LSD flattens the hierarchy of directed information flow in fast whole-brain dynamics.
Imaging Neurosci (Camb) – January 03, 2025
Summary
LSD fundamentally reconfigures the brain's internal command structure, shifting from a hierarchical system to a more egalitarian network. Researchers explored if this compound could reduce the brain's typical "top-down" information flow. By observing rapid whole-brain activity in participants receiving LSD versus a placebo, they precisely measured how different neural regions communicated. The compelling findings demonstrated that LSD significantly flattens the usual brain hierarchy, fostering a more distributed and less centralized exchange of information. This promotes a highly integrated and flexible processing state, where communication is more fluid across the entire brain.

Interbrain synchronization in classroom during high-entropy music listening and meditation: a hyperscanning EEG study.
Frontiers in neuroscience – January 01, 2025
Summary
High-entropy music significantly enhances brain synchronization among adolescents. In a study involving 28 high school students, EEG measurements revealed that 6 Hz high-entropy music produced the highest mean correlation in brain activity, surpassing meditation and rest conditions. Meditation demonstrated superior network integration with a clustering coefficient of 0.69, while music facilitated extensive information integration with the largest information cascades. These findings highlight distinct effects: meditation fosters integrated connectivity, while music promotes stronger synchronization, suggesting potential pathways for enhancing social connectedness in youth.
