The purpose of this research study is to examine the effect of a brain stimulation training to improve the function of brain-spinal cord- muscle connections.Because brain-to-muscle pathways are very important in our movement control, restoring function of these pathways may improve movement problems after injuries. Spinal cord injury causes damage to the brain-to-muscle connection. However, when the injury is "incomplete", there is a possibility that some of the brain-to-muscle pathways are still connected and may be trained to improve movement function. For examining brain-to-muscle pathways, we use a transcranial magnetic stimulator. We hope that the results of this research study will help us develop new treatments for people who have movement disabilities. This study will require about 42 visits over the first 14 weeks, and another 6 visits over an additional 3 months. Each visit will take about 1 ½ hours.

Apathy is a common set of symptoms seen in many people following a stroke. Apathy occurs when a person has lost motivation, becomes withdrawn, and stops doing things that used to be important to them. Apathy has a large negative impact on a person's quality of life, and can also have a large impact the people who take care of individuals with apathy. There are currently no FDA-approved treatments to help with apathy, and other services like therapy may be difficult to access for people who have had a stroke. To address this problem, we are conducting a study to find out if a form of treatment called repetitive transcranial magnetic stimulation (rTMS) can be safe and helpful for people struggling with apathy after a stroke. Our study will apply a new form of rTMS which can be delivered quickly to a part of the brain called the medial prefrontal cortex (mPFC). Our study will help establish whether this treatment is safe, comfortable, and effective for people with apathy after a stroke, and will help researchers develop new forms of treatment.

The purpose of this study is to explore whether 4 weeks of at-home transcutaneous auricular neurostimulation (tAN) can reduce chronic pain after a stroke. We will recruit up to 24 participants with chronic post-stroke upper extremity pain. The goal is to determine if there is a pain reduction after ear stimulation.

As growing research suggests noninvasive brain stimulation techniques have the potential to adjunct current treatments or treat Seizure-Type Functional Neurologic Disorder (FND-seiz), also known as Psychogenic Non-Epileptic Seizures (PNES), we aim to evaluate whether a form of accelerated intermittent theta burst transcranial magnetic stimulation (a-iTBS-rTMS), is a practical and well-tolerated treatment for people with this disorder. Transcranial Magnetic Stimulation or TMS uses magnetic pulses to stimulate a part of the brain involved in mood and thinking, the left dorsolateral prefrontal cortex, which has established benefits in disorders known to coincide in patients with FND-seiz, such as depression.

As an open-label, early feasibility study, enrolled participants will receive 6 to 10 treatment sessions each day over 3 to 5 days, with the goal of completing 30 total sessions. This approach was selected because similar protocols have already been shown to be safe and effective in other conditions, and the shortened treatment schedule in comparison to other protocols may make participation easier for people living with FND-seiz. The main goal of the study is to see how many participants can safely and comfortably complete at least 20 of the 30 TMS sessions.

The researchers will also evaluate changes in seizure frequency, quality of life, mood, post-traumatic stress symptoms, physical health, social functioning, and overall satisfaction with treatment. These outcomes will be measured before treatment and again four weeks afterward. The researchers also aim to explore whether people with overlapping conditions, such as depression or PTSD, respond differently to the treatment. Finally, given the overlap between epilepsy and FND-seiz, not all TMS providers are comfortable treating patients with FND-seiz when TMS is indicated for other conditions, thus the researchers aim to outline a protocol to ensure safety and increase TMS access for FND-seiz patients.

Patients with drug-resistant epilepsy often experience problems with mood, thinking, or behavior that cannot be explained by seizure activity alone. This study will examine how cognitive and mood-related brain regions communicate in patients undergoing routine intracranial electroencephalogram (iEEG) seizure assessment in the Epilepsy Monitoring Unit at the Medical University of South Carolina (MUSC). While the clinical electrodes are in place, we will apply brief single magnetic pulses (single-pulse transcranial magnetic stimulation, or spTMS) to the scalp in specific brain regions and record the brain's electrical response through the existing electrodes; no additional surgery is required. We will compare the responses to stimulation of an emotionally and cognitively relevant region (left dorsolateral prefrontal cortex) with a contrast site (primary motor cortex). We will also investigate whether momentary brain rhythms and seizure-related electrical activity affect responses propagation through the brain. The findings may help identify measurable brain signaling patterns ("biomarkers") to understand how cognitive-emotional brain networks work in people with epilepsy and inform future personalized non-invasive brain stimulation methods for treating neurological and psychiatric disorders.

Newborns who are born premature or infants who suffer brain injury are at risk for motor problems. The common motor skills of reaching and grasping that infants have to learn can be weaker on one side of the body, depending on the site of the brain injury. These skills are routinely practiced with an occupational therapist once or twice a week, to help the infant strengthen these skills. A high intensity therapy program of constraint induced movement therapy (CIMT) may be available for the infant, but it takes from 40-120 hours total treatment time for most infants to improve their motor skills.
Transcutaneous auricular vagus nerve stimulation (taVNS) stimulates a branch of a major nerve by the ear, called the vagus nerve, that may help improve your child's ability to learn motor skills. CIMT involves placing a soft mitt constraint on the stronger arm and hand while encouraging your child to use the weaker arm and hand during intensive therapy sessions. By using both CIMT and the nerve stimulation together, we hope your child's movement skills will improve more than with therapy alone.
The purpose of this study is to evaluate the safety and effectiveness of taVNS to improve motor skills when paired with the minimal amount of CIMT and whether a measure of the strength of the brain circuit to the arm and hand muscles can tell us how well a child may respond to this therapy.

Preterm and term infants with brain injury frequently have difficulty learning to feed by mouth. Transcutaneous vagus nerve stimulation (taVNS) may be paired with the motor activity of feeding to boost brain circuits involved with feeding. This study will test a taVNS-paired bottle system in a blinded, randomized, controlled trial in infants who have reached term age and failed to learn to feed. Our preliminary data indicates that most infants improve their volume of oral feeds with the BabySTrong system, and 50-70% achieve full oral feeds and avoid placement of a gastrostomy tube (G-tube) or home nasogastric tube. The BabySTrong feeding system may improve oral feeding volumes and help infants and their families avoid a long hospital stay while trying to learn to feed.

In this study, we are testing whether a higher dose of a non-invasive brain stimulation technique, called transcranial direct current stimulation (tDCS), can be safely used in people with depression. Participants will come to the Brain Stimulation Lab and receive mild electrical stimulation through electrodes placed on their scalp.

The study begins with a safety run-in, where the first few participants will receive stimulation at gradually increasing levels (2, 4, and 6 milliamps) while being closely monitored. If no serious side effects are found, later participants will receive repeated 6 milliamp sessions for 5 days total. We will check skin comfort, mood, and overall tolerability after each session.

Deep brain stimulation (DBS) is a surgical treatment that can help improve the symptoms of Parkinson's disease (PD). However, the effectiveness of this treatment varies among patients, and physicians currently have no way to predict who will benefit the most. This study will investigate whether the types of bacteria in a person's gut can help predict their response to DBS. By analyzing patient samples, we aim to identify biomarkers that could help doctors better select candidates for this procedure, ultimately leading to more successful treatment outcomes for individuals with Parkinson's disease.

The purpose of this study to help us understand if adding transcranial Direct Current
Stimulation (tDCS), a non-invasive brain stimulation technique, to Speech Therapy
improves language recovery in people with Broca's aphasia and is more effective than Speech Therapy alone.
