Sometimes, just ten minutes is enough for the brain to change its mode of operation. Not with medication, but through a combination of poetry, nature sounds, and mindful attention practice.
This is precisely what an international team of researchers led by Hercules Moraes attempted to investigate. Their pilot study, published on July 28, 2026, in Frontiers in Psychology, was one of the first attempts to study how short artistic-contemplative audio programs affect the brain's electrical activity.
A total of twelve healthy adult volunteers participated in the experiment. Each listened to ten-minute "sound capsules" combining poetic texts, soundscapes, and instructions for mindful attention practice. Throughout the session, researchers continuously recorded their electroencephalogram.
One particular metric turned out to be the most interesting. During listening, the power of the high-frequency beta rhythm (20–30 Hz) reliably decreased, and after the recording ended, it returned to its baseline level. Meanwhile, alpha, theta, delta, mu rhythms, and the low-frequency beta range remained virtually unchanged.
The high-frequency beta rhythm is usually associated with active control of ongoing events, constant analysis of the environment, and readiness to react quickly. Therefore, its decrease can be understood as a moment when the brain's internal "dispatcher" becomes less tense.
But does this mean that a person enters a special aesthetic state of consciousness?
It is not yet possible to answer this question.
From the perspective of predictive processing theory, a decrease in beta activity might suggest that the brain stops comparing ongoing events with its expectations so persistently and begins to pay more attention to internal sensations. However, the same effect can occur during ordinary relaxation or reduced concentration on the external world. EEG data alone is insufficient to distinguish between these possibilities.
It is interesting to consider the results through the lens of modern consciousness theories.
According to global workspace theory, conscious perception is accompanied by the widespread dissemination of information across various brain regions. Here, however, researchers observed only a localized decrease in activity within one frequency range.
The recurrent processing theory, proposed by Dutch neurobiologist Victor Lamme, suggests that subjective experience may arise even before information becomes accessible to the entire brain network. In such a case, a person can indeed experience deep aesthetic immersion, even if the EEG records only very modest changes.
One can imagine a radio receiver. While it is continuously searching for stations, there are many interferences and background operations inside. But once it tunes precisely to the desired frequency, the internal "noise" decreases. The experience of the music itself cannot be seen by observing only the operation of the electronic circuits. A similar situation might occur with the brain: a decrease in the beta rhythm is not yet proof of a special "neural beauty marker."
