We provide a synopsis of innovative research, recurring themes, and novel experimental findings pertinent to the care of neurosurgical patients and critically ill patients with neurological diseases. The following broad topics are covered: general neurosurgery, spine surgery, stroke, traumatic brain injury, anesthetic neurotoxicity, perioperative cognitive dysfunction, and monitoring.

Case ReportsEffects of Insula Resection on Autonomic Nervous System Activity.
The insula is an essential component of the central autonomic network and plays a critical role in autonomic regulation in response to environmental stressors. The role of the insula in human autonomic regulation has been primarily investigated following cerebrovascular accidents, but interpretation of these findings is complicated by lack of control over time-related processes preceding and following cerebrovascular accidents. Surgical resection of tumors in the insula provides unique information about the neural circuits of autonomic dysregulation and subsequent cardiac arrhythmias. ⋯ These findings suggest that the right insula plays a critical role in parasympathetic autonomic modulation and subsequent cardiac arrhythmias. Additional research is needed to establish the long-term effects of right versus left insula resection as related to autonomic dysregulation and adverse brain-heart interactions, particularly in patients at risk of cardiac arrhythmias.

Transcranial Color Duplex Ultrasound: A Reliable Tool for Cerebral Hemodynamic Assessment in Brain Injuries.
Transcranial color duplex ultrasound (TCCD) is becoming an important tool for cerebral monitoring of brain-injured patients. To date, TCCD reproducibility has been studied in healthy volunteers or patients with subarachnoid hemorrhage and its efficiency in many brain injuries has not been proved. Our aim was to evaluate TCCD interobserver agreement in different brain injuries. ⋯ We reported the reliability of TCCD interobserver agreement in brain-damaged patients.
