      • Genetics
  • Neurotransmitters
    • Serotonin  = important neurotransmitter for communication between neurons
  • High levels in the orbital frontal cortex = OCD
    • Brain Abnormalities
    • Can be measured using PET scans
      • Unethical - Injecting radioactive glucose into the bloodstream
    • Left frontal cortex
      • High levels in the orbital frontal cortex = OCD
      • Low levels of Serotonin = OCD
        • Neurotransmitters
          • Serotonin  = important neurotransmitter for communication between neurons
        • Too many neurotransmitters being passed onto the next neruon
          • Lots of Action Potential passed on
      • Studies?
        • Twin studies
      • Adoption studies
        • Studies?
          • Twin studies
      • High level of concordance = OCD is Hereditary
        • Some biological parents can't be found/ are willing to take part
          • Adoption studies
          • The child might not know they're adopted - Unethical
            • Twins share the same environment, therefore there is already a high level of concordance
              • Treatment?
                • Anti-depressent Drugs
                  • SSRI (Selective Serotonin Reuptake Inhibiters) - Prozac
              • Not sure whether this is the Cause or Effect of OCD
                • Area where information is converted from the senses into thoughts
                  • Behavior could be learnt through others or their environment - Ignores environmental factors
                    • Very Scientific
