ReviewBehavioral and Cognitive Consequences of Spreading Depolarizations: A Translational Scoping Review.
Spreading depolarizations (SDs) are self-propagating waves of mass depolarization that cause silencing of brain activity and have the potential to impact brain function and behavior. In the eight decades following their initial discovery in 1944, numerous publications have studied the cellular and molecular underpinning of SDs, but fewer have focused on the impact of SDs on behavior and cognition. ⋯ This study summarizes the known behavioral and cognitive consequences of SDs based on historical studies on awake animals, recent experimental paradigms, and modern clinical examples. This scoping review showcases our current understanding of the impact of SDs on cognition and behavior and highlights the need for continued research on the consequences of SDs.
