NCT05977439

Brief Summary

In this research study, investigators examine how brain activity changes during tests of emotional processing, attention, and memory using multimodal neuroimaging methods including electroencephalography (EEG), functional magnetic resonance imaging (fMRI), and functional near-infrared spectroscopy (fNIRS). Transcranial magnetic stimulation (TMS) is used to probe and modulate brain networks related to cognitive flexibility and emotion regulation. The study includes multiple related sub-studies involving healthy participants and participants with depression. Some study components focus on mechanistic modeling using non-therapeutic neurostimulation in healthy participants, while other components include interventional approaches such as individualized EEG-synchronized repetitive TMS (rTMS), cognitive tasks, and brief cognitive behavioral therapy (CBT) in participants with depression. Certain study components also evaluate CBT alone without TMS to assess behavioral intervention effects.

Outcome Measures

Primary Outcomes (3)

  • Change in Hamilton Depression Rating Scale (HAM-D) Score

    hange in clinician-rated depression severity measured using the Hamilton Depression Rating Scale (HAM-D). Scores range from 0 to 52; higher scores indicate more severe depression.

    Baseline to Day 7

  • Change in Patient Health Questionnaire-9 (PHQ-9) Score

    Change in self-reported depression severity measured using the Patient Health Questionnaire-9 (PHQ-9). Scores range from 0 to 27; higher scores indicate more severe depression.

    Baseline to Day 7

  • Change in Suicide Cognitions (Brief Suicide Cognitions Scale [B-SCS])

    Change in suicide-related cognitions measured using the Brief Suicide Cognitions Scale (B-SCS). Higher scores indicate greater severity of maladaptive suicide-related cognitions.

    Baseline to Day 7

Secondary Outcomes (7)

  • Change in Reaction Time During Cognitive Flexibility Tasks

    Baseline to Day 7

  • Change in Accuracy on Cognitive Flexibility Tasks

    Baseline to Day 7

  • Change in Generalized Anxiety Disorder-7 (GAD-7) Score

    Baseline to Day 7

  • Change in EEG Alpha Phase Synchronization

    Baseline to Day 7

  • Change in Functional Connectivity Strength (fMRI)

    Baseline to Day 7

  • +2 more secondary outcomes

Study Arms (3)

Healthy Participants (Study 1)

EXPERIMENTAL

Healthy adult participants with no history of psychiatric or neurological illness who undergo mechanistic and modeling procedures, including multimodal neuroimaging, behavioral cognitive tasks, and nontherapeutic neurostimulation, to characterize brain networks underlying cognitive flexibility and emotion regulation.

Device: Single-Pulse Transcranial Magnetic StimulationBehavioral: Cognitive Flexibility and Emotion Regulation Tasks

Depressed Participants - EEG-Synchronized rTMS (Studies 2 and 3)

EXPERIMENTAL

Participants with major depressive disorder who receive individualized, EEG-synchronized repetitive transcranial magnetic stimulation (rTMS), delivered alone or in combination with cognitive tasks and/or brief cognitive behavioral therapy (CBT), to modulate neural networks underlying cognitive flexibility and emotion regulation.

Device: Single-Pulse Transcranial Magnetic StimulationDevice: EEG-Synchronized Repetitive Transcranial Magnetic Stimulation (rTMS)Behavioral: Cognitive Behavioral Therapy (CBT)Behavioral: Cognitive Flexibility and Emotion Regulation Tasks

Depressed Participants - Cognitive Behavioral Therapy Only (Study 4)

EXPERIMENTAL

Participants with major depressive disorder who receive a course of cognitive behavioral therapy (CBT) along with MRI and behavioral assessments, without transcranial magnetic stimulation or EEG-based neurostimulation. This group allows evaluation of behavioral intervention effects independent of neurostimulation.

Behavioral: Cognitive Behavioral Therapy (CBT)Behavioral: Cognitive Flexibility and Emotion Regulation Tasks

Interventions

Single-pulse transcranial magnetic stimulation delivered during EEG or neuroimaging sessions for non-therapeutic mapping of cortical excitability and functional connectivity.

Depressed Participants - EEG-Synchronized rTMS (Studies 2 and 3)Healthy Participants (Study 1)

Repetitive transcranial magnetic stimulation delivered using individualized, EEG-derived stimulation parameters designed to synchronize stimulation timing with participants' alpha oscillatory phase. This closed-loop approach is intended to modulate neural networks underlying cognitive flexibility and emotion regulation. Stimulation may be delivered in accelerated sessions across multiple days.

Depressed Participants - EEG-Synchronized rTMS (Studies 2 and 3)

A structured, brief cognitive behavioral therapy program targeting depression and related symptoms, including cognitive restructuring, emotion regulation, and coping skill development, delivered in an accelerated format during the study period.

Depressed Participants - Cognitive Behavioral Therapy Only (Study 4)Depressed Participants - EEG-Synchronized rTMS (Studies 2 and 3)

Behavioral tasks designed to engage and assess cognitive flexibility and emotion regulation processes, performed during or adjacent to neurostimulation sessions or as part of study assessments.
