The therapy can be used to target different areas of the brain and the result is the excitement which stimulates different activities. These include enhancing a patient problem solving techniques, attention span, mathematical abilities, language and even coordination. Over the years, the studies carried out have sought to identify the benefits and demerits that identify with the process. The practice is now commonly utilized considering that with the observation of right safety protocols; it is safe for human use.
The procedure involves simply passing some constant and direct flow of current through the neurons in the brains using some electrodes. The therapist places the electrodes on an area of interest with proper precision in order to attain successful results. The current passing through is intended to induce intracerebral activity.
The flow of a current used is manipulated to either increase or reduce the excitability of neurons at the specific area being targeted. This change in the excitability then alters brain function and thus becomes relevant for various therapies.
You require some very few equipment to set up the procedure. You need two electrodes and a battery powered device that will be able to deliver a constant and direct current flow. This device will provide you a positively charged electrode which is known as the anode and a negatively charged electrode which is called the cathode. The anode dissipates the current and its ions flow from it, though the conducting body and towards the cathode.
To start the procedure, you need to set up the equipment correctly. The skin where the electrodes are supposed to be placed is prepared properly in order for the electrodes to have a strong connection to the scalp. The pads come in different sizes. The smaller their size, the more they are able to focus to the current on the specified target to give a more desired result.
One of the electrodes is placed at the point of interest while the reference one can be placed on the shoulder, neck or a side opposite to the point of interest. The current is then let to flow through for the specified time. It should shut off once the time lapses.
In modern studies, it has been noticed that this process can be improved by using more than two electrodes. These small multiple electrodes are able to cover a larger and more specific cortical structures than the use of sponge electrodes. This in turn generates more and longer lasting excitement changes thus making them much more effective.
