Transcranial Direct Current Stimulation (tDCS) “is a neuromodulatory technique that sends low-intensity, direct current to cortical areas, facilitating or inhibiting spontaneous neuronal activity” (Brunoni, et al., 2012). Transcranial Direct Current Stimulation is a new intervention, which has received a substantial amount of attention over the past decade, and the main goal of tDCS is to modulate cortical excitability. This form of non-invasive brain stimulation has been used with patients with aphasia and paired with behavioral treatments, to explore its therapeutic potential.
The parameters of tDCS differ depending on various factors, which include electrode size and positioning, intensity, duration of stimulation, number of sessions, and

An active saline soaked sponge electrode (5 cm x 7cm), 2mA anodal constant current was applied to Broca’s area daily for 20 minutes over a period of ten days (Volpato, et al., 2013). Furthermore, they were provided with ten sham sessions, which was 30 seconds of stimulation, a control condition, as if they were receiving real stimulation. At the end or beginning of each sham or tDCS treatment, the eight participants were instructed to perform a computerized naming task, where their response time and object naming accuracy was assessed (Volpato, et al., 2013). At the end of the treatment, only one participant demonstrated an improvement in object naming accuracy and response time. The authors, reported that the results of the study revealed that an off-line tDCS approach is not effective in the treatment of chronic aphasia (Volpato, et al., …show more content…
The authors examined, “the potential effects of tDCS in improving spontaneous speech and the ability to use connective words to establish cohesion among adjacent utterances in a group of eight participants with chronic nonfluent aphasia” (Marangolo, et al., 2014). The authors utilized three tDCS conditions: anodic tDCS over the Broca's area, anodic tDCS over the Wernicke's area and a sham condition on all eight adults with nonfluent aphasia. Furthermore, the tDCS intervention involved the F5 and CP5 International 10-20 system for EEG electrode placement, surface soaked electrodes (5cm x 7cm), which held a constant 1 mA current for 20 minutes, performed for ten consecutive daily sessions with 14 days of intersession interval, for 3 months (Marangolo, et al.,
Transcranial Magnetic Stimulation (TMS) is an alternative treatment to medication for severely depressed persons that uses magnetic currents to simulate the brain, thus treating depression symptoms (Fawcett). It has been a successful alternative for many patients when they do not respond to medication, and in 2008, the FDA approved TMS for those with major
Transcranial Electric Current Stimulation (tES) is a non-invasive brain stimulation technique done on the outside of the brain using an electric current to cause activity in the brain.
Repetitive Transcranial Magnetic Stimulation also commonly known as rTMS is a neurostimulation technique which uses electromagnetic energy to stimulate portions of the brain. The existence of Transcranial magnetic stimulation, which is based on the science of bioelectricity, is relatively unknown to the wider masses. The health benefits it can offer covers a wide spectrum of people requiring mental wellness. The use of Transcranial Magnetic Stimulation (TMS) has been approved by Health Canada since 2002.
Consciousness is the state of being awake and aware of your surroundings. Individuals with epilepsy have problems with regaining a conscious state of mind after having a seizure. They never know when a seizure is coming or how long it will take to recover from one, so they have to alter their activities until they are aware of their surroundings again. Thalamic stimulation or deep brain stimulation (DBS) is an approach that helps to demonstrate a way to treat neurological disorders such as epilepsy by surgically implanting small electrodes into parts of the brain and stimulating that area with low to high electrical impulses. Thalamic stimulation is important to individuals that have epilepsy because it will help them regain consciousness quicker and return back to their regular routine. The following article attempted to explain this procedure and its importance.
Transcranial Direct Current Stimulation is a form of neurostimulation in which mild electrical currents are delivered to the desired portion of the brain using electrodes that are placed on the scalp. Based on several recent studies, its application is thought to immediately boost memory, focus, energy, and vigilance, as well as assisting in the treatment of a wide range of drug-resistant mental illnesses. So far, the number of complications found associated with tDCS is greatly outnumbered by the number of benefits. There are two types of neural stimulation involved: anodal and cathodal. Anodal stimulation is meant to excite neuronal activity while cathodal stimulation is meant to inhibit or reduce neuronal activity.
Alzheimer’s disease (AD) is the most common neurodegenerative disorder associated with cognitive deficits and disturbances in behavior. AD is irreversible, however there are multiple treatments to slow down the degenerative progression of the disease. By creating a rat model of AD we seek to observe the effects of deep brain stimulation (DBS). The 5- Choice Serial Reaction Time Task (5-CSRTT), was used to measure the performance of DBS on the rat model of AD. As the task increases in difficulty, the stimulation duration decreases within the 5-CSRTT leading to decreased attentional function. Stimulating electrodes were implanted to the medial forebrain bundle at the level of the lateral hypothalamus. The electrodes provide DBS to the rat models
Transcranial magnetic stimulation is now primarily a treatment type for people that suffer from depression. It utilizes magnetic fields to help stimulate vitally important nerve cells in the brain, cells that help improve mood and eliminate symptoms of depression. Typically, transcranial magnetic stimulation is used when other treatments (such as medicine
Deep brain stimulation is the use of electrical impulses to a deep area within a patient’s brain that is used to treat certain severe psychiatric disorders. Small electrodes are implanted into the brain in an invasive surgery, a series of sessions are held to determine the ideal settings for the execution of electrical currents to the brain, and then a pulse device is placed into the patient’s chest that connect and send electrical currents to the electrodes in the brain. These electrical currents alter the activity in an area of the brain, described by Dr. Gupta as Area 25, a “junction box” for mood-controlling brain circuits. By altering the activity in this area of the brain, doctors can alter the mood of a patient while using the patient’s
The review employed four randomized, controlled clinical trials of deep brain stimulation that occurred in Germany, Austria, United Kingdom, and the United States (Okun, 2012). It did not discuss a detailed description of the search strategy that was used to find all the relevant studies in the review. Participants were randomly assisted to one of two groups – undergo bilateral deep brain stimulation or to only receive medical therapy, which stood as the control group (Okun, 2012). In both the treatment and control group, follow up appointments of the subjects occurred at three months, six months, and one year (Okun, 2012). The Okun (2012) article

