Increased facilitation of the primary motor cortex following 1 Hz repetitive transcranial magnetic stimulation of the contralateral cerebellum in nor…

2005

Connections between the cerebellum and the contralateral motor cortex are dense and important, but their physiological significance is difficult to measure in humans. We have studied a group of 10 healthy subjects to test whether a modulation of the excitability of the left cerebellum can affect the excitability of the contralateral motor cortex. We used repetitive transcranial magnetic stimulation (rTMS) at 1 Hz frequency to transiently depress the excitability of the left cerebellar cortex and paired-pulse TMS testing of intracortical inhibition (ICI) and intracortical facilitation (ICF) to probe the excitability of cortico-cortical connections in the right motor cortex. The cortical sile…

Multimodal Intraoperative Neuromonitoring in Aneurysm Surgery

2017

Following aneurysmal subarachnoid hemorrhage, the primary goal of treatment is to exclude the vascular malformation from the intracranial circulation, while preserving the parent artery. In unruptured aneurysms, the decision whether to treat or observe the malformation is made on a case-by-case basis. In this regard, the ISUIA (International Study of Unruptured Intracranial Aneurysms) investigators suggested that aneurysm size and location were independent predictors for aneurysm rupture.1 ISUIA examined 1692 patients with cerebral aneurysms with a mean follow-up time of 4.1 years. Rupture rates differed depending on size and location, ranging from 0% in aneurysms <7 mm located in the in…
