What is the most likely explanation for her behavioral and physiological symptoms?   A. The alcohol increased the actions of GABA at the GABA receptor chloride channel   B. The alochol increased dopamine and serotonin activity by running the transporters backwards   C. The alcohol blocked the dopamine reuptake transporter   D. the alcohol activated serotinin autoreceptors in the brain   E. none of the above

30.  Let's consider the pups of that new rat mom. If her behavior is changed as a result of an oxytocin infusion, what effect would this likely have on the hippocampi of the pups? a. Increased production of glucocorticoid receptors, leading to worse control of the stress response b. Decreased production of glucocorticoid receptors, leading to better control of the stress response c. Decreased production of glucocorticoid receptors, leading to worse control of the stress response d. Increased production of glucocorticoid receptors, leading to better control of the stress response

Suppose you are lost in concentration while studying biology. Suddenly, the phone rings and it  startles you. A. Outline TWO physiological changes due to release of  EACH stress hormone cortisol and epinephrine.             B. What triggers the release of each of these hormones?
