About this study
Official title: Relationship Between Brain Oscillations and Neural States
The study aims to investigate, through the use of electroencephalography (EEG), instantaneous brain states, namely rapid oscillations of the brain's electrical activity, and their relationship with behavior and brain functions. The study will focus on three main objectives: (1) establishing a relationship between brain oscillations and behavior; (2) establishing a relationship between brain oscillations and brain functions, in terms of neural responsiveness; and (3) identifying the different phases of brain oscillations and investigating any related modulations of behavior and brain functions.
PHAROS will combine EEG with transcranial magnetic stimulation (TMS) to investigate and modulate brain states non-invasively.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Behavioral TreatmentOther
Imagining an abduction movement of the right index finger
Behavioral TreatmentOther
Imagining the right index finger remaining still, which will serve as the control condition
| Study group | Role | What they receive |
|---|---|---|
| Real motion | Experimental | Participants will be asked to perform a possible motor imagery task: imagining an abduction movement of the right index finger. Each session will consist of three blocks, counterbalanced across participants. During these blocks, single TMS pulses will be delivered at different phases of the EEG oscillation: positive peak, negative peak, and random phase, the latter serving as the control condition. Receives: Other: Behavioral Treatment |
| No motion | Sham comparator | Participants will be asked to perform a possible motor imagery task: imagining the right index finger remaining still, which will serve as the control condition. Each session will consist of three blocks, counterbalanced across participants.

What is being measured
The primary outcome is the main question the study is designed to answer.
Motor-evoked potential
Motor-evoked potentials (MEPs) will be recorded from the right index-finger abductor muscle following single-pulse TMS delivered over the primary motor cortex. MEPs will be used as an index of corticospinal excitability. The main outcome measure will be the peak-to-peak MEP amplitude, calculated as the difference between the maximum and minimum EMG signal within the post-stimulation time window.
Measured: Baseline

TMS-evoked potential
TMS-evoked potentials (TEPs) will be recorded using EEG following single-pulse TMS. TEPs will be used as an index of cortical responsiveness to stimulation. The main outcome measures will be the amplitude and latency of the main TEP components within predefined post-stimulation time windows.

The study will focus on three main objectives: (1) establishing a relationship between brain oscillations and behavior; (2) establishing a relationship between brain oscillations and brain functions, in terms of neural responsiveness; and (3) identifying the different phases of brain oscillations and investigating any related modulations of behavior and brain functions.

What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. 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?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
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?
Motor-evoked potential (time frame: Baseline). The study lists 4 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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 9 Jun 2026.
