Mindfulness practice leads to increases in regional brain gray matter density. Abstract. Therapeutic interventions that incorporate training in mindfulness meditation have become increasingly popular, but to date, little is known about neural mechanisms associated with these interventions. Mindfulness- Based Stress Reduction (MBSR), one of the most widely used mindfulness training programs, has been reported to produce positive effects on psychological well- being and to ameliorate symptoms of a number of disorders. Here, we report a controlled longitudinal study to investigate pre- post changes in brain gray matter concentration attributable to participation in an MBSR program. Anatomical MRI images from sixteen healthy, meditation- na. Changes in gray matter concentration were investigated using voxel- based morphometry, and compared to a wait- list control group of 1. Analyses in a priori regions of interest confirmed increases in gray matter concentration within the left hippocampus. Whole brain analyses identified increases in the posterior cingulate cortex, the temporo- parietal junction, and the cerebellum in the MBSR group compared to the controls.

Mindfulness meditation has been reported to produce positive effects on psychological well- being that extend beyond the time the individual is formally meditating. Over the last three decades mindfulness meditation practices have been increasingly incorporated into psychotherapeutic programs, to take advantage of these benefits (cf., Baer, 2.

A large body of research has established the efficacy of these mindfulness- based interventions in reducing symptoms of a number of disorders, including anxiety (Roemer et al., 2. Teasdale et al., 2. Bowen et al., 2. 00. Tapper et al., 2. Grossman et al., 2. Carmody and Baer, 2. Mindfulness meditation involves the development of awareness of present- moment experience with a compassionate, non- judgmental stance (Kabat- Zinn, 1. It has been suggested that this process is associated with a perceptual shift (Carmody, 2. Neuroimaging studies have begun to explore the neural mechanisms underlying mindfulness meditation practice with techniques such as EEG (Davidson et al., 2. Slagter et al., 2.

And it occurs to me that while some of you have been following them from the beginning, a lot of people come to them cold in the shape of one story or another.

