The transcranial direct current stimulation refers to a process that involves the simulation of a brain area using some constant but low current. This form of neuron-stimulation involves the delivery of this current to the brain area using some electrodes that are carefully placed on a scalp. The procedure was initially developed to help treat patients diagnosed with brain injuries like strokes. As studies and research about the same have advanced, tDCS has been known to help increase cognitive person with relation to a variety of tasks.
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 current flow used can act in two ways. It can flow through to increase the excitement of the neurons in the areas being targeted. It can also be used to reduce this excitement. These changes cause alteration in the brain functions which then influence some of its activities.
The stimulation process is a relatively simple procedure that only requires a simple set up. It requires you to have two electrodes and a battery powered device which is going to be used to deliver constant current. The device has a cathode and an anode. The anode is the positively charged electrode while the cathode is the negatively charged one. The current is conventionally known as to flow from the anode to the cathode through the conducting tissue which in this case are the neurons.
The skin where the electrodes will be placed is then prepared well to create a strong connection between the electrodes and the scalp when they will be placed on it. The electrodes should be well fixated to the point of interest for effective results. The smaller the size of the sponge electrode, the more focused it will be to effectively deliver the current on the desired point.
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.
