Meditation practices with a wider attentional focus, such as Shoonya meditation, are associated with longer intrinsic neural timescales (INTs) in the brain, measured as the autocorrelation window (ACW) of EEG signals, compared to practices with a narrower focus like Mantra or Vipassana meditation. The study compared three groups of highly proficient practitioners from different traditions and a meditation-naïve control group. The results indicate a correspondence between the width of attentional scope and the duration of neural temporal windows, suggesting that subjective attentional width relates to objective neural activity patterns.
A commentary on a study about brain dynamics that predict response to psilocybin for treatment-resistant depression. The original study by Vohryzek and colleagues investigated how brain activity patterns before and during psilocybin treatment might identify which patients with treatment-resistant depression are likely to benefit. The commentary discusses the implications of these findings for understanding how psychedelics work in the brain and for developing personalized treatment approaches.
