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 This study
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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 uses low-intensity focused ultrasound (LIFU) to gently stimulate the brain while recording responses with implanted electrodes. Researchers aim to map how different brain regions communicate in real time. About 30 adults with epilepsy or other conditions who already have brain electrodes will participate. The goal is to understand brain connectivity, not to treat any disease.

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 30 people

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

Started

Mar 2026

Expected to finish

Mar 2031

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

21 to 75 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.

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

Inclusion Criteria: 1. Patients who received (or are scheduled to receive) intracranial electrode implantation surgery as part of standard clinical care or as participation in an ongoing research study for the treatment of epilepsy and/or neuropsychiatric conditions at Pennsylvania Hospital (PAH) or Hospital of the University of Pennsylvania (HUP). 2. Adult patients, 21 to 75 years of age 3. Patients considered to be in a stable medical condition, in the opinion of the PI 4. Patients who are able to demonstrate comprehension of instructions in the English language, in the opinion of the PI 5. Patients who are able to provide informed consent and fully comply with all study requirements, in the opinion of the PI Exclusion Criteria: 1. Patients with chronic alcohol abuse history 2. Patients with additional implanted devices, such as an aneurysm clip, large cranial plates or mesh that may intersect with ultrasonic beam path 3. Open scalp wounds, infection or dermatologic condition that preclude safe placement of ultrasound transducer 4. Intracranial mass lesion with significant mass effect near intended beam path 5. Patients who are pregnant at the time of screening or patients who get pregnant during the course of the study 6. Patients with any past or present medical condition, disease, disorder, or injury that, in the opinion of the PI, may reduce or hinder the participant's ability to fully comply with all study requirements or may impact, compromise, or affect the integrity of the data or the results of the study
