Using a weak electric current to alter a specific brain activity pattern, Frohlich lab increased creativity in healthy adults. Now they’re testing the same experimental protocol to alleviate symptoms in people with depression.
A study by Frohlich lab has provided the first direct evidence that a low dose of electric current can enhance a specific brain pattern to boost creativity by an average of 7.4 percent in healthy adults, according to a common, well-validated test of creativity.
This research, published in the journal Cortex, showed that using a 10-Hertz current run through electrodes attached to the scalp enhanced the brain’s natural alpha wave oscillations – prominent rhythmic patterns that can be seen on an electroencephalogram, or EEG.
“This study is a proof-of-concept,” said senior author Flavio Frohlich, PhD, assistant professor of psychiatry, cell biology and physiology, biomedical engineering, and neurology. “We’ve provided the first evidence that specifically enhancing alpha oscillations is a causal trigger of a specific and complex behavior – in this case, creativity. But our goal is to use this approach to help people with neurological and psychiatric illnesses. For instance, there is strong evidence that people with depression have impaired alpha oscillations. If we could enhance these brain activity patterns, then we could potentially help many people.
