Science fiction writer Tim Maughan reports on the real science of making animals smarter:
In 2011, a research team led by Sam Deadwyler of Wake Forest University in Winston-Salem, North Carolina, used five rhesus monkeys to study the factors that lead people with diseases like Alzheimer’s to lose control of their thought processes. The researchers trained the monkeys in an intelligence task that involved learning and identifying images and symbols. They were then given doses of cocaine in order to dull their intelligence and made to repeat the test, with predictably less impressive results.
What happened in the next stage of the research was remarkable. The same monkeys were fitted with neural prosthetics – brain implants designed to monitor and correct the functions of the neurons disabled by the cocaine. These implants successfully restored normal brain function to the monkeys when they were drugged – but crucially, if they were activated before the monkeys had been drugged, they improved the primates’ performance beyond their original test results. The aim of the experiments was to see whether neural prosthetics could theoretically be used to restore decision-making in humans who have suffered trauma or diseases such as Alzheimer’s – but as far as these specific tests were concerned at least, the brain prosthetics appeared to make the monkeys smarter.
While the obvious answer to that question is “hell no,” Tim points out that the medical research research motivations may make smarter animals an inevitability. He dives deeper into the ethical questions in the article.
