One particularly egregious example is a decades-long series of highly invasive monkey experiments performed at universities across the country to study neural control of visual tracking. Luckless monkeys have coils implanted in both eyes, multiple craniotomies for electrode placements in their brains and head immobilization surgeries in which screws, bolts and plates are directly attached to their skulls. This is followed by water deprivation to produce a "work ethic" so they will visually track moving objects.
... before concluding
Because such monkey torture will not lead to improved human health, you don't need to be an animal rights advocate to wonder if an ethical cost-benefit analysis might conclude the ends just don't justify the means, especially since rapid advances in sophisticated high-resolution neuroimaging on humans will very soon obviate the need for such invasive techniques.... Most animal experiments on monkeys, dogs, cats and other animals are not related to human benefit, and describing such research as "humane" requires an Orwellian-newspeak definition of the word. "Humane" means to treat with kindness, consideration or mercy, and as long as words have meanings that cannot be twisted Humpty Dumpty-like into whatever we want them to mean, animal experimentation is not and can never be humane.
Based on my readings, many animal researchers simply believe in experimentation for the sake of experimentation. They enjoy the scientific process, and if animals are tortured in the process, so be it, as long as it's in the interest of the great god Science. Whether or not there is any actual relevance to the research seems to be besides the point.
