The vagus nerve is one of the longest cranial nerves. The vagus nerve connects the brain to the body so that the brain can control body functions. The vagus nerve also has an electrical circuit that involves the heart, lungs, abdomen, chest and neck. The vagus nerve regulates heartbeat, and communicates with the brain regarding: digestion, speech, ect.
There are times when the brain has a little get-together or perhaps even a big one. Due to neurons that do not travel to other parts of the brain via large axons, this may lead to a person's inability to speak or have verbal control of thought and that understanding ability. This can lead to moments of seizures or uncontrolled actions that occur when there is an increase or decrease in electrical activity in the brain. The brain of an individual with a mental disability at times becomes imbalanced during the thought process because of too much or too little activity in the nerve cells. Seizures usually cause physical disruptions or non-understandable actions that indicate that individual needs help to control or calm the situation of brain imbalance. Injuries from seizures can include head trauma, or injury or pneumonia due to food and liquid that enters the lungs during a seizure.
What the brain really needs is a way to communicate neuronal information within the brain and to also regulate the brains electrical activity. A therapy called tDCS or transcranial direct current stimulation involves using a low current device and attaching an electrode to the head externally. This therapy is designed to assist the brain in processing neurons of information. With tDCS neurons will be enabled to function at a normal rate or process. In conjunction with the vagus nerve stimulator, in which an electrode is attached to the neck and a device provides, a certain amount of electrical impulses to the brain; if there becomes an overload or infrequent electrical activity that occurs when the brain or body is prevented from action or expression speech, breathing or ability to do something the vagus nerve stimulation therapy can help regulate electrical activity to a level that is considered adequate. Both stimulation therapies in conjunction can assist in communication and thought process and ensure that the brain does not become overloaded due to attempts at verbal, breathing or physical expression or movement. Now the brain will have more play dates than just with the neurons it normally plays with and the brain will also play well with others as in the rest of the body!
