"The South African botanist Lyall Watson once said: "If the brain were so simple that we could understand it, we would be so simple that we couldn't understand it." Countless studies have been conducted to explain its nature, but the human brain remains one of humanity's greatest enigmas. Similar to the human body itself, the brain requires resources, such as water and nutrients, to function properly once derived from these resources plagiarism.

Get an original essay A stroke occurs when plaque blocks a blood vessel, preventing its circulation by sending resources to specific lobes of the brain, or when a blood vessel bursts, releasing blood into the surrounding meninges. The effects of strokes can range from speech impairment - called aphasia - to paralysis, given the hemispheric location in which the stroke occurs. Strokes cause the death of around 140,000 people every year and, Since it is the leading cause of long-term disability, numerous studies have been conducted to combat this medical tragedy. Given the rise of recent technological advances, noninvasive brain stimulation has become a promising, yet highly experimental, treatment for stroke survivors. The development of research methods has given rise to a number of non-invasive brain stimulation methods. Transcranial magnetic stimulation (TMS) is among the most studied methods because it uses an insulated coil, placed on the patient's scalp, to send electromagnetic pulses through the left side of the brain's frontal cortex, similar to how a brain machine does magnetic resonance imaging (MRI) ago. Once "activated", cells release neurotransmitters. Given that it is one of the cheapest forms of non-invasive stimulation, since its equipment can be transported efficiently, transcranial direct current stimulation (tDCS) seems very promising. Transcranial direct current stimulation uses cathodes to send direct electrical currents to participants' brains. There are two forms of tDCS; Anodal stimulation works to catalyze neuronal activity, while cathodal stimulation minimizes this activity. A study by Agnes Flöel, Nina Rösser, Olesya Michka, Stefan Knecht, and Caterina Breitenstein sought to test the capabilities of anodal transcranial direct current stimulation to help healthy individuals learn a new language and to assist in language acquisition in survivors to stroke. To do this, nineteen right-handed individuals underwent trials of anodal, cathodal, and sham electrical pulses used as control treatments for the brain. The results showed that anodal stimulation promotes faster and more effective learning than other forms of stimulation. While not a direct approach to the brain, researchers at the Louis Stokes Cleveland Department of Veterans Affairs Medical Center conducted a study that intriguingly combined the use of both noninvasive brain computer interfaces and electrical stimulation functional. Noninvasive brain computer interface (BCI) machines use brain activity to control devices outside the body. Functional electrical stimulation (FES) gives an electrical shock to the muscle, which activates the nerves, restoring minimal movement in the muscle. FES can potentially help the mind recover lost signals of movement of a given muscle. The case study included a 43-year-old woman who survived a stroke and had extreme difficulty with joint movements.,.”
