BACKGROUND: Nowadays, there is a general trend in vestibular schwannoma (VS) surgery favoring near-total or subtotal tumor resection (NTR/STR) with facial nerve (FN) function preservation rather than gross total resection (GTR) with high risk of FN damage. METHODS: The surgical technique of FN sparing in large VS includes patient-tailored image-guided craniotomy, continuous intraoperative neurophysiological monitoring (INM), intracapsular wide tumor debulking, and only final extracapsular dissection with FN course identification and brainstem decompression...

OBJECT: To assess the clinical and radiographic outcomes of posterior vertebral column resection (PVCR) without anterior support in treatment of Yang's A type severe rigid thoracic kyphoscoliosis. METHODS: The records of 27 Yang's A type severe thoracic kyphoscoliosis patients treated with PVCR without anterior support from January 2010 to September 2013 were retrospectively analyzed. Intraoperative multimodal neurophysiological monitoring (IONM) (6 modes: Somatosensory evoked potential (SSEP), Motor evoked potential (MEP), Descending neurogenic evoked potential (DNEP), Spinal cord evoked potential (SCEP), and Electromyography, both triggered and free run EMG) was conducted in all patients...

BACKGROUND: Temporary arterial occlusion (TAO) is a valuable tool for minimizing intraoperative rupture risk during intracranial aneurysm microsurgery; however, it may also be associated with ischemic injury. OBJECTIVE: This study aims to identify surgical and intraoperative neurophysiological monitoring (IONM) factors that predict perioperative stroke risk after TAO. METHODS: We performed a retrospective chart review of 177 intracranial aneurysm surgeries at our institution, in which TAO was performed before the placement of a permanent clip under monitoring with somatosensory evoked potentials (SSEPs) and electroencephalography (EEG)...

Intramedullary spinal cord tumors (IMSCTs) represent a rare entity, accounting for 4%-10% of all central nervous system tumors. Microsurgical resection of IMSCTs is currently considered the primary treatment modality. Intraoperative neurophysiological monitoring (IONM) has been shown to aid in maximizing tumor resection and minimizing neurological morbidity, consequently improving patient outcome. The gold standard for IONM to date is multimodality monitoring, consisting of both somatosensory evoked potentials, as well as muscle-based transcranial electric motor evoked potentials (tcMEPs)...

Chemotherapy induced peripheral neuropathy (CIPN) is a significant toxicity of cancer treatment, with the potential to affect long-term function and quality of life in cancer survivors. There remains a lack of consensus around optimal assessment techniques. While current approaches to CIPN assessment are focused on clinical grading scales, it is becoming increasingly evident that a more comprehensive multimodal assessment package is necessary to accurately characterise the impact of CIPN as well as gauge the utility of neuroprotective mechanisms...

Cognitive control is relevant when distracting information induces behavioral conflicts. Such conflicts can be produced consciously and by subliminally processed information. Interestingly, both sources of conflict interact suggesting that they share neural mechanisms. Here, we ask whether conjoint effects between different sources of conflict are modulated by microstructural basal ganglia dysfunction. To this end, we carried out an electroencephalography study and examined event-related potentials (ERPs) including source localization using a combined flanker-subliminal priming task in patients with X-linked dystonia Parkinsonism (XDP) and a group of healthy controls...

The regulation of micturition involves complex neurophysiologic pathways, and its understanding has grown immensely over the past decade. Alternative approaches and applied technologies in the treatment of bladder dysfunction have minimized the complications that result from neurogenic bladder. The use of natural bladder mechanoreceptors and electroneneurographic (ENG) signal recordings from afferent nerves to chronically monitor bladder volume is a promising concept, but the technology to accomplish this has proven to be a great biomedical engineering challenge...

Introduction: Smoking abstinence is theorized to increase smoking reinforcement and decrease nondrug reinforcement. A separate literature demonstrates the detrimental effects of abstinence on cognition. The present study integrates these two areas by examining the separate and combined effects of reinforcement and smoking abstinence on behavior and a neurophysiological index of response monitoring (ie, error-related negativity [ERN]) during a cognitive task. Methods: After a screening visit, adult smokers attended two laboratory visits, once while smoking and once while abstinent...

