The stimulation referred to as the transcranial direct current stimulation is a procedure carried out to create excitement on some brain neurons by the use of some direct current. This procedure requires the delivery of some direct but constant current flow to the specified target area of the brain using some electrodes. It was initially carried out to help brain injured patients like those who were stroke stricken. The practice has been in use for several years now and researches have been on going to determine to what more extent tDCS can help in offering therapy.
The practice has also been used to enhance the attention span, mathematical abilities, memory loss, coordination, language and even problem solving. This depends with the location where the stimulation is intended to effect. The practice has been highly adapted in recent years as more people continue to learn of its merits. There are many studies that have been conducted to prove its safety and they have shown that it is safe for human use. This is however subject to proper maintenance of safety protocols.
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.
The recent studies have shown ways on how to greatly make this process more effective. This is by the use of multiple electrodes instead of two. Some multiple gel electrodes are placed at several points on the scalp to effectively deliver more current to multiple areas. The effects are therefore higher and more long lasting in this case.
