Brief Summary:
This project seeks to identify causal neural mechanisms underlying unwanted, repetitive behaviors (compulsions). Using non-invasive brain stimulation coupled with practice in a computer task, we will modulate activity in a target brain region and measure effects on compulsive behaviors and related measures. This work could ultimately lead to the ability to treat compulsions more effectively by targeting the regions of the brain that can help or hinder attempts to overcome compulsions.

Primary Outcome Measures :
  1. Brain activation in target region [ Time Frame: 10-60min post-intervention ]
    Mean Cerebral Blood Flow (CBF) in orbitofrontal cortex collected via functional Magnetic Resonance Imaging (fMRI)

  2. Effort to resist compulsive behaviors in response to laboratory triggers [ Time Frame: 60min post-intervention ]
    Custom-made laboratory assessment of ability to override compulsive behaviors in response to idiographic triggers: self-reported effort needed to resist (0-100 scale)

  3. Duration of compulsive behaviors in response to laboratory triggers [ Time Frame: 60min post-intervention ]
    Custom-made laboratory assessment of ability to override compulsive behaviors in response to idiographic triggers: duration of compulsive behavior performance (% of total time allotted)

  4. Intensity of urges to perform compulsive behaviors in response to laboratory triggers [ Time Frame: 60min post-intervention ]
    Custom-made laboratory assessment of ability to override compulsive behaviors in response to idiographic triggers: self-reported urge intensity (0-100 scale)


Secondary Outcome Measures :
  1. Goal-directed cognition [ Time Frame: 90min-1 week ]
    Neuropsychological test of flexible goal-directed cognition (two-step task): switch score (higher score=better performance)

  2. Yale-Brown Obsessive Compulsive Scale (Y-BOCS) [ Time Frame: 1 week ]
    Clinician-administered measurement of obsessions and compulsions (range: 0-40; higher score=worse outcome)

  3. WHO Disability Assessment Scale 2.0 [ Time Frame: 1 week ]
    Self-report measure of general functioning and disability (0-100; higher score=worse outcome)

  4. Obsessive Compulsive Inventory-Revised (OCI-R) [ Time Frame: 1 week ]
    Self-report measure of obsessions and compulsions (0-72; higher score=worse outcome)

  5. Effort to resist compulsive behaviors in response to laboratory triggers [ Time Frame: 1 week ]
    Custom-made laboratory assessment of ability to override compulsive behaviors in response to idiographic triggers: self-reported effort needed to resist (0-100 scale)

  6. Duration of compulsive behaviors in response to laboratory triggers [ Time Frame: 1 week ]
    Custom-made laboratory assessment of ability to override compulsive behaviors in response to idiographic triggers: duration of compulsive behavior performance (% of total time allotted)

  7. Intensity of urges to perform compulsive behaviors in response to laboratory triggers [ Time Frame: 1 week ]
    Custom-made laboratory assessment of ability to override compulsive behaviors in response to idiographic triggers: self-reported urge intensity (0-100 scale)

  8. Brain activation in target region [ Time Frame: 1 week ]
    Mean Cerebral Blood Flow (CBF) in orbitofrontal cortex collected via functional Magnetic Resonance Imaging (fMRI)
