Recruiting studies
- NCT06691087Recruiting

Brain study of social perception in Parkinson's disease
This study uses brain scans to understand how people with Parkinson's disease process social cues, like faces and emotions. It may help researchers learn more about how Parkinson's affects social thinking.
BronAges 30–75 - NCT07682311Recruiting
Adjusting brain stimulation automatically for Parkinson's
This study tests a new way to adjust deep brain stimulation (DBS) automatically during the day to better control Parkinson's symptoms. It is for people who already have a Percept DBS device but still have motor fluctuations.
San Francisco, CaliforniaAges 25–75 - NCT07398157Recruiting
24-hour adaptive deep brain stimulation for Parkinson's
This trial tests a new deep brain stimulation system that adapts in real time to improve symptom control over 24 hours, especially for people with daytime fluctuations or sleep problems despite standard DBS.
San Francisco, CaliforniaAges 18 years+ - NCT07089953Recruiting
Does the doctor's computer use affect your visit?
This study looks at whether a small change in how doctors use electronic health records can improve how compassionate and professional they seem during your clinic visit. If you join, you would fill out a short survey after your appointment.
Houston, TexasAges 18 years+ - 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 - NCT04989309Enrolling by invitation
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.
Storrs, ConnecticutAges 18 years+ - NCT05417542Recruiting
Study how young brains hear rhythms
This study looks at how babies’ brains process rhythm and sound. It may help researchers understand early brain development, especially from premature birth through infancy.
AmiensAges birth–18 years - 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+ - NCT04290130Enrolling by invitation
Study brain signals during audiovisual speech in neurosurgery patients
This study measures brain activity to understand how your brain combines what you see and hear during speech. It may help scientists build better ways to understand and treat problems with speech processing.
Philadelphia, PennsylvaniaAges 21–65 - NCT06841601Recruiting
Shaking or cold for less pain during dental shots
This trial tests whether a vibrating tool or a cold pack can help reduce pain when children get a numbing shot at the dentist. If your child needs a simple filling and is generally healthy, this study might help make their experience more comfortable.
AlexandriaAges 5–9 - NCT05837039Recruiting
Comparing caregiver and nurse views of discomfort in advanced cancer
This study compares how healthcare providers and family caregivers judge discomfort in people with advanced cancer who are very hard to rouse and may be actively dying. It aims to understand whether caregiver and staff perceptions match, which could improve comfort care for patients near the end of life.
Houston, TexasAges 18 years+ - NCT05608408Recruiting
Preserving Memory in People With Epilepsy Using Brain Stimulation
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 - NCT07148921Recruiting
Pain perception during gender affirming hormone therapy
This study looks at how starting gender affirming hormone therapy may change your experience of pain. If you are an adult assigned female at birth planning to start testosterone, or an adult assigned male at birth planning to start estradiol, and you have not taken any sex hormones in the past six months, this trial wants to measure your pain perception over time.
Vienna, State of ViennaAges 18 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.
Saint-EtienneAges 18–80 - NCT05468567Recruiting
Sound perception study for people with noise-related ear injury
This study looks at how people who have noise-related ear trauma perceive sounds, using a 3D (three-dimensional) sound setup. The results may help doctors better understand sound processing after acoustic injuries.
LyonAges 18–65 - NCT05546138Recruiting
Study for early diabetic nerve damage in people with diabetes
This trial looks for and studies early nerve problems in the feet or legs that can happen with diabetes, before nerve damage is clearly diagnosed. It may help doctors better predict who is at risk and understand early changes.
AalborgAges 18–60 - NCT05773755Recruiting
Brain stimulation surgery for treatment-resistant depression
This trial studies whether deep brain stimulation (DBS)—a surgically placed brain device—can reduce severe, long-lasting depression that hasn’t responded to many treatments. It may help people whose depression has persisted despite trying multiple antidepressant and other evidence-based therapies.
New York, New YorkAges 25–70 - NCT05981482Recruiting
Understanding vision problems after a recent stroke
This study looks at how stroke may affect the way you see and make sense of what's around you. It aims to better understand these visual challenges and may lead to better support after a stroke.
AbingdonAges 18 years+ - NCT06098482Recruiting
Testing speech understanding with a mobile app for hearing device users
This study uses a smartphone app to test how well adults who use hearing aids or cochlear implants can understand speech. It aims to see if the app is a reliable way to measure hearing performance, which could make future check-ups easier and more convenient.
Lone Tree, ColoradoAges 18 years+ - NCT06237790Recruiting
Comparing speech understanding: gene therapy vs. cochlear implant
This study compares how well people with severe hearing loss from birth understand speech after either gene therapy (which fixes a faulty gene) or a cochlear implant (a device that helps you hear). It includes healthy people with normal hearing as a comparison group, and it aims to see which treatment works better for understanding spoken language.
Beijing, Beijing MunicipalityAges 6 months+ - NCT06377215Recruiting
How well do you hear speech in noise?
This study tests how well people understand speech in noisy settings, comparing younger and older adults with normal hearing and older adults with hearing loss. It aims to improve our understanding of hearing aid benefits.
Tampa, FloridaAges 18–80 - NCT06659731Recruiting
Pain testing in children with autism
This study measures how children with autism experience pain using simple tests like warmth or pressure. It helps researchers understand sensory differences in autism.
Brindisi, BRAges 5–17 - NCT06660225Recruiting
Deep brain stimulation for severe OCD
This trial tests if deep brain stimulation (a surgical treatment that uses electrical pulses to adjust brain activity) can help people with severe obsessive-compulsive disorder (OCD) that has not improved with other treatments. It is for adults aged 22 to 75 who have had OCD symptoms for over 5 years.

Common questions
- Are there clinical trials for perception?
- Yes. Clin2 currently lists 208 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.
