Noradrenergic modulation of stress induced catecholamine release: Opposing influence of FG7142 and yohimbine.

Life stress modulates decision making, particularly in the face of risk, in some cases prompting vulnerable populations to make suboptimal, life-altering choices. In the brain, stress is known to alter the extracellular release of catecholamines in structures such as basolateral amygdala (BLA) and nucleus accumbens (NAc), but the relationship between catecholamines and decision-making behavior under stress has not been systemically explored. We developed an operant touchscreen decision-making task for rats comprising elements of loss aversion and risk seeking behavior.
