J Neurosurg. 2023;138(2):306-317. doi:10.3171/2022.5.JNS22411 Magnetic resonance–guided focused ultrasound (MRgFUS) thalamotomy ameliorates symptoms in patients with essential tremor (ET). How this treatment affects canonical brain networks has not been elucidated. The purpose of this study was to clarify changes of brain networks after MRgFUS thalamotomy in essential tremor patients by analyzing resting-state networks ..read more

Curr Opin Neurol. 2022;35(6):708-717. doi:10.1097/WCO.0000000000001124 A comprehensive physical examination aids in localizing (preganglionic or postganglionic) and characterizing the severity of injury (partial or complete). This is crucial to prognostication and determining the optimal reconstructive strategy. A preganglionic injury indicates an avulsion of the rootlets from the spinal cord, precludes the use of that spinal nerve as a donor for nerve grafting, and limits the reconstructive options avail ..read more

Neurology. 2022;99(24):e2648-60. doi:10.1212/WNL.0000000000201300 According to the glymphatic hypothesis, subarachnoid CSF enters the brain’s interstitial space from the periarterial space through the AQP4 channel expressed in the astrocyte end-feet and then mixes with the interstitial fluid (ISF) and waste solutes in the brain. The resulting CSF/ISF exchange and waste products, such as Aβ, are then drained out ..read more

Published online August 12, 2022:5-6. doi:10.1093/brain/awac298 There are currently no noninvasive imaging methods available for astrogliosis assessment or mapping in the central nervous system despite its essential role in the response to many disease states, such as infarcts, neurodegenerative conditions, traumatic brain injury, and infection. Multidimensional MRI is an increasingly employed imaging modality that maximizes the amount of encoded chemi ..read more
