Thrill-Seeking Female Rats Work Harder for Next Drug Fix

RoseTracker| While acknowledging that certain personality types are perhaps more predisposed towards drug addiction, Dr Jennifer Cummings, a researcher from the Molecular and Behavioral Neuroscience Institute, University of Michigan, believes that women are more likely to succumb to drug abuse than men.

Rats of both sexes, bred to have an elevated stress response and increased impulsiveness are more likely to respond to the reward of cocaine.

Female rats given low doses of cocaine were more determined than male rats to get their next fix. They figured out faster how to self-administer the drug and worked harder and longer to get more of it.

At higher doses, the gender-based behavior was less apparent but apparently still differentiated. via Science Daily
