“…In addition, as opposed to FA and OM, the predominant oscillation during TM is the frontal alpha rhythm as opposed to the theta rhythm. Transcendental Meditation practice has been associated with increased alpha power among the posterior cingulate gyrus, precuneus, and the medial and inferior temporal cortex (Travis and Parim, 2017 ; van Lutterveld et al, 2017 ).…”

“…Determining the neural basis of meditation can potentially be used to improve meditation training and better understand neuronal circuitry. More specifically, oscillatory neurofeedback could be used to correlate an objective measure of brain activity with subjective experience, and thus be used as a tool for meditation training (van Lutterveld et al, 2017 ).…”

Objective: Meditation is one type of mental training that has been shown to produce many cognitive benefits. Meditation practice is associated with improvement in concentration and reduction of stress, depression, and anxiety symptoms. Furthermore, different forms of meditation training are now being used as interventions for a variety of psychological and somatic illnesses. These benefits are thought to occur as a result of neurophysiologic changes. The most commonly studied specific meditation practices are focused attention (FA), open-monitoring (OM), as well as transcendental meditation (TM), and loving-kindness (LK) meditation. In this review, we compare the neural oscillatory patterns during these forms of meditation.Method: We performed a systematic review of neural oscillations during FA, OM, TM, and LK meditation practices, comparing meditators to meditation-naïve adults.Results: FA, OM, TM, and LK meditation are associated with global increases in oscillatory activity in meditators compared to meditation-naïve adults, with larger changes occurring as the length of meditation training increases. While FA and OM are related to increases in anterior theta activity, only FA is associated with changes in posterior theta oscillations. Alpha activity increases in posterior brain regions during both FA and OM. In anterior regions, FA shows a bilateral increase in alpha power, while OM shows a decrease only in left-sided power. Gamma activity in these meditation practices is similar in frontal regions, but increases are variable in parietal and occipital regions.Conclusions: The current literature suggests distinct differences in neural oscillatory activity among FA, OM, TM, and LK meditation practices. Further characterizing these oscillatory changes may better elucidate the cognitive and therapeutic effects of specific meditation practices, and potentially lead to the development of novel neuromodulation targets to take advantage of their benefits.

“…There are several potential mechanisms underlying the interventional effects of mindfulness meditation on hallucination and delusion. First, mindfulness meditation produces brain oscillation changes and increases brain network integration, 7 which could contribute to the decreased abnormal brain activities and reduced hallucination/delusion. Second, In the future, it will be important to investigate the meditationevoked brain changes to further elucidate the potential mechanisms of the benefits from intervention.…”

“…Furthermore, several network metrics, including node centrality indices assume different significance on a local or global scale (Telesford et al, 2011;Antonenko et al, 2018). In that respect the authors make the case for the use of Minimum Spanning Tree as an unambiguous solution, ensuring accuracy, robustness, and reproducibility that also avoids methodological confounding thanks to the way it takes both topological properties and functional connectivity information into account (Tewarie et al, 2014;van Diessen et al, 2016;van Lutterveld et al, 2017).…”

We are not individuals, we are much better described as ecosystems due to trillions of bacteria and other microorganisms that inhabit us. We now know that gut microbiota can greatly influence many physiological parameters that in turn may impact several cognitive functions, such as learning, memory, and decision making processes. This mutualistic symbiotic relation known as the gut-brain axis is also constrained by external factors such as dietary habits such as animal protein and lipids intake. Using a novel combination of Machine Learning and Network Theory techniques, we provide evidence from an indigenous population in Guerrero Mexico, that both brain and gut-microbiota connectivity, evaluated by Minimum Spanning Tree as the critical backbone of information flow, diminish under either low protein or lipids intake. We discuss then how this loss of connectivity may translate into a reduction of the individual’s capacity to cope with perturbations as loss of connectivity may be linked with losses in antifragility.
