This assignment explores the mechanisms of psychiatric drugs, the adaptive function and potential drawbacks of the “fight-flight-freeze” response, and the evolutionary significance of the amygdala and hippocampus in humans.

How do psychiatric drugs mimic the effects of neurotransmitters in order to treat psychological disorders?
How can the “fight-flight-freeze” response be helpful to humans in emergency situations? When may the “fight-flight-freeze” response be harmful, or non-beneficial? 
The amygdala and hippocampus are located in close physical proximity to one another in the brain. What significance or importance has this had on human evolution?
