Summary

This study will examine the neural circuitry associated with craving, behavioral disinhibition, and threat-reactivity. The study will involve 2 visits. During the first visit, participants will complete questionnaires and interviews in a private room and do some tests to measure alcohol use. During the second visit, participants will complete a neuroimaging scan of their brain.

Summary

Transcranial magnetic stimulation (TMS), a non-invasive form of brain stimulation, produces lasting changes in the brain to treat depression and other brain disorders. Emphasis on clinical indications and efficacy has far outpaced a mechanistic understanding of how these changes are produced. In this study, we propose use of the pharmacologic agents d-cycloserine, demonstrated to be safe for human use, to probe in the molecular mechanism of long-term potentiation, the cellular basis of learning and memory. We will measure whether this agent can respectively strengthen the potentiation produced by TMS by looking at the amplitude of motor response (called motor evoked potential or MEP) of the thumb (through electromyography, or EMG).
A better understanding of its mechanism of action promises to optimize our ability to use TMS, and potentially improve duration and degree of response.

Summary

The purpose of this study is to develop a non-invasive form of brain stimulation called transcranial magnetic stimulation (TMS), specifically TMS at a frequency known as theta burst stimulation (TBS), as a potential treatment to food related cravings. TBS is a technique that uses magnetic pulses to temporarily stimulate specific brain areas in awake people (without the need for surgery, anesthetic, or other invasive procedures). This study will test whether TBS over the prefrontal cortex can produce a reduction in responses to food cues. This will be examined through behavioral assessments and functional MRI's given before and after TBS administration. TMS has been approved by the FDA as an investigational tool as well a therapy for depression. However, TMS is not currently approved by the Food and Drug Administration as a treatment for food related cravings, eating disorders, or addictions.

Summary

Prospective trial with enrollment of 30 patients in various intensive care units at Palmetto Health Richland from January 1st 2019 to June 30th 2020. If patients had undergone targeted temperature management (33-36 degrees Celsius for 24 hours via intravascular or surface control methods, with or without sedation or neuromuscular blockade, followed by rewarming actively or passively at 0.25-0.5 degrees per hour over 8-12 hours to 37 degrees) investigators will wait 24 hours after rewarming prior to testing. End point is to evaluate if pharmacological reversal agents would result in improved GCS scores or return of cerebral or brainstem functions in some comatose patients, which will be considered a positive test result.

Age-related changes in neuroplasticity impede recovery in post-stroke depression: a novel exercise and brain stimulation paradigm to prime neuroplastic potential Save

Summary

Stroke affects millions of Americans and is a leading cause of disability. In addition to chronic disability, many survivors experience depressive symptoms such as reductions in mood and motivation. Post-stroke depression (PSD) is associated with poorer recovery from stroke, increased health care costs and higher mortality. Additionally, PSD may interfere with the recovery of the nervous system after stroke. Effective treatment options for PSD are limited and often come with side effects, highlighting the need for alternative treatment approaches. Aerobic exercise (AEx) has positive effects on the nervous system, is a powerful anti-depressant, and has limited side effects, yet remains underutilized in stroke survivors with PSD. This study will examine the short-term effects of AEx on the nervous system in stroke survivors with and without PSD. The results will serve as a foundation for the study of AEx as a treatment for PSD.

Summary

Traumatic Brain Injury is a risk factor for Alzheimer's Disease and other dementias. This study will use neuroimaging in Veterans and civilians with a history of TBI or without TBI to understand whether some of the brain changes that occur in Alzheimer's Disease are present in people with a history of TBI. The study is recruiting male and female military Veterans or civilians with or without TBI between the ages of 18 and 64.

Summary

The purpose of this study is to develop transcranial magnetic stimulation (TMS) as a novel, non-pharmacologic approach to decreasing pain in individuals with chronic pain. This study will test whether rTMS over the prefrontal cortex can produce a reduction in your perception of pain, your desire to use opiates, and your brain's response to opiate cues. The results of this study will be used to design and develop a large clinical trial of rTMS as an innovative, new treatment option for chronic lower back pain in individuals that may have used chronic opiates.

Summary

Transcranial direct current stimulation (tDCS) has shown the potential to improve symptoms in patients with motor deficits, however its effects have not been consistent in randomized studies to date, limiting widespread adoption of this technology. A critical gap in our knowledge is a detailed understanding of how tDCS affects motor areas in the brain. We propose using tDCS while recording directly from motor cortex using subdural electrocorticography (sECoG) in patients undergoing deep brain stimulation surgery. We expect this novel approach to broaden our understanding of tDCS application and possibly lead to therapeutic advances in this population.

Summary

This Charleston Alcohol Research Center (ARC) pilot study seeks to provide the preliminary validation of a novel natural rewards fMRI paradigm which may be used in the development and/or evaluation of alcohol addiction medication treatments. Specifically, individuals with alcohol use disorder (AUD) and social drinkers will be recruited for a magnetic resonance imaging (MRI) study which will include magnetic resonance spectroscopy, an alcohol cue task, and this novel natural rewards paradigm which examines brain response to social reward and food. Invited participants will complete an initial screening diagnostic assessment visit at the Medical University of South Carolina, which will consist of clinical interviews with research staff, questionnaires, and labs. If still eligible, participants will be invited for a second appointment which will include additional clinical measures, questionnaires, and an MRI scan. This study is confidential and participants will be compensated for participating.
