Cerebrovascular imaging is critical for safe and accurate planning of Stereo-ElectroEncephaloGraphy (SEEG) electrode trajectory. We developed a new technique for Cone Beam Computed Tomography (CBCT) Three-Dimensional Digital Subtraction Angiography (3D DSA). ⋯ CBCT 3D DSA is a safe diagnostic procedure for SEEG electrode trajectory planning and for 3D reconstructions of the vascular tree in multimodal scenes for resections. The high fidelity and geometric accuracy contribute to the safety of electrode implantation.

Induction of Fear by Intraoperative Stimulation During Awake Craniotomy: Case Presentation and Systematic Review of the Literature.
A case is presented and a systematic review of the literature is provided to update our current knowledge of induction of fear by cortical stimulation. ⋯ Although our observation suggests that this area of the brain could be part of a network involved in the elicitation of fear, dysfunction of this network induced by epilepsy could also explain the observed phenomenon. Electrophysiologic and imaging studies must be conducted to improve our understanding of the cortical networks forming the neuroanatomical substrate of higher brain functions and experiences such as fear.

Patients with Parkinson disease (PD) often suffer from a resting tremor, bradykinesia, rigidity, postural instability, and gait difficulty. Determining a patient's candidacy for deep-brain stimulation (DBS) surgery and tracking their clinical response postoperatively requires that the frequency, duration, and severity of these symptoms be characterized in detail. ⋯ In this article, we review the role of accelerometers in surgical candidate selection, recording and predicting falls, recording and predicting freezing of gait, evaluating surgical outcomes, and evaluating postoperative recovery and in altering DBS settings. Although accelerometry has yet to make it into the mainstream clinic, there is great promise for this technology in monitoring Parkinson patients.

Guillain-Barré syndrome (GBS) is an acute peripheral neuropathy caused by an autoimmune response against myelin of peripheral nerves. GBS has been reported after surgery, in general, and after spinal surgery, in particular. In most cases, GBS developed 1-3 weeks after surgery. ⋯ GBS developing acutely after spinal surgery is a rare occurrence but should be considered in the differential diagnosis of neurological deterioration after surgery. Rapid diagnosis and treatment are essential for recovery of neurological function.
