Using Transcranial Alternating Current Stimulation and EEG to Understand the Neural Mechanisms of Creative Thinking

We used transcranial alternating current stimulation and EEG to explore the causal role of frontal alpha (10Hz) and gamma (40Hz) oscillations in creativity. Alpha stimulation enhanced frontal alpha power and originality scores, gamma showed no effect. Findings highlight neural oscillations’ role in ideation and provide insights into creativity’s neural mechanisms.
