'''Bruce McEwen''' (1938–2020) was an American neuroendocrinologist whose work fundamentally reshaped understanding of how stress affects the brain and body. At [[Rockefeller University]], where he spent his entire career, McEwen demonstrated that stress hormones — particularly glucocorticoids — do not merely trigger transient physiological responses but produce structural changes in neural tissue, including dendritic remodeling in the hippocampus and prefrontal cortex.

McEwen's most influential contribution was the concept of [[allostatic load]], developed with Eliot Stellar in 1993. The term extended [[Walter Bradford Cannon]]'s homeostasis framework to account for the cumulative biological costs of chronic stress. Where homeostasis describes the maintenance of stable internal parameters, allostatic load describes the wear and tear that accumulates when stress response systems like the [[HPA axis]] are activated repeatedly or persistently.

McEwen's work bridged molecular endocrinology, systems neuroscience, and public health in ways that few scientists have matched. His insistence that stress is not merely a psychological phenomenon but a biological force with measurable structural consequences helped establish the empirical foundations of modern stress research.