AIM: Neurosurgical oncology that is performed for lesions located in critical areas like the sensorimotor area has additional risk because it may cause serious neurological deficiencies. Some intraoperative neuromonitoring (IONM) modalities can effectively help the surgeons to maximize resections of this kind of lesions with or without an acceptable neurological deficiency. Our aim was to share our IONM experiences with patients who underwent intracranial lesion surgery in critical areas between September 2013 and January 2015...

Characterizing the neurobiology of schizophrenia and other major psychiatric disorders is one of the main challenges of the current research in psychiatry. The availability of Transcranial Magnetic Stimulation (TMS) allows to directly probe virtually any cortical areas, thus providing a unique way to assess the neurophysiological properties of cortical neurons. This article presents a review of studies employing TMS in combination with Motor Evoked Potentials (TMS/MEPs) and high density Electroencephalogram (TMS/hd-EEG) in schizophrenia and other major psychiatric disorders...

BACKGROUND: Post-traumatic stress disorder (PTSD) is often associated with attention allocation and emotional regulation difficulties, but the brain dynamics underlying these deficits are unknown. The emotional Stroop task (EST) is an ideal means to monitor these difficulties, because participants are asked to attend to non-emotional aspects of the stimuli. In this study, we used magnetoencephalography (MEG) and the EST to monitor attention allocation and emotional regulation during the processing of emotionally charged stimuli in combat veterans with and without PTSD...

Anesthesiologists work to prevent or minimize secondary injury of the nervous system and improve the outcome of medical procedures. To this end, anesthesiologists must have a thorough understanding of pathophysiology and optimize their skills and equipment to make an anesthesia plan. Anesthesiologists should conduct careful physical examinations of patients and consider neuroprotection at preoperative interviews, consider cervical spinal cord movement and compression during airway management, and suggest awake fiberoptic bronchoscope intubation for stable patients and direct laryngoscopy with manual in-line immobilization in emergency situations...

Understanding the brain mechanisms involved in diagnostic reasoning may contribute to the development of methods that reduce errors in medical practice. In this study we identified similar brain systems for diagnosing diseases, prescribing treatments, and naming animals and objects using written information as stimuli. Employing time resolved modeling of blood oxygen level dependent (BOLD) responses enabled time resolved (400 milliseconds epochs) analyses. With this approach it was possible to study neural processes during successive stages of decision making...

REVIEW
Shintaro Funahashi
The prefrontal cortex participates in a variety of higher cognitive functions. The concept of working memory is now widely used to understand prefrontal functions. Neurophysiological studies have revealed that stimulus-selective delay-period activity is a neural correlate of the mechanism for temporarily maintaining information in working memory processes. The central executive, which is the master component of Baddeley's working memory model and is thought to be a function of the prefrontal cortex, controls the performance of other components by allocating a limited capacity of memory resource to each component based on its demand...

Sugammadex is a novel pharmacologic agent, which reverses neuromuscular blockade (NMB) via a mechanism that differs completely from acetylcholinesterase inhibitors. By encapsulating rocuronium, sugammadex can provide recovery of neuromuscular function even when there is a profound degree of NMB. We report anecdotal experience with the use of sugammadex to reverse NMB to facilitate intraoperative neurophysiological monitoring (motor evoked potentials) in an adolescent with scoliosis during posterior spinal fusion...

PURPOSE: Although there are guidelines analyzing transcranial motor evoked potentials (MEP) waveform criteria, they vary widely and are not applied universally during intraoperative neurophysiologic monitoring (IONM). The objective is to generate hypotheses to identify early and reliable MEP waveform characteristics prior to complete loss of MEP to predict impending motor spinal cord injuries during spinal surgeries. The ultimate goal is to enhance real-time feedback to prevent injury or detect reversible spinal cord damage...
