While brain waves are known for their components with various frequencies, such as alpha and delta waves, their thermodynamic significance has been unknown. In this study, a novel method was developed to decompose entropy production rates by oscillatory modes, which was then applied to monkey brain activity data. The findings revealed that delta waves, which are slow oscillations, dominate in the anesthetized state, whereas, in the resting state, theta and alpha waves, which are faster oscillations, contribute more to entropy production rates.
These results may provide valuable insights into the role of brain wave oscillations in information processing and is expected to offer a new perspective on understanding living systems.
