Why Zebras Don't Get Ulcers

Name: Why Zebras Don't Get Ulcers
Author: Robert M. Sapolsky

Why Zebras Don't Get Ulcers is a 1994 book by Stanford University biologist Robert M. Sapolsky. The book proclaims itself as a "Guide to Stress, Stress-Related Diseases, and Coping" on the front cover of its third and most recent edition. The title derives from Sapolsky's idea that for animals such as zebras, stress is generally episodic , while for humans, stress is often chronic . Therefore, many wild animals are less susceptible than humans to chronic stress-related disorders such as ulcers, hypertension, decreased neurogenesis and increased hippocampal neuronal atrophy. However, chronic stress occurs in some social primates for individuals on the lower side of the social dominance hierarchy.

“On an incredibly simplistic level, you can think of depression as occurring when your cortex thinks an abstract thought and manages to convince the rest of the brain that this is as real as a physical stressor.”

“If I had to define a major depression in a single sentence, I would describe it as a "genetic/neurochemical disorder requiring a strong environmental trigger whose characteristic manifestation is an inability to appreciate sunsets.”
