<p>tDCS is transcranial direct current stimulation. It is a form of electrical stimulation that is used to treat many conditions and pathologies, both in the brain and in the body. The technology uses a positive and a negative electrode (called the anode and the cathode, respectively). Direct current passes a one-way current through the brain or the body. In the brain, a surge in calcium ions and in sodium ions creates a condition of neuroplasticity, which makes the brain more susceptible to neurofeedback and pEMF conditioning. tDCS&nbsp; It increases the potential of the brain to change, learn and grow.</p><p>tDCS 1) increases blood flow at the targeted areas and, thus, leads to vaso-profusion (which helps to heal wounds on the brain and the body and also encourages angiogenesis and neurogenesis), 2) causes large scale network organization, 3) stimulates/excites the positive electrode site (anode) which increases glutamate and decreases GABA, and inhibits the negative electrode site (cathode) creating more GABA at the site of stimulation, and causes calcium and sodium surges in the glial cells, which leads to flexibility in polarity shifting. TDCS does not force the brain to fire. Some of the symptoms and pathologies addressed by tDCS include migraines, age-related cognitive decline, and other disorders where the tissues of the brain agree damaged or compromised (such as cerebro-vascular issues, stroke, and some epileptogenic profiles). tDCS protocols cause the underlying blood vessels to dilate, which allows oxygenation of the affected areas. A recent meta-analysis showed no serios adverse effets on over 1,000 people across 33,200 sessions (Bikson et al., 2016).<br><br></p><p style="text-align: center;"><img src="@@PLUGINFILE@@/transcranial-direct-current.png" alt="" width="350" height="337" role="presentation" class="img-responsive atto_image_button_text-bottom"><br></p><p style="text-align: center;">Figure : The application of transcranial direct current<br></p><p style="text-align: center;"><br></p>
