Morphine reward in dopamine-deficient mice

Article Abstract:

Morphine was administered to dopamine-deficient mice to test the hypothesis that dopamine is an essential mediator of many behavioral responses. It is found that though dopamine is a critical component of morphine-induced locomotion and modulates pain sensitivity, it is not required for mice to learn a conditional association for morphine.

Article Abstract:

Calorie reduction, or cutting energy intake below energy expenditure helps to slow ageing, reduces mortality and increases maximum lifespan in rats, mice, fish, flies, worms and yeast. Scientists are not yet sure whether calorie restriction increases the life span, but it may help to avoid certain age-related diseases.
