• Testing a new sensor for measuring brain activity

  This study is testing a new sensor to see if it can measure brain activity better than traditional methods in healthy adults aged 18-65.

  Recruiting National Institutes of Health Clinical Center (CC) · Bethesda, Maryland · NCT04950309

• Exploring how healthy brains process sights and sounds

  This study is testing how healthy brains understand sights and sounds by having people aged 13-65 complete different tasks while using brain imaging techniques.

  Recruiting at 2 sites National Institutes of Health Clinical Center (CC) · Bethesda, Maryland and 1 other locations · NCT03407066

• Exploring how brain stimulation affects movement after stroke

  This study tests if a type of brain stimulation can help improve movement in people who have had a stroke and healthy adults by looking at how timing affects the results.

  Recruiting National Institutes of Health Clinical Center (CC) · Bethesda, Maryland · NCT03288220

• Exploring how social factors influence pain expression and assessment

  This study is trying to see how social factors affect how people show and report pain, especially in disadvantaged groups, to find better ways to assess and treat pain fairly.

  Recruiting National Institutes of Health Clinical Center (CC) · Bethesda, Maryland · NCT03258580

• Understanding pain and its disorders through participant experiences

  This study is trying to understand how people experience pain by looking at both those with pain disorders and those without, to help improve future pain research.

  Recruiting National Institutes of Health Clinical Center (CC) · Bethesda, Maryland · NCT02707029

• Study of brain activity during sleep using fMRI and EEG

  This study is testing how the brain reacts to sounds while we sleep by using special scans on healthy young adults to learn more about sleep and brain connections.

  Recruiting National Institutes of Health Clinical Center (CC) · Bethesda, Maryland · NCT02629107

• Understanding how pain and emotions are processed in the brain

  This study is trying to see how our brain processes pain and emotions and how things like expectations and social factors can change our experience of pain in healthy volunteers.

  Recruiting National Institutes of Health Clinical Center (CC) · Bethesda, Maryland · NCT02446262

• Development of advanced MRI techniques for healthy individuals

  This study is testing new MRI techniques on healthy volunteers to help improve imaging methods for future medical research.

Quick answers

How many Normal Physiology clinical trials are recruiting right now?

20, as of November 12, 2026. We update this list each time we refresh our data from ClinicalTrials.gov.

Where are these trials running?

In 3 countries. The most sites are in United States (18 trials), China (1 trial), Canada (1 trial). Each study page lists its sites and which ones are recruiting.

What phases are they in?

Early Phase 1: 1. Trials with no phase listed are usually device, behavioural or observational studies.

How do I join one?

Open a study, check the "Is this trial a fit for you?" section, then contact the study team listed on the page. They will ask a few screening questions. Asking is free and does not commit you to anything. Talk it over with your doctor first.
