    • What is the neural explanation for OCD?
      -OCD is caused by abnormal levels of neurotransmitters
      -the genes associated with OCD are likely to affect the levels of key neurotransmitters (dopamine and serotonin), as well as key structures of the brain
    • What is the serotonin explanation for OCD?
      -OCD is caused by low levels of serotonin
      -if a person has low levels of serotonin, normal transmission of mood-relevant information does not take place, so mood (and other mental processes) are affected
    • The frontal lobes are responsible for decision making and logic. The lateral of the frontal lobes, when functioning abnormally, may be associated with impaired decision making.
    • Evaluate the neural explanation for OCD.?
      Strengths: SSRI's are effective at reducing OCD symptoms. which suggests serotonin may be involved in OCD
      Limitations: low levels of serotonin and low activity in the frontal lobes are neural correlates of OCD