Recently, several cross- sectional anatomical MRI studies have demonstrated that experienced meditators exhibit a different gray matter morphometry in multiple brain regions when compared to non- meditating individuals (Lazar et al., 2. Pagnoni and Cekic, 2. H. While most of the brain regions identified have been reported in only one of these studies, the divergent results are likely due to differences in participant characteristics, type of meditation, and data analysis methods (see Table 1). Group differences in the hippocampus and the right anterior insula, however, have each been identified in at least two of the studies. Furthermore, activation in both regions has been reported during meditative states (hippocampus (Lazar et al., 2. H. The hippocampus is known to be critically involved in learning and memory processes (Squire, 1. Corcoran et al., 2. Milad et al., 2. 00. Craig, 2. 00. 9) - functions which have been shown to be important in the process and outcomes of mindfulness training (Bishop et al., 2. Shapiro et al., 2. Ortner et al., 2. Overview of morphometric studies on meditation. A growing body of literature has demonstrated that neural systems are modifiable networks and changes in the neural structure can occur in adults as a result of training. For example, longitudinal studies have shown task- specific increases in brain gray matter as an effect of acquisition of abstract information (Draganski et al., 2. Draganski et al., 2. Colcombe et al., 2. Ilg et al., 2. 00. Cross- sectional studies have established that differences in regional gray matter are associated with performance abilities (Mechelli et al., 2. Milad et al., 2. 00. Studies of experienced meditators have also suggested the possibility of structural plasticity, but their cross- sectional designs did not exclude the possibility of pre- existing group differences, precluding causal conclusions. Here we report a longitudinal study of gray matter changes associated with a mindfulness- based intervention. The focus of the study was to identify brain regions that changed in association with participation in an eight- week Mindfulness- Based Stress Reduction course (MBSR; Kabat- Zinn, 1. This group program aims to improve participants’ mindfulness and well- being, and reduce their levels of perceived stress. The study was an attempt to find objectively measurable neurological changes that could underlie the trait- changes associated with mindfulness practice. Changes in gray matter concentration were investigated using voxel- based morphometry. Focused analyses were conducted for the hippocampus and insula as our predefined regions of interest. Exploratory analyses were then performed on the entire brain and compared to a control group. Methods. 2. 1 Participants. MBSR participants were recruited among individuals enrolled in four MBSR courses held at the Center for Mindfulness at the University of Massachusetts Medical School. The courses included physician- and self- referred individuals from across New England who were seeking stress reduction. Individuals were included in the study if they self- reported as physically and psychologically healthy and not taking any medications. Further inclusion criteria were: no meditation classes in the past six months, no more than four classes in the past five years, or ten classes in their lifetime; 2. MRI scanning (i. e., metallic implants, claustrophobia); commitment to attend all eight classes and perform the prescribed daily homework. Eighteen healthy, right- handed individuals were enrolled in the study, 8 male and 1. SD: 4. 0. 4 years). Due to discomforts during the first MRI scanning session, two participants did not return for the second session. The resulting sample consisted of 6 male and 1. SD: 4. 1 years). Ethnicities were: 1. Caucasians, one Asian, one African American, and one multi- ethnic. Participants had an average of 1. SD: 1. 9 years). Reimbursement for study participation was a discounted MBSR course fee. The control sample consisted of 1. SD: 9. 2 years) and an average of 1. SD: 1. 8 years). Ethnicities were: 1. Caucasians, two Asians, two African American, and one Hispanic. The groups did not differ in age (t (2. The study protocol was approved by the IRBs of Massachusetts General Hospital and the University of Massachusetts Medical School, and written informed consent was obtained from all participants. A previous publication that investigated neural correlates of changes in perceived stress (H. Briefly, it consists of eight weekly group meetings lasting two and a half hours each, plus one full day (6. Formal mindfulness training exercises aim at developing the capacity for mindfulness (awareness of present- moment experiences with a compassionate, non- judgmental stance) and include a body scan, mindful yoga, and sitting meditation. During the body scan attention is sequentially guided through the entire body, observing with non- judgmental awareness the sensations in each region and ending with an awareness of the body “as a complete whole”. The mindful yoga typically contains gentle stretching exercises and slow movements that are often coordinated with the breath, with emphasis placed on bringing full awareness to the moment- to- moment experience and a non- harming attitude towards the body. Participants are encouraged to investigate what feels appropriate for themselves and to honor their body’s limitations. Sitting meditation practices typically begin with awareness of the sensations of breathing, then evolve to include awareness of different modalities (such as sounds, sight, taste, other body sensations, thoughts and emotions). Later, emphasis is given to open awareness meditation, where the field of awareness is expanded to include anything that appears in consciousness, or a simple awareness of one’s presence in the here and now. Participants received audio recordings containing 4. To facilitate the integration of mindfulness into daily life, they were also taught to practice mindfulness informally in everyday activities such as eating, walking, washing the dishes, taking a shower etc. During classes the formal mindfulness exercises were practiced, questions relating to the practice of mindfulness in everyday life were clarified and didactic instruction given on using mindfulness for coping with stress in daily life. Historically, MBSR participants have reported a wide range of home practice compliance and for this reason study participants recorded the amount of time they spent engaged in mindfulness exercises each day. Five facet mindfulness questionnaire. The Five Facet Mindfulness Questionnaire (FFMQ; Baer et al., 2. Observing (attending to or noticing internal and external stimuli, such as sensations, emotions, cognitions, sights, sounds, and smells), describing (noting or mentally labeling these stimuli with words), acting with awareness (attending to one’s current actions, as opposed to behaving automatically or absent- mindedly), non- judging of inner experience (refraining from evaluation of one’s sensations, cognitions, and emotions) and non- reactivity to inner experience (allowing thoughts and feeling to come and go, without attention getting caught up in them). Responses to the items are given on a 5- point Likert- type scale (1 = never or very rarely true, 5 = very often or always true).
