Fear of predators causes PTSD-like changes in brains of wild animals | Science Daily

Fear can be measured in the brain and fearful life-threatening events can leave quantifiable long-lasting traces in the neural circuitry of the brain with enduring effects on behaviour, as shown most clearly in post-traumatic stress disorder (PTSD).

A new study by Western University demonstrates that the fear predators inspire can leave long-lasting traces in the neural circuitry of wild animals and induce enduringly fearful behaviour, comparable to effects seen in PTSD research.

The findings of this study, led by Western University’s Liana Zanette, Scott MacDougall-Shackleton and Michael Clinchy, were published today in Scientific Reports — Nature.
