Fear Extinction Learning: Psilocybin-Assisted Psychotherapy for Complex PTSD
Psilocybin dampens amygdalar reactivity during traumatic memory recall, enabling patients to reprocess traumatic events with reduced autonomic fear responses.
Amygdala Hyper-Reactivity in PTSD
Post-Traumatic Stress Disorder (PTSD) is characterized by hyper-responsiveness of the amygdala paired with deficient top-down inhibition from the medial prefrontal cortex during trauma cues.
Modulation of Amygdalar Threat Processing
fMRI investigations confirm that psilocybin temporarily attenuates reactivity in the right amygdala when exposed to negative emotional stimuli, creating a safe neurobiological window for trauma processing.
Enhancing Extinction Memory Consolidation
By facilitating fear extinction consolidation while enhancing prefrontal-limbic cross-talk, psilocybin allows patients to decouple traumatic memories from intense visceral panic responses.
