This study tests a type of brain stimulation in people with epilepsy to see if it can help preserve memory. Researchers will compare memory and brain effects over time to understand whether stimulation changes memory outcomes.
Rochester, MinnesotaAges 18–65 - NCT05419713Recruiting
Test of how the brain processes depth and space
This study tests how people perceive depth and space using visual tasks. It may help researchers better understand normal (or well-corrected) vision and how the brain handles visual information.
Louisville, KentuckyAges 18–40 - NCT05265546RecruitingPhase 1
Psilocybin study of changes in how you see
This Phase 1 study tests whether psilocybin affects visual perception and how visual information is represented in the brain. It also studies safety and what brain/vision changes happen after the dose.
Berkeley, CaliforniaAges 21 years+ - NCT05252312Recruiting
Study of how nonverbal sounds affect your body
This study looks at how nonverbal acoustic (sound) signals affect normal body responses. You may be able to join if you can complete the sound-related tasks and don’t have conditions that could interfere with hearing or speaking.

Study how each brain side helps you understand speech
This study looks at how the left and right sides of the brain help with speech understanding, using a safe brain-stimulation method called TMS. It may help researchers understand why some people struggle with speech and communication.

STANISLAS cohort follow-up visit for heart and kidney health
This study is a follow-up visit for people who joined the STANISLAS family health cohort. Researchers look at how genes and environment may affect heart and kidney (kidneys) health over time.
Vandœuvre-lès-Nancy, LorraineAges Any age - NCT07873567Recruiting
Ergonomic risks and muscle pain in midwifery students
This study looks at how common muscle and joint discomfort is among midwifery students and what work-related factors might contribute to it. Your answers may help improve training and work environments for future midwives.
MardinAges 18 years+ - NCT07853807Recruiting
Thinking and memory study for adults with schizophrenia and healthy volunteers
This study uses computer tasks to learn how people with schizophrenia think, pay attention, and remember. It may help improve future tests and treatments for schizophrenia. Healthy volunteers are also needed to compare results.
Irvine, CaliforniaAges 18–59 - NCT07860281Recruiting
Brain scans to study memory and perception
This study uses brain imaging (fMRI) to learn how memory and perception work in healthy people. Participating involves brain scans while you perform simple tasks, which may help scientists understand how the brain processes information.
Tallahassee, FloridaAges 18–35 - NCT03655782Recruiting
Retraining brain pathways to improve memory after mild brain injury
This study tests a computer-based brain training program that may help improve memory and thinking skills in people who have had a mild traumatic brain injury or concussion. The training involves watching moving stripes on a screen and using arrow keys to respond, which is designed to retrain brain pathways.
San Diego, CaliforniaAges 18–60 - NCT07869407Recruiting
Painless cavity filling: new tools vs traditional drill
This trial compares two newer methods for removing tooth decay (smart burs and a dissolving gel called Carisolv) to the traditional drill, to see which causes less pain during the procedure. It may help find a more comfortable way to treat cavities.
Peshawar, Khyber PakhtunkhwaAges 18–45 - NCT07868705Enrolling by invitation
Comparing small screws for braces in the upper jaw
This study compares two sizes of tiny screws (called miniscrews) that are sometimes used with braces to help move teeth. The screws are placed in the upper jaw to help correct an overbite where the top teeth stick out too far. The study looks at how well the screws work, how stable they are, and how they feel to patients.
Kuala LumpurAges 13–50 - NCT07864285Recruiting
Occupational doctors' knowledge of premenstrual dysphoric disorder
This study asks occupational doctors in France about their knowledge and handling of premenstrual dysphoric disorder (PMDD), a severe form of PMS. It aims to improve workplace support for women with PMDD.
StrasbourgAges 18 years+ - NCT05458037Recruiting
Testing fast versus slow numbing during IUD or biopsy
This study compares two ways of applying a numbing tool (“tenaculum”) during an IUD insertion or an endometrial biopsy to see which one causes less pain. If you’re scheduled for one of these procedures, it may help improve how discomfort is managed.
Providence, Rhode IslandAges 18 years+ - NCT07846241Recruiting
Sexual behavior and risk of infections in young adults
This study looks at how young adults' sexual behavior and risk perception relate to getting sexually transmitted infections (STIs). By participating, you'll help researchers better understand how to prevent STIs in people your age.
BarcelonaAges 18–25 - NCT07846501Enrolling by invitation
How thoughts and feelings affect fibromyalgia impact
This study looks at how your thoughts, emotions, and attitudes about your illness affect how fibromyalgia impacts your daily life. By filling out questionnaires, you can help doctors understand what matters most to people with fibromyalgia.
Bilecik, BilecikAges 18 years+ - NCT07835191Recruiting
Cooling and sweet solution to ease dental shot pain in children
This study tests whether cooling the injection site and using a sweet-tasting solution before the dental numbing shot can reduce pain for children aged 7 to 11. If your child needs a dental procedure requiring a local anesthetic injection, this might help make the experience more comfortable.
Cairo, El SheroukAges 7–11 - NCT06340438Recruiting
Itch and thoughts: a healthy volunteer study
This study looks at how your thoughts (specifically, catastrophizing) affect how intensely you feel itch. Healthy volunteers are asked to rate itch sensations after a mild stimulus, helping researchers understand the connection between thinking and feeling.

Common questions
- Are there clinical trials for perception?
- Yes. Clin2 currently lists 210 recruiting perception studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a perception trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a perception trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
