Objective: The underlying changes in biological processes that are associated with reported changes in mental and physical health in response to meditation have not been systematically explored. We performed a randomized, controlled study on the effects on brain and immune function of a well-known and widely used 8-week clinical training program in mindfulness meditation applied in a work environment with healthy employees. Methods: We measured brain electrical activity before and immediately after, and then 4 months after an 8-week training program in mindfulness meditation. Twenty-five subjects were tested in the meditation group. A wait-list control group (N 16) was tested at the same points in time as the meditators. At the end of the 8-week period, subjects in both groups were vaccinated with influenza vaccine. Results: We report for the first time significant increases in left-sided anterior activation, a pattern previously associated with positive affect, in the meditators compared with the nonmeditators. We also found significant increases in antibody titers to influenza vaccine among subjects in the meditation compared with those in the wait-list control group. Finally, the magnitude of increase in left-sided activation predicted the magnitude of antibody titer rise to the vaccine. Conclusions: These findings demonstrate that a short program in mindfulness meditation produces demonstrable effects on brain and immune function. These findings suggest that meditation may change brain and immune function in positive ways and underscore the need for additional research.

W INTRODUCTION ith the widespread and growing use of meditative practices in hospitals and academic medical centers for outpatients presenting with a range of chronic stress and pain-related disorders and chronic diseases, under the umbrella of what has come to be called mind/body or integrative medicine, the question of possible biological mechanisms by which meditation may affect somatic, cognitive, and affective processes becomes increasingly important. Research on the biological concomitants of meditation practice is sparse and has mostly focused on changes that occur during a period of meditation compared with a resting control condition in a single experimental session (13). Whereas these studies have been informative, they tell us little about changes that are potentially more enduring. Moreover, virtually all forms of meditation profess to alter everyday behavior, effects that are by definition not restricted to the times during which formal From Laboratory for Affective Neuroscience (R.J.D., J.S., M.R.), Department of Psychology, University of Wisconsin, Madison, Wisconsin; Stress Reduction Clinic, Division of Preventive and Behavioral Medicine (J.K.-Z., S.F.S., F.U.), Department of Medicine, University of Massachusetts Medical School, Worcester, Massachusetts; Departments of Medicine and Microbiology (D.M.), University of Wisconsin Medical School; Department of the History of Science (A.H.), Harvard University, Cambridge, Massachusetts; Departments of Preventive Cardiology and Sports Medicine (K.B.), University of Wisconsin-Madison Hospitals and Clinics Center for Mindfulness, Madison, Wisconsin; and Department of Oral Biology (J.F.S.), College of Dentistry, Ohio State University, Columbus, Ohio.

Thus, in the current report, we focus not on the period of meditation itself, but rather on the more enduring changes that can be detected in baseline brain function as well as brain activity in response to specific emotional challenges. We focus on emotion-related brain activity because meditation has been found in numerous studies to reduce anxiety and increase positive affect (4 8). In an extensive corpus of work on the functional neuroanatomical substrates of emotion and affective style, we have established that the frontal regions of the brain exhibit a specialization for certain forms of positive and negative emotion (9, 10). Left-sided activation in several anterior regions is observed during certain forms of positive emotion and in subjects with more dispositional positive affect (10, 11). We therefore hypothesized that because meditation decreases anxiety and increases positive affect, subjects who were practicing meditation should show increased left-sided activation in these territories compared with those in a wait-list control group. Recent studies have established that greater relative leftsided anterior activation at baseline is associated with enhanced immune function using measures of NK activity (12, 13). There has been a paucity of serious research attention to possible immune alterations that might be produced by meditation (14). This is somewhat surprising in light of the fact that negative psychosocial influences on immunity have now been well established (1517). Recent research indicates that relaxation and stress management procedures increase T-cytotoxic/suppressor (CD3 CD) lymphocytes in HIV-infected men (18). On the basis of recent research demonstrating the negative impact of stressful life events on antibody titers in response to influenza vaccine (19), we vaccinated all subjects at the end of the 8-week meditation program (in mid November), along with the subjects in wait-list control group at the same time. We hypothesized that the meditators would show greater antibody titers in response to the vaccine compared with the subjects in the wait-list control group. On the basis of
