The transcranial direct stimulation process is one that has been in existence for quite some time now. It was initially designed to help the patients who had some severe brain injuries such as strokes. It has however been advanced over the years to help with other various effects. If you are wondering what this process is, or what it generally entails, then you are in the right place. The tdcs uses direct current from a powered device to pass some current through the brain of a patient. The current is passed using some electrodes placed on the scalp of the patient.
The treatment has however been advanced and its applications made diverse. It can now be used to treat various different disparities in the brain such as improving attention span, reducing memory loss, increasing problem solving abilities and more. The different effects achieved with this process are attained by placing the electrodes at different points of the head to stimulate different neurons. The therapy is safe to use provided that all guidelines regarding its safety are adhered to.
The chemistry behind this technique is very simple. It only entails passing a current either from either electrode, through the brain neurons and to the other opposite charge electrode. The electrodes should be carefully set at areas where the simulation will be required. Wrong setting of the electrodes will lead to the attainment of different than the expected results.
The current passed through these neurons is meant to increase their excitement or reduce it. By passing the current from an anode which is the positively charged electrode will lead to an excitement of the neurons. This makes them to be more active and hence the patient will be active in some activities. If the current is passed from the cathode which is negatively charged, the neurons excitement is reduced and thus they become less active.
Given that you have the required equipment and tools for the process; it is quite easy to undertake the procedure. You however need some experience or professional guide in order to conduct it effectively. The powered source will provide you with direct current that flows constantly throughout the procedure. You should also have the electrodes with pads for easy placing on the scalp of your patient.
You should then prepare the skin where the electrodes will be placed at the scalp. This should be done to ensure that the electrodes have a strong connection to the skin for maximum effectiveness. The pads used for connecting the electrodes to the skin are different in styles and designs. The smaller and many in numbers that they are, the better they will be able to create a stronger connection.
One electrode should be placed at the point that needs stimulation and the other on the opposite side of it. The device is then turned on and current let to flow through for some timed period. It can be increased gradually if necessary.
In recent times, the therapy has adopted the use of several electrodes for the process other than just the common type that uses two. This ensures optimal simulation. In the end, long lasting and more effective results are achieved.
