The defense by University of Utah assistant professor of bioengineering Bradley Greger of his invasive brain experiments on monkeys in response to criticism from the People for the Ethical Treatment of Animals was flabbergasting ("PETA spy infiltrates U. of U. labs," Nov. 12).

Greger drills holes into monkeys' heads, places microelectrodes on their brains and deprives them of water to coerce them to "cooperate" in his experiments. They spend their lives in tiny cages and are driven insane by the traumatic laboratory conditions. But Greger defends all of this by boasting that the monkeys used in his experiments have plenty of toys and a Netflix account.

Greger is a bioengineer. He should stick to that and leave the monkeys alone.
