  • Neural Explanations

    A) ?
  • Neurotransmitters responsible for


    • Relaying information from one neuron to the other across a synapse
  • What is serotonin?
    ?
    A) ?
  • Role of Serotonin in OCD & low levels of serotonin means?
    ?
    A) ?
    • Role of serotonin in OCD = This explanation of OCD came out due to the success of early antidepressants (Clomipramine) in relieving symptoms of OCD. Clomipramine increases the amount of serotonin available in the synapse.
  • The Orbito-frontal circuit?
    ?
    A) ?
  • In healthy people & the orbito-frontal circuit?
    ?
    A) ?
  • People with OCD & the orbito-frontal circuit?
    ?
    A) ?
  • The brain is made up of neuronal pathways (or brain circuits)
  • What is the OFC linked with?

    • The OFC is linked with thoughts, decisions making & planning
  • OFC is a ___? And consists of? located where?
    • The OFC is a neuronal pathway that connects the Orbitofrontal cortex (situated close to eyes) with other parts of the brain.
    • This neuronal pathway consists of both an excitatory pathway and an inhibitory pathway.
  • Parahippocampal Gyrus Dysfunctional & OCD
    ?
    A) ?
  • Genes associated with OCD are likely to affect the levels of key neurotransmitters as well as structures of the brain. These are NEURAL EXPLANATIONS.
  • What to most drugs for treating OCD aim to do?

    • OCD is associated with low levels of serotonin and therefore drugs work to increase levels of serotonin in the brain.
