Vascular safety of brain plasticity induction via transcranial direct currents

摘要

Experience alters the strength of neuronal connections as a fundamental feature of brain physiology. This process, termed neuroplasticity, appears crucially involved in cognitive processes such as learning, memory formation, and adaptive behavior. Neuroplasticity is increasingly implicated in not only a number of neurologic diseases, but also in restitution after brain injury. Noninvasive brain stimulation can induce and modulate neuroplasticity in humans.(1) In accordance with the functional relevance of neuroplasticity, noninvasive brain stimulation not only modulates psychological processes and behavior in healthy humans, but also reduces symptoms, and improves rehabilitation, in patients with neurologic diseases, including stroke.(2-4
