About this study

Official title: Mapping Transcrnial Magnetic Stimulation (TMS) Responses Within the Brain Using Intracranial Electrophysiological Monitoring Recordings

The current study presents a unique opportunity to measure the direct effects of transcranial magnetic stimulation (TMS) by using intracranial electrodes to record neural activity in deep brain regions when TMS single pulses are delivered. If TMS can evoke downstream responses in neural networks of the human brain, it can be a feasible way to study circuit engagement and connectivity.

Conditions: EEG, TMS
Being tested: Single Pulse TMS

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

Single Pulse TMSDevice
single pulse TMS will be administered when participants have intracranial electrodes implanted to measure neuronal activity.

Study groups in NCT07518745
Study group	Role	What they receive
TMS	Experimental	The study visit consists of a TMS single-pulse session when intracranial electrodes are implanted to record neural activity during the TMS session. Receives: Device: Single Pulse TMS

What is being measured

The primary outcome is the main question the study is designed to answer.

Primary Endpoint #1 Brain Activity and Connectivity
Observation of effects in brain activity and connectivity within and across regions of interest before and after TMS, as measured by intracranial EEG. The evoked response magnitude from the EEG at all features of the time-frequency analysis are used.
Measured: From enrollment to the end of study participation at 5 weeks
Primary Endpoint #2: Safety Feasibility
Safety, as defined by the number of adverse events (AE)
Measured: From enrollment to end of study participation at 5 weeks.

Questions about this trial

What is this clinical trial studying?

A study testing Single Pulse TMS in people with EEG and TMS, run by University of Pennsylvania at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: enrolling by invitation, as of the sponsor's last update on 1 May 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Primary Endpoint #1 Brain Activity and Connectivity (time frame: From enrollment to the end of study participation at 5 weeks). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT07518745, which also lists 15 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 1 May 2026.
