Cranial Electrotherapy Stimulation (CES) is a treatment for brain disorders that has actually been around for quite some time. This is a non-invasive method of altering brain functioning by using small amounts of electricity. The general idea behind this technology is that you attach a clip to each of your earlobes and then allow a 80 to 600 microAmpere current to pass through.
Deep brain stimulation is a method to alter brain functioning. The idea behind this technology is that scientists implant a small electrode deep within the brain. This electrode delivers controlled jolts of electricity to the surrounding brain tissue. Depending on how it is placed, it can either increase or decrease brain activity in specific areas.
