Who can join

Ages 18 to 65 · All sexes

Inclusion Criteria:

* Ability to provide informed consent
* Willingness to participate in study
* No history of musculoskeletal impairment or neurological disease
* Clinical diagnosis of PTSD for individuals in the PTSD group.

Exclusion Criteria:

* Any participant outside the age range
* Participants that show signs of dementia (score \< 20 on the Montreal Cognitive Assessment)
* Participants that have a history of major head trauma, a neurodegenerative disorder, or recent (\<6 months) substance abuse;
* Participants that had a recent history of Central Nervous System (CNS) active drugs that may influence cortical excitability or learning; or
* Participants that report contraindications to TMS or MRI - if participating in the TMS/MRI experiments
* Current psychoactive medication usage
* Current symptoms of psychosis or bipolar disorder (as indicated by study staff through a clinical interview as part of that study).
* The study will exclude adults unable to consent, individuals who are not yet adults, pregnant women and prisoners on scientific grounds and to minimize risk.

About the study

This project represents a unique collaborative opportunity to pursue the essential proof-of-principle demonstration that non-invasive interference of sensory cortical memory consolidation shortly after an emotional experience can attenuate the cued fear response and potentially reduce the risk of developing post-traumatic stress disorder (PTSD). If successful, the study results would anchor a potential advance in the treatment of patients after a traumatic event and seed future animal and clinical studies of emotional sensory cortical memory consolidation to reduce the prevalence and negative sequelae of PTSD.
