How are atypical antipsychotics different from the older generation of antipsychotics (i.e. chlorpromazine)? 8.

What structural changes occur in the brains of patients with anxiety and panic disorders? 18. What is the mechanism of action of the anxiolytic drugs called benzodiazepines? Why do they reduce anxiety? 19. Does post-traumatic stress disorder have a genetic component? What brain region and neurotransmitter receptor may be involved in PTSD? 20. What are some of the symptoms of obsessive-compulsive disorder? 21. Which brain regions are implicated in OCD, and which neurotransmitter system is targeted by drugs that reduce the symptoms of OCD? 22. What is a lobotomy and why was it performed? 23.
