Integrated central and autonomic signatures of concentrative and analytical meditation in expert practitioners

Scientific Reports August 29, 2026 Alejandro Luis Callara, Mohammad Hadi Azarabad, Laura Sebastiani et al.

Meditation has long been associated with improvements in mental well-being, emotional regulation, and attentional control. However, the diversity of meditative techniques and variability in participant expertise across studies have hindered the systematic identification of their neurophysiological correlates. To address this challenge, we investigated the neurophysiological signatures of...

Classification of meditative phases through EEG analysis

Research Square July 7, 2026 Maurizio Palmieri, Alejandro Luis Callara, Enzo Pasquale Scilingo et al. preprint

Abstract Meditation has been associated with a range of psychological benefits. However, providing objective and subject-independent markers of distinct meditative phases remains challenging, especially when different meditation practices induce subtly different brain dynamics. This study investigates whether three meditative phases, namely Concentrative, Loving-Kindness, and Emptiness, can be...

Dynamic causal modeling of low-density resting-state EEG in long-term meditation practitioners

Scientific Reports February 26, 2026 Gianluca Rho, Francesco Bossi, Ngawang Norbu et al.

Meditation is a complex cognitive practice associated with significant neurophysiological changes, particularly in long-term practitioners. These individuals represent an ideal human model for investigating neural changes associated to their consistent, frequent, and sustained cognitive engagement. However, in Western societies, long-term practitioners are relatively rare compared to Eastern...

Analytical meditation improves physiological well-being in expert practitioners: a study on central and peripheral neurophysiological correlates

bioRxiv Preprint Server December 8, 2025 Alejandro Luis Callara, Mohammad Hadi Azarabad, Laura Sebastiani et al. preprint

Meditation has been long associated with improvements in mental well-being, emotional regulation, and attentional control. Yet, the diversity of meditative techniques and participant expertise has hindered the systematic identification of their neurophysiological correlates supporting these benefits. To address this challenge, we investigated the neurophysiological signatures of concentrative...

Neuronal correlates of eyeblinks are an expression of primary consciousness phenomena

Scientific Reports August 3, 2023 Alejandro Luis Callara, Alberto Greco, Enzo Pasquale Scilingo et al.

Abstract: The blinking rate far exceeds that required for moistening the cornea and changes depending on whether a person is resting or engaged in cognitive tasks. During ecological cognitive tasks (such as speaking, reading, and watching videos), blinks occur at breakpoints of attention suggesting a role in information segmentation, but the close relationship between cognition dynamics and...

Is Hypnotic Induction Necessary to Experience Hypnosis and Responsible for Changes in Brain Activity?

Brain Sciences May 29, 2023 Alejandro Luis Callara, Žan Zelič, Lorenzo Fontanelli et al. 7 citations

The relevance of formal hypnotic induction to the experience of trance and its neural correlates is not clear, in that hypnotizability, beliefs and expectation of hypnosis may play a major role. The aim of the study was assessing the EEG brain activity of participants with high (highs) or low hypnotizability scores (lows), aware of their hypnotizability level and informed that the session will...
