Functional role of frontal alpha oscillations in creativity

Abstract

Creativity, the ability to produce innovative ideas, is a key higher-order cognitive function that is poorly understood.

At the level of macroscopic cortical network dynamics, recent electroencephalography (EEG) data suggests that cortical oscillations in the alpha frequency band (8-12 Hz) are correlated with creative thinking.

However, whether alpha oscillations play a functional role in creativity has remained unknown.

Here we show that creativity is increased by enhancing alpha power using 10 Hz transcranial alternating current stimulation (10 Hz-tACS) of the frontal cortex.
