How lifetime stress drives abnormal behaviors in lab monkeys
Why it matters: Understanding lifetime stress in lab animals could revolutionize research ethics and improve animal welfare.
- Abnormal repetitive behaviors (ARBs) in lab monkeys, like pacing and hair-plucking, are common.
- Conventional thinking previously linked ARBs to recent stresses or current housing conditions.
- A new study in Biology Letters proposes that lifetime stress, rather than just recent events, drives these abnormal behaviors, offering a more nuanced understanding of their origins.
A new study challenges the long-held belief that abnormal repetitive behaviors (ARBs) in lab monkeys are solely due to recent stress or current housing, suggesting instead that lifetime stress accumulation is a primary driver. This research, published in Biology Letters, indicates a more complex and chronic origin for these behaviors, which could significantly alter how animal welfare and research protocols are approached.
