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 Results may not be published yet.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

Summary

This early study is testing whether mild electrical or ultrasound stimulation on the skin can change brain activity in healthy adults. Researchers will measure brain waves using a special EEG cap during active and fake (sham) stimulation. The goal is to find reliable markers of brain response, which could help guide future therapies.

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 40 people

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

Started

Jun 2026

Expected to finish

Feb 2028

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

18 to 65 years

Sex

Anyone

Healthy volunteers

Accepted

You do not need to have the condition being studied to take part.

Exclusion Criteria: * History of neurological disorders (e.g., epilepsy, migraines) or psychiatric conditions requiring medication. * Active implanted medical devices (e.g., pacemakers, cochlear implants) or metal in the neck/forearm that could interfere with stimulation or recordings. * Skin conditions or open wounds at stimulation sites (cervical neck, forearm). * Women who are pregnant or breastfeeding. * Current use of medications affecting autonomic or cortical function (e.g., beta-blockers, sedatives). * Inability to sit still for recordings or understand instructions (e.g., due to severe vision/hearing impairment).
