Abstract: BackgroundThe investigation of mindfulness meditation practice, classically divided into focused attention meditation (FAM), and open monitoring meditation (OMM) styles, has seen a long tradition of theoretical, affective, neurophysiological and clinical studies. In particular, the high temporal resolution of magnetoencephalography (MEG) or electroencephalography (EEG) has been exploited to fill the gap between the personal experience of meditation practice and its neural correlates. Mounting evidence, in fact… Show more

“…In the same study, FA also demonstrated greater neural complexity (MSE) and reduced criticality (SNZ) when compared with “emptiness” and “presence” meditation techniques. A similar pattern was observed by D’Andrea et al (2024) when investigating the complexity and criticality of dynamic transitions between MEG microstates among a group of Theravada Buddhist monks. Specifically, FA was associated with greater complexity (LZC) and decreased criticality (LRTC) than rest.…”

“…Thus, a total of 63 manuscripts were eligible for inclusion in this review. Among these, 12 manuscripts conducted secondary analyses using datasets whose original manuscripts were also included in the review ( Calvetti et al, 2021 ; Dadhich et al, 2024 ; D’Andrea et al, 2024 ; Lin, White, Viravan, et al, 2024 ; Lu & Rodriguez-Larios, 2022 ; Martínez Vivot et al, 2020 ; Pandey et al, 2022 ; Sihn et al, 2024 ; Takahashi et al, 2005 ; Ventura et al, 2024 ; Walter & Hinterberger, 2022 ; Yordanova et al, 2021 ), while 1 manuscript included two separate studies with independent samples ( Irrmischer et al, 2018 ). Therefore, the 63 manuscripts included in this review represent results from 52 independent studies ( Fig.…”

“…However, the brain operates as a complex, chaotic system characterized by non-linear dynamics ( Breakspear, 2017 ; Chialvo, 2010 ; McKenna et al, 1994 ; Sporns, 2022 ). In this review, seven studies examined non-linear EEG measures during FA ( D’Andrea et al, 2024 ; Irrmischer et al, 2018 ; Kakumanu et al, 2018 ; Lu & Rodriguez-Larios, 2022 ; Martínez Vivot et al, 2020 ; Ventura et al, 2024 ; Walter & Hinterberger, 2022 ), which can be grouped under the frameworks of (i) complexity, which includes multiscale entropy (MSE), sample entropy (SE), permutation entropy (PE), fractal dimension (HFD), and Lempel-Ziv complexity (LZC), and (ii) criticality, which includes the critical scaling exponent (SNZ) and long-range temporal correlations (LRTC).…”

Exaggerated anticipatory anxiety is common in social anxiety disorder (SAD). Neuroimaging studies have revealed altered neural activity in response to social stimuli in SAD, but fewer studies have examined neural activity during anticipation of feared social stimuli in SAD. The current study examined the time course and magnitude of activity in threat processing brain regions during speech anticipation in socially anxious individuals and healthy controls (HC). Method Participants (SAD n = 58; HC n = 16) underwent functional magnetic resonance imaging (fMRI) during which they completed a 90s control anticipation task and 90s speech anticipation task.

“…The first study demonstrated an increase in MVMFE in highly experienced Rajayoga (ST) meditators (Kumar et al, 2021), the second demonstrated an increase in HFD for a ST meditation and an increase in MSE for FA meditation performed by highly experienced meditators (Walter & Hinterberger, 2022), the third demonstrated an increase in PE and HFD for FA, OM and LK meditation conditions for highly experienced meditators, and an increase in HFD and PE for the OM meditation in beginner meditators (Kakumanu et. al, 2018), and the fourth study reported an increase in LZc for both FA and OM meditation performed by highly experienced Theravada meditators (D'Andrea et al, 2024). Additionally, one study demonstrated an increase in HFD in meditation compared to podcast listening for meditation-naive subjects at week 6 of a mindfulness-based stress reduction (MBSR) course, and an increase in HFD in the meditation condition from week 4 to week 6 of the course (Do et.…”
