Abstract
Quantitative electroencephalographic studies have been done on the effects of morphine and nalorphine on brain electrogenesis in rabbits.
It has been found that the curves relating log-dose/effect are not the same for the effects of these drugs.
The blocking action of nalorphine on morphine revealed an apparent all-or-none threshold of action and a proportionally longer duration of action for small doses of nalorphine than for large doses.
