Causal Role of Delta-beta Coupling for Goal-directed Behavior in Anhedonic Depression

NCT06132581 · Status: RECRUITING · Phase: NA · Type: INTERVENTIONAL · Enrollment: 72

No results posted yet for this study

Summary

Anhedonia, the inability to seek-out and experience pleasure, is a common symptom in depression that predicts treatment-resistance and is sometimes exacerbated by first-line antidepressants. In our previous research, we found that anhedonia decreases goal-directed behavior and its related neural activity. In this study, we will investigate target engagement from five-consecutive days of stimulation for participants that are within a unipolar major depressive episode and also have high symptoms of anhedonia.

Conditions

Interventions

DEVICE

Delta-beta tACS via the Neurocare Direct Current Stimulator Multi-Channel 4

Stimulation will be delivered via the Neurocare Direct Current Stimulator Multi-Channel 4, an investigational electrical non-invasive brain stimulation device that is being used for foundational neuroscience and translational research. The electrical waveform for stimulation was designed to mimic delta-beta coupling in the brain.

DEVICE

Theta-gamma tACS via the Neurocare Direct Current Stimulator Multi-Channel 4

Stimulation will be delivered via the Neurocare Direct Current Stimulator Multi-Channel 4, an investigational electrical non-invasive brain stimulation device that is being used for foundational neuroscience and translational research. The electrical waveform for stimulation was designed to mimic theta-gamma coupling in the brain and is used as an active comparator.

DEVICE

Sham tACS via the Neurocare Direct Current Stimulator Multi-Channel 4

Stimulation will be delivered via the Neurocare Direct Current Stimulator Multi-Channel 4, an investigational electrical non-invasive brain stimulation device that is being used for foundational neuroscience and translational research. The electrical waveform is randomly selected to be the theta-gamma or delta-beta waveform, but the stimulation is delivered for only a brief period of time of approximately 30 seconds, which is not sufficient to produce a meaningful dose to the brain. This placebo, or sham, stimulation is designed to mimic the sensation of receiving stimulation.
