Women More Sensitive to Cocaine
Presented with a choice between cocaine and food, female rats choose the drug while male rats go for the grub, a new study finds. The result may help clarify differences in addiction between men and women, scientists reported November 14 at the annual Society for Neuroscience meeting.
Kerry Kerstetter of the University of California, Santa Barbara and colleagues trained rats to press one lever to receive food or a separate lever to receive cocaine. Later, the rats were presented with the food lever and the cocaine lever at the same time.
