With recently discharged veterans from Operation Iraqi Freedom (OIF) as our subjects, this study examines the neuroanatomical underpinnings as well as cognitive and perceptual biases associated with the progression of early onset Posttraumatic Stress Disorder (PTSD). We are comparing the efficacy of Mindfulness-Based Stress Reduction (MBSR; treatment) to Supportive Therapy (ST; control) as early interventions …

This study uses a rigorous interdisciplinary approach to analyze EEG data collected during two 3-month long intensive meditation retreats in four steps. First, novel tools were developed for preprocessing the EEG data. Second, in order to identify the cortical correlates of meditation, longitudinal changes in the cortical activity were measured using spectral analysis. Three main …
The practice of meditative concentration has been proposed to be somewhat equivalent to an attention task. Because the attention and working memory systems are intimately linked, we hypothesized that practicing this particular attention task would make the working memory system more efficient. We tested 29 participants of a Dathun (a month-long intensive meditation retreat), before …

Previous emotion regulation studies (Ochsner et al., 2004, Urry et al., 2006) have used reappraisal as a strategy to investigate neural mechanisms of down-regulating negative emotion. Compassion may also be viewed as a regulatory strategy to cope with negative emotion, which may differ in neural mechanism and positive behavioral outcomes. In a pilot study, we investigate …
Research on the effects of meditation has focused on understanding both the meditative state as well as characteristics resulting from long-term, regular meditation practice. Understanding these states and traits is of interest because of potential clinical applications and the possibility for better understanding of brain states and function. In particular, this is of interest for …
Previous studies have indicated that mindfulness and other forms of meditation training are associated with improvements in sleep quality. However, none of these studies used objective polysomnographic sleep recordings. The aim of this study was to examine whether mindfulness meditation was associated with improvements in objectively measured sleep, according to polysomnography (PSG), and to relate …
Mindfulness‐Based Stress Reduction (MBSR) is an 8 week course that teaches participants to change their patterns of reacting to stress. To accomplish this goal, participants practice meditation to increase their ability to attend to emotions and develop the ability to attend to their patterns of reactivity. In theory, this awareness will eventually enable participants to …

Prior studies have focused on the impact of mindfulness-based interventions on alleviating physical or psychological symptoms or difficulties (e.g., Teasdale et al., 2000; Ma & Teasdale, 2004), or on enhancing positive states, including mindfulness itself (E.g., Brown & Ryan, 2003). Relatively little work has focused on cognitive measures that might reflect the presence or absence …
The effect of meditation on pain perception was investigated. Zen meditators and controls were instructed to attend, in different ways, to painful and non-painful thermal stimuli. Conditions included: a) baseline, b) concentration: attend exclusively to the left calf, c) mindfulness: attend to the left calf and observe, moment to moment, in a non-judgmental manner. Meditators …

Human neuroimaging offers a powerful way to connect animal and human research on emotion, with profound implications for psychological science. However, the gulf between animal and human studies remains a formidable obstacle: Human studies typically focus on the cortex and a few subcortical regions such as the amygdala, whereas deeper structures such as the brainstem …
