A Pilot Study Investigating Transcranial Direct Current Stimulation (tDCS) to Enhance Mindfulness Meditation
The purpose of this study is to determine if a new technology applied while listening to a mindfulness meditation tape can affect one's ability to achieve a state of "mindfulness." The new technology is called transcranial direct current stimulation, or tDCS.
Many people initially attempt meditation but cannot get their mind to be still. Or they do not get quick results and find it frustrating. Thus, the number of people benefiting from meditation would increase if there were a method of making it easier to perform. Moreover, establishing the actual brain mechanisms involved in the benefits of meditation would potentially open up synergistic treatments and approaches.
The investigators will investigate the use of a new, non-invasive brain stimulation method called transcranial direct current stimulation (tDCS) to augment a state of mindfulness. tDCS is a safe, inexpensive, non-invasive brain stimulation modality that has the capability of focally increasing or decreasing cortical activity. Anodal stimulation produces positive DC stimulation and is associated with increased cortical activity, whereas Cathodal stimulation produces a negative DC stimulation and is associated with decreased cortical activity. Cortical activity changes occur both during and after stimulation in a dose response fashion (higher current density and longer duration of stimulation produces larger and longer lasting effects).
The investigators will be investigating the use of tDCS to augment mindfulness meditation in a double-blind, crossover, randomized, sham-controlled trial.
