What the study is about

The goal of this study is to determine whether stimulation of the brain-stomach connection can influence stomach activity in healthy adults and in individuals suffering from chronic nausea. The main questions it aims to answer are:

  • What are the best brain sites to influence the stomach?
  • What are the effects of different stimulation patterns on stomach activity?
  • Does the stimulation affect the sensation of nausea in participants suffering from chronic nausea?

Researchers will use a non-invasive method of brain stimulation called Transcranial Magnetic Stimulation (TMS) and will record stomach responses with skin electrodes on the abdomen.

Participants will

  • Visit the clinic at least once, and for up to 9 times more over the course of several months.
  • Receive TMS while sitting in a chair similar to a dentist's chair.
  • Drink water or consume a test meal during each study visit.

Being studied: Transcranial Magnetic Stimulation, TMS

Conditions: Chronic Nausea and Vomiting Syndrome

Exclusion Criteria

  • body mass index (BMI) > 30
  • pregnancy or intention to become pregnant
  • past or present chemotherapy
  • diagnosis of gastric (stomach) cancer
  • any kind of gastric (stomach) surgery
  • current use of GLP-1 receptor agonists (e.g. Ozempic, Trulicity)
  • medications which significantly lower seizure thresholds (e.g. bupropion (Wellbutrin), fluoxetine (Prozac), or tramadol (Ultram))
  • implantable devices, such as a pacemakers or nerve stimulators
  • history of head injury that required hospitalization, metal in the skull, or neurologic disease such as stroke, history of seizures or history of syncope (fainting or passing out)
  • neurodegenerative disease (Multiple Sclerosis, Parkinson's or Alzheimer's Disease)
  • ongoing psychosis or altered cognitive status status (e.g. hearing sounds or seeing visions that are not there, or feeling confused or suffering from memory lapses)
  • history of cardiovascular (i.e., heart attack), pulmonary (i.e., need for supplemental oxygen), or endocrine disease (e.g. diabetes)
  • current enrollment in another study using Transcranial Magnetic Stimulation (TMS)
  • current use of drugs such as amphetamines, methamphetamine, Ecstasy, Ketamine, Angel Dust/PCP, cocaine, or drinking 3 or more alcoholic drinks per day
  • For healthy subjects only: chronic history of gastrointestinal symptoms (e.g., nausea, indigestion, bloating, abdominal pain)
  • For CNVS subjects only: diagnosis of gastric motility disorder (e.g. gastroparesis/slow stomach emptying) or history of bowel obstruction (i.e., chronic partial small bowel obstruction)
