This study proposes to design and build a neural imager/stimulator which will let us obtain information about brain circuits and pathways by acquiring electrical and fMRI signals from the brain at the same time. By adding magnetic stimulation to the instrument we will be able to perturb these circuits at precise times and locations in order to both improve how TMS is used as an anti-depression treatment as well as to better understand how our brains function. This research has the potential to revolutionize our understanding of how best to use TMS as a treatment as well as learning how our brains function. This study simply proposes to develop the combined instrument. The use of the new instrument as a anti-depressive treatment will be presented independently after we have developed a working instrument.
This study will compare the safety and effectiveness of a new facemask, the Tao mask, as compared to the standard mask for manual ventilation of patients with BMIs of 40 or greater who are undergoing elective surgery. The Tao mask and the standard mask will both be used for each patient but the order of evaluating the masks will be randomized.
This study will examine the effects of early childhood adversity on stress and craving among individuals with opioid use disorder. Study participants will complete a total of three visits, including a 1-month follow-up visit. Participants will be asked to complete questionnaires about thier mood, anxiety, drug use, craving and adverse childhood events. They will listen to personalized scripts about a stressful situation, a time when they used opioid and a relaxing situation and their heart rate, skin conductance and cortisol are measured.
