Q

Below is a serotonin neuron, give the number and what they do

A
  1. SSRI- most common
  2. Post synaptic serotonin receptor agonist
  3. Tryphotan hydroxylase inhbitor- DOES NOT HELP WITH DEPRESSION
  4. Monoamine oxidase inhibitor
  5. Serotonin auto-receptor antagonist- decrease serotonin release normally due to negative feedback.

Anti-depressant drugs try to increase serotonin receptors in synaptic cleft
