“Rats and mice are often instrumental in testing new drug treatments before they reach the clinical use phase. To create the appropriate conditions to test a drug for depression, though, researchers need to induce a model of depression in the test subject.”
“In order to create a workable model of a human mental disorder like depression, anxiety or schizophrenia, rats are often genetically manipulated or have their nerve system surgically altered. Sometimes they are forced to swim for long periods of time. Now, researchers at Waseda University in Tokyo have created a new method: Let a robotic rat terrorize the rats into depression.”
