Spontaneous restorative plasticity is reported frequently after stroke. To test whether conditions in perinfarct cortex facilitate plastic changes, we examined experience-dependent plasticity of cortical functional representation of vibrissae in rat brain after focal photothrombotic stroke. Cortical activation was visualized with [C]2-deoxyglucose. To(More)
Although stroke can affect cerebral structure and function, the brain has a potential for plasticity thanks to which some degree of function can be restored. The pathways of such recovery are of great interest, since the dynamics of rewiring of the injured brain may become the basis for designing appropriate strategies of rehabilitation. We investigated the(More)
Brain injury triggers spontaneous plasticity, often resulting in considerable restoration of function. To investigate mechanisms of this compensatory plasticity we followed changes in the brain's pattern of activation evoked by stimulation of vibrissae, after a focal cortical stroke which destroyed the cortical representation of vibrissae, the barrel(More)
Despite indications that brain plasticity may be enhanced after stroke, we have described impairment of experience-dependent plasticity in rat cerebral cortex neighboring the stroke-induced lesion. Photothrombotic stroke was centered behind the barrel cortex in one cerebral hemisphere of rats. Plasticity of cortical representation of one row of vibrissae(More)
