Implementation of the neuro-glia-vascular unit through co-culture of adult neural stem cells and vascular cells and transcriptomic analysis of diverse Aβ assembly types J. Neurosci. Methods (IF 3.0) Pub Date : 2023-12-01 Chaejeong Heo, Hee-Jin Kwak, Long Hoang Ngo, Ran-Sook Woo, Sook-Jeong Lee
Background The blood-brain barrier (BBB) is a specialized layer between blood vessels and tissue in the brain, which is comprised of a neuro-glia-vascular (NGV) unit, thus play a vital role in various brain diseases. New method We developed the in vitro NGV units by co-culturing brain microvascular endothelial cells (BMECs; bEnd.3) and primary neural stem cells extracted from subventricular zone of

Behavioral phenotyping based on physical inactivity can predict sleep in female rats before, during, and after sleep disruption J. Neurosci. Methods (IF 3.0) Pub Date : 2023-11-30 Kora N. Kostiew, Diya Tuli, Jamie E. Coborn, Christopher M. Sinton, Jennifer A. Teske
Background A noninvasive method that can accurately quantify sleep before, during, and after sleep disruption (SD) has not been validated in female rats across their estrous cycle. In female rats, we hypothesized that the duration of physical inactivity (PIA) required to predict sleep would 1) change with the differences in baseline sleep between the circadian and estrous cycle phases and 2) predict

fNIRS-based graph frequency analysis to identify mild cognitive impairment in Parkinson’s disease J. Neurosci. Methods (IF 3.0) Pub Date : 2023-11-29 Zhilin Shu, Jin Wang, Yuanyuan Cheng, Jiewei Lu, Jianeng Lin, Yue Wang, Xinyuan Zhang, Yang Yu, Zhizhong Zhu, Jianda Han, Jialing Wu, Ningbo Yu
Background: Early identification of mild cognitive impairment (MCI) is essential for its treatment and the prevention of dementia in Parkinson’s disease (PD). Existing approaches are mostly based on neuropsychological assessments, while brain activation and connection have not been well considered. New Method: This paper presents a neuroimaging-based graph frequency analysis method and the generated

Quantifying GFAP immunohistochemistry in the brain – Introduction of the Reactivity score (R-score) and how it compares to other methodologies J. Neurosci. Methods (IF 3.0) Pub Date : 2023-11-28 Lauren Luijerink, Michael Rodriguez, Rita Machaalani
Background Immunohistochemical upregulation of glial fibrillary acidic protein (GFAP) is commonly used to detect astrogliosis in tissue sections and includes measurement of intensity and/or distribution of staining. There remains a lack of standard objective measures when diagnosing astrogliosis and its severity. New method Aim was to test a novel semi-quantitative assessment of GFAP which we term
