Characterization of a semi-rapid method for assessing delay discounting in rodents

► Delay discounting is a key component of addiction and many behavioral disorders. ► Rodent modeling of this task is necessary for mechanistic understanding. ► We have developed a task more rapid than most rodent versions of delay discounting. ► This version of the DD task is sensitive to reward magnitude and chronic cocaine. ► Rats adjust to increasing delays within-session and establish stable performance.
