What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
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
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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 looks at how the brain's arousal systems work when we see, hear, or feel things. Researchers will use brain scans, eye tracking, and electrical recordings in healthy volunteers and epilepsy patients. The goal is to understand shared brain pathways that help us stay alert and aware.

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 research could improve understanding of how the brain processes sensory information, potentially aiding future treatments for epilepsy or other neurological conditions.
What could go wrong
This is an early-stage observational study, not a treatment trial. Results may not directly lead to new therapies, and findings might not apply to all people.

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

About 202 people

The number the study aims to enrol. It can still change while the study runs.

Started

Oct 2025

Expected to finish

Dec 2030

An estimate. End dates often move.

Lead sponsor

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

13 years and older

Sex

Anyone

Healthy volunteers

Not accepted

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

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

A. The following are the inclusion/exclusion criteria for healthy participants age 18 years and up (Aim 1 and 2): Inclusion: (1) normal vision with or without the use of corrective lenses; (2) normal hearing not needing an assistive hearing device. Exclusion: (1) past history of diagnosis of a psychiatric or neurologic disease; (2) current psychiatric or neurologic disease; (3) requires hard contact lenses or glasses to maintain normal vision (prevents accurate pupil and eye gaze measurements); (4) pregnant or nonremovable ferrous metal objects inside or on the body (prevents MRI). B. The following are the inclusion/exclusion criteria for epilepsy patients with thalamic electrodes age 13 years and up (Aim 3A): Inclusion: (1) normal vision with or without the use of corrective lenses Exclusion: (1) severe vision impairment even with correction preventing ability to see stimuli (prevents accurate pupil and eye gaze measurements); (2) unable to perform the perception task due to cognitive impairment. All participants must be capable of consenting for themselves. C. The following are the inclusion/exclusion criteria for epilepsy patients with thalamic electrodes age 18 year and up (Aim 3B): Inclusion: (1) normal vision with or without the use of corrective lenses; (2) A female subject must have a negative pregnancy test and if sexually active, must be using a reliable form of birth control for the duration of the trial, be surgically sterile, or be at least two years post-menopausal. Exclusion: (1) severe vision impairment even with correction preventing ability to see stimuli (prevents accurate pupil and eye gaze measurements); (2) unable to perform the perception task due to cognitive impairment. All participants must be capable of consenting for themselves; (3) Pregnancy.
