One way to do this is by injecting drugs directly into the animal’s body. These drugs are injected into the animal’s bloodstream, where they then travel through the bloodstream to their brain. Once in the brain, the drug molecules travel along nerve fibers, stimulating cells to produce proteins and chemicals needed for cell reproduction, growth, and survival.
Drugs can also be injected directly into the animal’s muscle. When a drug enters a muscle, it travels into the muscle fiber, where it then travels along the muscle fiber to the brain. Once in the brain, the drug travels along the same pathway that the protein molecules traveled. Because of this, scientists can measure both drug concentrations and drug effects simultaneously. – http://www.prisysbiotech.com/
