You may be wondering how the brain can be stimulated without opening the skull. People with healthy brain functioning can also benefit from brain stimulation by improving their emotion regulation, attention, learning, problem solving, and memory abilities. Why would we want to alter brain activity? Well, people with brain damage or disorders can resolve potentially problematic patterns of brain activity through stimulation therapy. In this article, we discuss how tDCS can be used to help people to think and feel differently.Įlectrical brain stimulation can be a safe and effective way to temporarily alter brain activity without the need for brain surgery. The cortex can be reached using a method called transcranial (into the skull) direct current stimulation ( tDCS for short). Luckily, many of the brain regions that control these functions are located in the cortex, which is the outer edge of the brain, closest to the skull. Brain stimulation has been used to treat mood disorders and stress, and it can even help people to solve problems, memorize information, and pay better attention. Because electrical charges are responsible for brain activity, electrical stimulation can in turn be used to change the brain’s functioning. Did you know that while reading this your brain is sending off chemical and electrical signals to help you to understand the words and their meaning? Your brain is made up of networks of small cells called neurons that communicate electrochemically to enable you to think, feel, and interact with the world around you.
