Abstract: Five days of integrative body–mind training (IBMT) improves attention and self-regulation in comparison with the same amount of relaxation training. This paper explores the underlying mechanisms of this finding. We measured the physiological and brain changes at rest before, during, and after 5 days of IBMT and relaxation training. During and after training, the IBMT group showed significantly better physiological reactions in heart rate, respiratory amplitude and rate, and skin conductance response (SCR) than the relaxation control. Differences in heart rate variability (HRV) and EEG power suggested greater involvement of the autonomic nervous system (ANS) in the IBMT group during and after training. Imaging data demonstrated stronger subgenual and adjacent ventral anterior cingulate cortex (ACC) activity in the IBMT group. Frontal midline ACC theta was correlated with high-frequency HRV, suggesting control by the ACC over parasympathetic activity. These results indicate that after 5 days of training, the IBMT group shows better regulation of the ANS by a ventral midfrontal brain system than does the relaxation group. This changed state probably reflects training in the coordination of body and mind given in the IBMT but not in the control group. These results could be useful in the design of further specific interventions.

Meta-analysis Provides Weak Evidence for an Effect of Mindfulness on Neural Activity Related to Error-Processing in Healthy Individuals Only
Melissa C. Osborn,Suhasini Shankar,O. Szymanski,Kate Gunningham,Bridget Caldwell,M. Prabhavi N. Perera,Jessica A. Michael,Michael Yufeng Wang,Paul B. Fitzgerald,Neil W. Bailey +9 more
TL;DR: In this article , a meta-analysis was conducted to determine the effects of mindfulness on ERN and Pe amplitudes, showing a weak association between mindfulness and more negative ERN amplitudes at electrode FCz, with inconsequential Bayesian evidence.
Trajectories of Resting Heart Period and Shyness in Adolescent Females Exposed to Child Maltreatment.
TL;DR: Heterogeneity in the developmental patterns of resting autonomic activity in adolescent females exposed to child maltreatment is illustrated; such differences may influence the continuity of some traits linked with socioemotional vulnerability such as shyness.

Mining the Mind: Linear Discriminant Analysis of MEG Source Reconstruction Time Series Supports Dynamic Changes in Deep Brain Regions During Meditation Sessions.
Daniela Calvetti,Brian Johnson,Annalisa Pascarella,Francesca Pitolli,Erkki Somersalo,Barbara Vantaggi +5 more
TL;DR: In this paper, the authors use linear discriminant analysis to demonstrate that the samples corresponding to different meditative or resting states contain enough fingerprints of the brain state to allow a separation between different states, and identify the brain regions that appear to contribute to the separation.

TL;DR: It is hypothesized that changes in EEG parameters may be accompanied by a vagotonic shift of the sympatho-vagus balance, favorable for calming the "cytokine storm" in patients with COVID-19.

Control of goal-directed and stimulus-driven attention in the brain
TL;DR: Evidence for partially segregated networks of brain areas that carry out different attentional functions is reviewed, finding that one system is involved in preparing and applying goal-directed selection for stimuli and responses, and the other is specialized for the detection of behaviourally relevant stimuli.

TL;DR: A baseline state of the normal adult human brain in terms of the brain oxygen extraction fraction or OEF is identified, suggesting the existence of an organized, baseline default mode of brain function that is suspended during specific goal-directed behaviors.
The human brain is intrinsically organized into dynamic, anticorrelated functional networks

TL;DR: It is suggested that both task-driven neuronal responses and behavior are reflections of this dynamic, ongoing, functional organization of the brain, featuring the presence of anticorrelated networks in the absence of overt task performance.

TL;DR: Recent studies examining spontaneous fluctuations in the blood oxygen level dependent (BOLD) signal of functional magnetic resonance imaging as a potentially important and revealing manifestation of spontaneous neuronal activity are reviewed.
Cognitive and emotional influences in anterior cingulate cortex
TL;DR: Various findings are reviewed in relation to the idea that ACC is a part of a circuit involved in a form of attention that serves to regulate both cognitive and emotional processing, and how the success of this regulation in controlling responses might be correlated with cingulate size.
