Document Summary
For those chapters that there will be questions with a list of symptoms and you have to give a diagnosis. The wrong answers there will be a flaw that makes the rest a wrong diagnosis, so there"s only going to be one correct answer. Looked at specific cause for anxiety with 5-ht. they looked at receptors on dendrites. What they did was they genetically engineered mice without those receptors, and those mice showed higher levels of anxiety. Wanted to see if you could have a sensitive period and also if a specific area of the brain where you lack it leads to anxiety (looked for spatial and temporal issue) Suppression of those receptors in adulthood = no effect, so critical period was not in adulthood. They suppressed it in the first four week, and after that they allowed the gene to be expressed, so everything worked the way it was supposed.
