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.

In this research study, we are examining how brain activity (electrical and blood flow) changes during tests of emotional processing and attention and memory in the magnetic resonance imaging (MRI) scanner. We are also using non-invasive brain stimulation to probe different parts of the brain and measuring brain activity (electrical and blood flow) alongside evidence-based cognitive behavioural therapy. This study includes healthy and clinical participants and researchers hope this will help us develop improved brain-based treatments for emotional difficulties like depression.

Alcohol misuse is a risk factor for early onset cognitive impairment, contributing to 10% of early onset dementia, with risk corresponding to consumption. Additionally, continued drinking risks worsening cognitive decline and dementia progression, while worsening cognitive impairment contributes to drinking escalation. Repetitive transcranial magnetic stimulation (rTMS) has been shown to improve cognition in Alzheimer's Disease and Related Dimentias (ADRD) and separately reduce heavy drinking in alcohol use disorder. Our objective is to optimize rTMS for simultaneous mitigation of both drinking and cognitive dysfunction in older adults.

The purpose of this study is to identify domains in which stroke suvivors may have struggled since experiencing a stroke. These include things like emotional, family and work function. This study entails an interview and questionnaires that ask about functioning in these areas.

The longer-term goal of this work is to identify areas these areas so that we can develop a psychotherapy that could be helpful for individuals recovering from and living with the aftermath of stroke.

The purpose of this study is to develop transcranial magnetic stimulation (TMS), specifically TMS at a frequency known as theta burst stimulation (TBS), to see how it affects the brain and changes the brain's response to alcohol-related pictures. TMS and TBS are stimulation techniques that use magnetic pulses to temporarily excite specific brain areas in awake people (without the need for surgery, anesthetic, or other invasive procedures). TBS, which is a form of TMS, will be applied over the medial prefrontal cortex, (MPFC), which has been shown to be involved with drinking patterns and alcohol consumption. This study will test whether TBS can be used as an alternative tool to reduce the desire to use alcohol and reducing the brain's response to alcohol-related pictures.
