Interneuronal assemblies reflect early neural reorganization after operative revascularization

The human brain is capable of remarkable spontaneous recovery after a cerebral infarct. It is now clear that brain stimulation can quantify as well as facilitate these recovery mechanisms (Khedr et al. 2005) mostly in patients with cerebral ischemic infarcts (Hummel et al. 2006). Patients with a high grade internal cerebral artery (ICA) stenosis who receive operative revascularization, allow us to monitor a well defined baseline, postoperative reperfusion and functional recovery. E.g. it is unclear how revascularization is related to compensatory mechanisms, or more specifically the role of intracortical (IC) in…
