Twenty years ago, estimations of the clinical incidence of ce- rebral microvascular disease approached 11 million per year in the US alone （Leary and Saver, 2003）. More recent estima- tions suggest the prevalence of diffuse white matter disease and silent brain infarction approaches 20% and increases dramatically in the presence of cardiovascular risk factors （Fanning et al., 2014）.展开更多

It appears to be well accepted, however, that changes in the ability of neurons to express plasticity accompany neurological diseases. Here, we discuss recent experimental evidence, which suggests that synaptic plasticity induced by a pathological stimulus, i.e., ischemic long-term-potentiation（i LTP） of excitatory synapses, could play an important role for post-stroke recovery by influencing the post-lesional reorganization of surviving neuronal networks.展开更多
