Current Developments with Electroceuticals 

While the idea of today's pharmaceutical treatments brings up images of  chemicals and biological molecules that makeup different drugs, recent developments may change the way we think of curing diseases. Many are predicting electroceuticals, devices which use electrical impulses to fight disease, to soon greatly expand our treatment options in medicine. The basic idea is that the devices would be able to read and interpret natural  electrical impulses through your body’s tightly packed nerve cells, compare these impulses to a healthy person’s to identify the problem with the data they collect, then modify the electrical activity in that area to fix the problem.  Kristoffer Famm, a researcher on the subject, explains that “The medicine will speak the body’s language.”  One of the greatest obstacles is expected to be figuring out which concentrations of nerves to “reprogram” using the devices. However, research is still being done in the hopes of one day being able to connect to any nerve, and from there having the ability to read and write over the activity of all other nerve fibers in the body.
