How to improve brain function: new research on transcranial stimulation

Researchers from Boston University conducted a study that showed that transcranial stimulation can improve brain function. Using transcranial alternating current stimulation (tACS) technology, scientists stimulated the brain with rhythmic electrical impulses, resulting in improved cognitive function.

The tACS technology involves wearing an elastic cap with electrodes that deliver weak electrical impulses to the scalp, causing rhythmic pulses in neurons. This makes it possible to change brain activity and improve brain function.

Rhythmic impulses are key to brain health. Research shows that when neurons coordinate their work rhythmically, they communicate with each other more effectively. The tACS technology makes it possible to externally induce rhythmic brain activity, which contributes to improved cognitive function.

However, tACS technology is relatively new, and its effectiveness is still not fully understood. Some studies show positive results, while others believe that the currents used in the technology are too weak to have a direct effect on the brain.

Researchers recently conducted an extensive meta-study of more than 100 published studies using tACS technology. The study found that stimulation of the brain with tACS actually improves cognitive function. In particular, tACS technology showed the best results in improving the brain’s executive function, that is, its ability to adapt to new information.
