what this means

• In a "normal brain", the worry circuit (the OFC, basal ganglia and thalamus) functions efficiently, filtering out unnecessary thoughts and allowing the person to continue.
• In an "OCD brain", the worry circuit fail to regulate obsessive thoughts, causing a repetitive cycle of anxiety and compulsions.
• • basal ganglia: Coordinates movement. Head injuries in this area can trigger OCD-like symptoms.
• • Orbitofrontal cortex: Converts sensory info into actions.
  • PET scans show increased activity in OCD patients, leading to compulsive behaviors.
