The primary auditory cortex, which was previously considered to be unisensory, has been shown to be multisensory. However, the temporal details of processing nonauditory stimuli in the human auditory cortex remain unclear, owing to the low temporal and spatial resolution of the adopted imaging techniques. ⋯ These findings provide novel evidence for multisensory interplay within human auditory cortex at an early stage of cortical processing, which extends the understanding of multisensory mechanisms of human brain functions.

Standard translaminar approaches for intradural extramedullary (IDEM) tumors require extensive soft tissue dissection and partial facet removal. Ventral lesions may necessitate wider bone resection with subsequent possible spinal instability. Any manipulation of an already compromised spinal cord may lead to neurological injury. We describe an image-guided minimal access technique for IDEM tumor resection. ⋯ Image merge tailored access resection appears to be at least equivalent in terms of tumor resection, blood loss, and complications to other tubular techniques. It may reduce risks of neurological deficit and spine instability. Image merge tailored access resection is a novel application of merging intraoperative fluoroscopic images with preoperative magnetic resonance images for tailored IDEM resection.

Although ventriculoperitoneal shunt (VPS) surgery is the most frequent surgical treatment for patients with hydrocephalus, modern rates of complications in adults are uncertain. ⋯ Complications are not infrequent after VPS surgery; however, most complications appear to be clustered in the first year after VPS insertion.

Prophylactic use of antiepileptic drugs (AEDs) for patients undergoing brain tumor surgery is common practice despite lack of clear evidence. We hypothesized that prophylactic AED (pAED) use did not affect seizure rates in patients with brain tumor who underwent craniotomy for tumor resection. ⋯ pAEDs did not significantly reduce postoperative seizures in patients with brain tumor in this analysis. In addition, pAED was often continued once prescribed even if the patient remained seizure free.

Magnetic resonance-guided laser-induced thermotherapy (MR-LITT) is a minimally invasive technique that shows promise in neuro-oncology because of its superiority in delivering precise minimally invasive thermal energy with minimal collateral damage. In this analysis, we investigate initial data on the effect of MR-LITT on dural-based lesions. ⋯ MR-LITT is a promising technology for dural-based lesion treatment. This initial study demonstrates that MR-LITT is safe and offers several advantages over open surgical treatment. Randomized studies are needed to evaluate its role as a treatment adjunct.
