Improvements in in vivo imaging methods have boosted research on brain asymmetry aimed at further establishing putative anatomical substrates for brain functional lateralization and particularly to explain left-hemisphere specialization for language. We analyzed volume asymmetries for major anatomical divisions of the lateral (perisylvian) brain region and(More)
OBJECTIVES To establish a methodology for mapping of primary motor cortex (M1) for cricothyroid (CTHY) muscles in a group of healthy subjects using three-dimensional (3D) magnetic resonance imaging (MRI) navigated transcranial magnetic stimulation (nTMS). METHODS Two independent measurements were performed. Twelve right-handed healthy subjects were(More)
BACKGROUND AND PURPOSE We assessed the actual frequency of motor functional MRI (fMRI) in a neurosurgical environment and estimated the extent to which it aided surgeons' identifications of the sensorimotor cortex. METHODS During five consecutive years, an fMRI protocol aimed at generating a selective activation of the hand cortical area was prescribed to(More)
The fourth cranial nerve is rarely affected by intracranial aneurysms, and when this occurs other motor ocular nerves and the trigeminal nerve are almost always involved as well. In the case reported, a middle-aged woman presented with a long-standing selective and stationary palsy of the right superior oblique muscle. Neuroradiologic studies disclosed an(More)
Despite being a common sign in focal epilepsies, the exact symptomatogenic zone for oroalimentary automatisms remains largely unknown. We describe a patient with refractory complex partial seizures secondary to a right temporoparietal malformation of cortical development who underwent prolonged video/EEG monitoring with subdural electrodes. During his(More)
We investigated whether it is possible to study the network dynamics and the anatomical regions involved in the earliest moments of picture naming by using invasive electroencephalogram (EEG) traces to predict naming errors. Four right-handed participants with focal epilepsy explored with extensive stereotactic implant montages that recorded temporal,(More)
The incidence and causes that may lead to an early end (unfinished cortical/subcortical mapping) of awake surgery for language mapping are little known. A study was conducted on 41 patients with brain glioma located in the language area that had awake surgery under conscious sedation. Surgery was ended early in 6 patients. The causes were: tonic-clonic(More)
Purpose Localizing functional regions of the cortex and deep-brain areas in epileptic patients is an important pre-surgical procedure prior to resection. This is often achieved using intra-cortical electrodes for both stimulation as well as recordings of Local Field Potentials (LFPs), concurrent to behavioral tasks related to language or motor function. To(More)
A woman aged 67 with a history of osteoarthritis of the knee was admitted to our centre to investigate a clinical history of weeks of difficulty in walking, dysaesthesia in both lower limbs and pain at the level of the spinal column. A computerised axial tomography scan (CT) and magnetic resonance imaging (MRI) were performed which revealed a well-defined(More)
We describe a case of a thoracic epidural abscess after epidural catheter insertion in a patient undergoing lobar segmentectomy. The patient described a "pulsatile" back pain the sixth day after surgery, and purulent material at the entry site of the catheter was observed. The image of the nuclear magnetic resonance confirmed an epidural abscess that was(More)
