Preoperative DTI Fiber Tracking (DTI-FT) reconstruction of functional tracts combined with intraoperative subcortical mapping (ISM) is potentially useful to improve surgical procedures in gliomas located in eloquent areas. Aims of the study are: (1) to evaluate the modifications of fiber trajectory induced by the tumor; (2) to validate preoperative DTI-FT(More)
Studies describing subthalamic (STN) local field potentials (LFPs) recorded during deep brain stimulation (DBS) in patients with Parkinson's disease (PD), within the first month after DBS electrode implant, show that DBS modulates specific STN oscillations: whereas low-frequency (LF) oscillations (2-7 Hz) increase, beta oscillations (8-30 Hz) variably(More)
Glioblastomas represent an important cause of cancer-related mortality with poor survival. Despite many advances, the mean survival time has not significantly improved in the last decades. New experimental approaches have shown tumor regression after the grafting of neural stem cells and human mesenchymal stem cells into experimental intracranial gliomas of(More)
OBJECTIVE Subcortical stimulation can be used to identify functional language tracts during resection of gliomas located close to or within language areas or pathways. The objective of the present study was to investigate the feasibility of the routine use of subcortical stimulation for identification of language tracts in a large series of patients with(More)
BACKGROUND Patients aged 65 years and older are not traditionally considered optimal candidates for subthalamic deep brain stimulation (STN-DBS), mainly for their presumed increased incidence of surgical complications. The aim of this study was to assess STN-DBS surgery safety in relation to age. METHODS A total of 107 consecutive patients undergoing(More)
The brain's plasticity in response to sensory deprivation and other perturbations is well established. While the functional properties of the reorganized areas are under vigorous investigation, the factors that constrain cortical reorganization remain poorly understood. One factor constraining such reorganization may be long-distance subcortical(More)
OBJECTIVE We report, for the first time, the occurrence of interference between a Cavitron ultrasonic surgical aspirator (CUSA) and intraoperative brain mapping performed by direct electrical stimulation (DES). METHODS Intraoperative polygraphic recordings (electrocorticogram and electromyogram) were gathered from a 44-year-old patient harboring a(More)
BACKGROUND Cavernous hemangioma are the most common benign lesions of the orbit. Their surgical resection is still challenging and several surgical approaches have been proposed. CASE DESCRIPTION We present the case of a 59-year-old woman with a cavernous hemangioma of the orbital apex, which was diagnosed incidentally. The hemangioma was extraconal and(More)
Intraoperative neuronal microrecordings can help in localizing the subthalamic nucleus (STN) during stereotactic neurosurgery for deep-brain stimulation (DBS) in Parkinson's disease. To obtain quantitative information on neuronal spike descriptors, we systematically analysed neuronal spikes in the STN and substantia nigra pars reticulata (SNr) in 31 sides(More)
