A team of researchers at the University of North Carolina used 20 Hz currents to test 20 volunteers to stimulate the natural alpha wave oscillations in their brains. After strengthening this "alpha brain wave", people's creativity has been improved by about 8%, and the same method is expected to be used to treat depression. The research results were published in the journal Cortex. Alpha brain waves appear in the low range between 8-12 Hz, which is most prominent when we close our eyes or fall into meditation, which allows scientists to relate them to creativity.
When we are faced with emergencies and urgent tasks, we present high-frequency gamma brain waves.
To prove that Alpha brainwaves stimulate creativity, the research team connected three electrodes to the head of 20 healthy adults, then applied a painless current and applied stimulation for 30 minutes. The subjects then participated in the Torrance Test of Creative Thinking. Test results showed that subjects who received current-stimulated alpha brain waves performed much better than those who did not.
At the same time, the team repeated the method to enhance gamma brainwave stimulation in the subjects, but the results did not improve creativity.
The main author of the paper, Flavio Frohlich, said: "Our research is proof of concept. Strengthening alpha brainwaves can actually improve creativity, but our goal is to treat neurological and psychiatric diseases in this way." There is already conclusive evidence of depression. Alpha brain waves in patients with symptoms are impaired. “For people with depression, it is very meaningful to strengthen alpha brain waves because it is a non-invasive and inexpensive treatment model.â€
The University of North Carolina's research team used low-value currents to enhance the so-called "alpha brainwaves," which increased human creativity by up to about 8%.
The picture shows the natural alpha wave oscillating brain waves of the human brain. Scientists say that strengthening such brain waves will hopefully treat depression. n>8%.
To prove the theory that alpha brainwaves stimulate creativity, the research team connected three electrodes to the heads of 20 healthy adults, then applied a painless current and applied stimulation for 30 minutes. Brain activity was then recorded using an electroencephalogram.
