Direct current brain stimulation improves motor skills

In summary, a recent study found that non-invasive anodal transcranial direct current stimulation (tDCS) over the primary motor cortex can improve newly learned motor skills and retain these improvements for at least 3 months. The study was conducted on healthy volunteers but aimed to potentially treat patients with skill losses due to brain injury. However, it is not likely to have an impact on elite athletes who are already near their peak performance levels.

A recent study has shown that non-invasive anodal transcranial direct current stimulation (tDCS) over the primary motor cortex can improve certain newly taught motor skills and those skill gains are retained after 3 months adjusted for time related declines in both treated and control (sham) subjects. Although the subjects were healthy volunteers, the aim of the study was regarding treatment of patients with skill loses due to brain injury.

In other words, I don't think this treatment is intended to improve performance for some NBA players with poor free throw percentages.

Indeed. It seems unlikely that this will help with those who are already near the peak of human ability.
 

1. How does direct current brain stimulation improve motor skills?

Direct current brain stimulation (DCBS) involves applying a small electrical current to specific areas of the brain in order to enhance or inhibit neuronal activity. This stimulation can increase the excitability of motor neurons, leading to improvements in motor skills.

2. What types of motor skills can be improved with direct current brain stimulation?

Research has shown that DCBS can improve a variety of motor skills, including fine motor skills (such as finger dexterity), gross motor skills (such as balance and coordination), and even sports-related skills (such as throwing accuracy).

3. Are there any risks associated with direct current brain stimulation?

While DCBS is generally considered to be safe, there are some potential risks involved. These may include headache, tingling or burning sensations, and mild discomfort during the stimulation. There is also a potential risk for seizures in individuals with a history of epilepsy.

4. How long do the effects of direct current brain stimulation last?

The duration of the effects of DCBS can vary depending on the individual and the specific motor skill being targeted. In some cases, the effects may be temporary and wear off after a few hours or days. However, in other cases, the effects may be longer-lasting and may even lead to long-term changes in the brain.

5. Can direct current brain stimulation be used to treat neurological disorders?

While more research is needed, there is evidence that DCBS can be beneficial in the treatment of certain neurological disorders, such as Parkinson's disease, stroke, and chronic pain. However, it is important to note that DCBS should only be used under the guidance of a trained professional and should not be attempted at home.
