Ginkgolides protect primary cortical neurons from potassium cyanide-induced hypoxic injury.

abstract：:Changing direction during walking is a common task humans encounter every day. This destabilizing event requires the central nervous system (CNS) to quickly produce an appropriate response, maintain stability, and propel the body in the intended direction. Previous research has demonstrated that 'individuals with mult...
