge of surface electrophysiology, that electric potentials can be measured anywhere on the body.

Another interesting aspect that we so far have only spent a short time exploring is the electrical activity over the spine.

The current presentations of electrographic images of the E-DIS systems detail in various ways the values of the measured potentials. When we look at a plot of the back like the ones at the beginning, there is little or no detail shown over the spinal region, or at least it is hard to see.

There are other graphical ways of presenting the results by processing the data differently and one of these methods we have been experimenting with is a contour plot, a similar idea to that used to detail terrain on land maps.

Using some commercial contour software on the data obtained from scanning small sections of the spine along the lower back of one subject, the plots below were obtained.

Focal electrical centres are distinguishable around the vertebrae and, at the bottom, show signs of spreading or radiating further than what could be mapped on the time separated occasions on the same subject. We hope to continue to explore the electrical activity of the spine using this technique and also to develop the contour map idea for this purpose and also explore its value on other body regions.
