Study Details

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.

Interventions and Outcome Measures

Arms

experimental: Healthy Participants (Study 1)

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.

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

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.

experimental: Depressed Participants - Cognitive Behavioral Therapy Only (Study 4)

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.

Interventions

Single-Pulse Transcranial Magnetic Stimulation

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

EEG-Synchronized Repetitive Transcranial Magnetic Stimulation (rTMS)

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.

Cognitive Behavioral Therapy (CBT)

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.

Cognitive Flexibility and Emotion Regulation Tasks

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.

Primary outcome measure

  • Change in Hamilton Depression Rating Scale (HAM-D) Score [ Time Frame: Baseline to Day 7 ]
  • Change in Patient Health Questionnaire-9 (PHQ-9) Score [ Time Frame: Baseline to Day 7 ]
  • Change in Suicide Cognitions (Brief Suicide Cognitions Scale [B-SCS]) [ Time Frame: Baseline to Day 7 ]