Another type of brain stimulation is Electroconvulsive therapy (ECT) uses an electric current to treat serious mental disorders. This type of therapy is usually considered only if a patient's illness has not improved after other treatments (such as antidepressant medication or psychotherapy) are tried, or in cases where rapid response is needed (as in the case of suicide risk and catatonia, for example). Transcranial magnetic stimulation (TMS) is a noninvasive procedure that uses magnetic fields to stimulate nerve cells in the brain to improve symptoms of depression. TMS is typically used when other depression treatments haven't been working. It works like this, during a TMS session, an electromagnetic coil is placed against your scalp near your forehead. The electromagnet painlessly delivers a magnetic pulse that stimulates nerve cells in the region of your brain involved in mood control and depression. And it may activate regions of the brain that have decreased activity in people with depression. This is another form of brain stimulation that helps change many people's lives. As I mentioned before it is to help people that go through depression. Brain stimulation is a very useful method, but many don’t know that there is different types. There is agus
Expand your memory! Make better decisions! Conquer depression! Learn faster! Relieve pain! Could all that of that be possible with just a few little shocks to your brain? According to a growing body scientific literature and a dedicated do-it-yourself community, yes. This new technology is called transcranial direct current stimulation (tDCS) and has made a splash over the past few years with the media, the scientific community, and the most daring DIYers because of its unprecedented effects in treating illness and enhancing cognitive function. tDCS is a simple form of brain stimulation where one or two milliamps of direct current electricity is applied to the skull via two or more sponge electrodes. The current passes through the skull and
Deep Brain Stimulation (DBS) is currently being used to treat patients with Parkinson’s disease however, scientists in Canada and Singapore have completed clinical trails for the treatment of Alzheimer’s. DBS sends electrical impulses to specific parts of the brain through the implantation of an artificial device under the skin below the collarbone known as an impulse generator. The electrical signals are able to alter the brains activity in a controlled manner, which can be programmed by a computer (Takagi, 2012). The ventromedial prefrontal cortex of the brain responsible for cognitive function is targeted by the electrical signals which scientists believe patients had substantial improvement to memory performance and retention (Liu, Jain, Vyas, & Lim,

CAS is a rare neurological, sensorimotor speech sound disorder. According to related research, successful therapy for those with CAS is achieved by incorporating four tenets of motor learning into therapy: precursors to learning, conditions of practice, feedback, and influence of rate. Other studies suggest that intense treatment is necessary for success, but intensity is rarely measured, and research specifically addressing practice amounts had not been conducted prior to this study. The study hypothesized that children would achieve greater in-session production accuracy and generalization of speech targets when treated with a higher frequency of productions.
