过去十年积累的大量数据表明,中风后成人大脑能够进行实质性的结构和功能重组。虽然已知一些有限的恢复是自发发生的,特别是在中风后的第一个月内,但目前人们非常乐观地认为,基于神经可塑性机制调节的新干预措施将在更多的中风幸存者中提供更大的功能益处。为了将这一信息放在当前关于大脑可塑性的研究背景下,本文概述了自发恢复发生的基本理论,并介绍了解释中风后行为经验对神经可塑性影响的重要原理。读者将能够:(A)解释解释局灶性脑损伤后自发恢复的三个经典理论;(B)解释损伤后康复治疗对运动皮质功能组织的神经生理学影响;(C)读者将能够描述影响中风后行为体验对神经可塑性影响的一些变量;以及(D)读者将能够解释目前基于实验室的一些方法,这些方法可能很快就会转化为人类应用。
Substantial data have accumulated over the past decade indicating that the adult brain is capable of substantial structural and functional reorganization after stroke. While some limited recovery is known to occur spontaneously, especially within the first month post-stroke, there is currently significant optimism that new interventions based on the modulation of neuroplasticity mechanisms will provide greater functional benefits in a larger population of stroke survivors. To place this information in the context of current thinking about brain plasticity, this review outlines the basic theories of why spontaneous recovery occurs, and introduces important principles to explain the effects of post-stroke behavioral experience on neural plasticity. Readers will be able to: (a) explain the three classic theories to explain spontaneous recovery after focal brain injury, (b) explain the neurophysiological effects of post-injury rehabilitative therapy on functional organization in motor cortex, (c) readers will be able to describe some of the variables that impact the effects of post-stroke behavioral experience on neuroplasticity, and (d) readers will be able to explain some of the current laboratory-based approaches to modifying brain circuits after stroke that might soon be translated to human application.
