Long-term meditation practice is linked to structural changes in the brain. Magnetic resonance imaging of 20 experienced Insight meditation practitioners showed greater cortical thickness in regions involved in attention, interoception, and sensory processing, including the prefrontal cortex and right anterior insula, compared to matched controls. The difference in prefrontal thickness was most pronounced in older participants, suggesting meditation may counteract age-related cortical thinning. Thickness in two regions also correlated with meditation experience. These findings provide the first structural evidence that meditation practice can induce experience-dependent cortical plasticity.

Mindfulness meditation has become widely used in therapy, corporate wellness, education, and the military, but the research backing it has faced criticism for poor methodology and misinformation. This article reviews the current state of mindfulness research, discussing difficulties in defining mindfulness, the proper scope of studies, and key methodological issues. The authors summarize what is known and unknown, offering a prescriptive agenda for contemplative science that focuses on assessment, training, possible adverse effects, and brain imaging. The goal is to inform scientists, media, and the public, minimize harm, curb poor research practices, and stop the spread of misinformation about mindfulness's benefits, costs, and future.

Interoception, the sense of internal bodily signals, is essential for embodiment, motivation, and well-being but remains poorly understood. This review integrates perspectives from neuroscience, clinical practice, and contemplative studies, introducing an expanded taxonomy of interoceptive processes. It argues that many of these processes can be explained by a predictive coding model of mind-body integration, which describes tension between expected and felt body sensations. This model parallels contemplative theories and links interoception to affective and psychosomatic disorders. Maladaptive interpretation of bodily sensations may underlie many contemporary maladies, and contemplative practices may reduce these biases, restoring a sense of presence and agency.

Body awareness is a key element in mind-body therapies such as yoga, Tai Chi, and mindfulness meditation, yet its meaning across these approaches is not always clear. Through focus groups with leading practitioners and their patients, the study finds that body awareness is understood as an inseparable part of embodied self-awareness, realized through action and interaction with the environment. It is seen as an innate tendency of the organism toward self-organization and wholeness. Patients experience a progression toward greater unity between body and self, mirroring a philosophical concept of embodiment as a dialectic experienced at distinct developmental levels.

Standardized mindfulness practices that focus attention on breath and body sensations may work by training the brain to better regulate alpha rhythms (7-14 Hz) in the primary somatosensory cortex. These alpha rhythms filter sensory information entering the neocortex. The framework suggests that in chronic pain, somatic attention in mindfulness reduces pain-focused attentional resources by altering alpha activity. In depression relapse prevention, somatic attention competes with rumination, as internal cognitive processes rely on alpha filtering. A computational model predicts enhanced top-down modulation of alpha through precise timing changes in thalamocortical inputs. The theory aligns with Buddhist teachings that mindfulness begins with mindfulness of the body, proposing that enhanced alpha regulation improves detection and regulation of mind-wandering.

Meditators' subjective experiences during a real-time fMRI neurofeedback study align with activity in the posterior cingulate cortex (PCC), a core region of the default mode network. Reports of undistracted awareness—such as concentration, observing sensory experience, and effortless doing (including not efforting and contentment)—correspond with decreased PCC activity. In contrast, experiences of distracted awareness (distraction, interpreting) and controlling (efforting, discontentment) correspond with increased PCC activity. The findings also generated novel hypotheses, including a distinction between meditating and trying to meditate, offering insights into how meditation relates to mind wandering and self-related thinking.

Equanimity, an even-minded mental state toward all experiences regardless of their pleasantness, is proposed as a key outcome measure for contemplative research. While mindfulness has been used as a measurable outcome of meditation, it encompasses multiple components, some better characterized as equanimity. The article defines and discusses the inter-relationship between mindfulness and equanimity from classical Buddhist and modern psychology perspectives, reviews meditation techniques for cultivating equanimity, and examines psychological, physiological, and neuroimaging methods for assessing it. Equanimity captures potentially the most important psychological element in improving well-being and should be a focus in future research.

In adults with mild cognitive impairment (MCI), an 8-week Mindfulness Based Stress Reduction (MBSR) program increased functional connectivity between the posterior cingulate cortex and both the medial prefrontal cortex and hippocampus, and showed trends of reduced hippocampal atrophy compared to usual care. These preliminary results suggest MBSR may positively affect brain regions linked to MCI and Alzheimer's disease, though larger studies with longer follow-up are needed.

The rubber hand illusion (RHI) is not an all-or-nothing experience but involves nuanced perceptual changes that affect both the rubber hand and the participant's real hand. These changes vary greatly between individuals and evolve over time. The study investigated the phenomenology of the RHI, assessing whether typical control conditions impact the sense of body ownership and whether different stages emerge in the illusion's development.
