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.

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 Results may not be published yet.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 This study
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This status has not been confirmed recently, so it may be out of date.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 planned to use high-frequency brain signals to locate important brain areas and understand conditions like epilepsy, migraine, and ADHD. It aimed to create a large database of brain activity in people aged 1 day to 69 years. However, the study was withdrawn before any volunteers were enrolled, so no results are available.

Who can take part

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

Who is studied

The study will obtain MEG/EEG data from healthy subjects, recruiting only individuals without underlying health conditions. Additionally, this study will utilize clinical MEG/EEG data from patients, which are acquired as part of standard clinical care for clinical purposes. Since women, girls, and minorities are included in the population to whom recruiting materials are directed, we anticipate that subject selection will be equitable.

Ages

1 day to 69 years

Sex

Anyone

Healthy volunteers

Accepted

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

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

Inclusion Criteria: * Healthy and cooperative. * Ages: from 1 day to 69 years (male or female). * Normal hearing and vision. * Normal hand movement. * No history of neurological or psychiatric diseases. * No family history of genetic neurological or psychiatric diseases. * No metal implants such as pacemakers, neuro-stimulators, cochlear implants, etc. Exclusion Criteria: * Taking any medications for depression, neurologic, or psychiatric conditions. * Not feeling well, having epilepsy, or other brain disorders. * Recent concussion or head injury. * Presence of metal in the body, such as dental braces, which could cause "magnetic noise". A simple, quick "magnetic noise screening" can be conducted at the MEG Center to determine eligibility. * Presence of electrical or metal implants such as pacemakers, neuro-stimulators, or orthopedic pins or plates. The research nurse will discuss all exclusions in further detail before the magnetic resonance imaging (MRI) scan. * Inability to pass the pre-experimental screening.
