A modern understanding of how cerebral cortical lesions develop after acute brain injury is
based on Aristides Leão's historic discoveries of spreading depression and asphyxial/anoxic …

Blood flow in the brain is regulated by neurons and astrocytes. Knowledge of how these
cells control blood flow is crucial for understanding how neural computation is powered, for …

Spreading depolarizations (SD) are waves of abrupt, near-complete breakdown of neuronal
transmembrane ion gradients, are the largest possible pathophysiologic disruption of viable …

The term spreading depolarization describes a wave in the gray matter of the central
nervous system characterized by swelling of neurons, distortion of dendritic spines, a large …

First introduced in the 1980s, laser speckle contrast imaging is a powerful tool for full-field
imaging of blood flow. Recently laser speckle contrast imaging has gained increased …
