What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed This study
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study investigates how sleep improves visual learning by scanning the brains of 10 healthy volunteers aged 18-30. Participants will undergo visual training and then have their brain activity measured with MRI and sleep monitors. The goal is to understand what happens in the brain during sleep that helps us learn better.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

What this could lead to
If successful, this study could reveal how the brain processes visual information during sleep, potentially informing future learning or rehabilitation techniques.
What could go wrong
This is a very small, early-stage study with only 10 participants. It aims to understand basic mechanisms, not to test a treatment, so direct benefits are unlikely.

This is an AI summary of the original study and may miss details. Read our disclaimer.

Study facts

What this study's own registry entry says, in plain language.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

12 people

The number who actually took part.

Started

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Ages

18 to 30 years

Sex

Anyone

Healthy volunteers

Not accepted

This study is not open to healthy volunteers. The entry requirements below say who it is open to.

Inclusion Criteria: * 18 - 30 years old * Normal or corrected to normal visual acuity Exclusion Criteria: * Self-report of visual and eye disorders (cataracts, age-related macular degeneration, diabetic retinopathy, glaucoma) * Drug use (psychoactive drugs, neuroleptic medications, prescription medications that might affect cognitive and motor performance) * History of sleep disorders (sleep apnea, insomnia) * Failure to meet the criteria on the visual acuity test * Magnetically or mechanically activated implants (such as cardiac pacemakers) * Clips on blood vessels in the brain * Use of any type of intrauterine devices * Use of dentures * Pregnancy
