Ultrafast Imaging of Physiological Brain Pulsations With Magnetic Resonance Encephalography—From Noise to Predictive Clinical Biomarker

NMR in Biomedicine, Volume 38, Issue 8, August 2025.
Human brain pulsations shown in this picture drive both blood and CSF flow. These pulsations can now be accurately detected with ultrafast MREG imaging. The ultrafast imaging offers early detection of abnormal brain pulsations that can precede tissue degeneration in Alzheimer's disease or predict mortality in brain lymphoma treatment. ABSTRACT Over the

Cross‐Analysis of Single‐Cell Transcriptomic Datasets Reveals Conserved Neurogenic Gene Signatures and New Insights Into Neural Stem Cell Aging

Aging Cell, Volume 24, Issue 8, August 2025.
Here, we reanalyze single‐cell RNA sequencing datasets demonstrating hippocampal adult neural stem cell (NSC) heterogeneity to resolve classification inconsistencies and identify conserved gene markers. Our findings enhance understanding of NSC dynamics, aging, and senescence, providing a framework for standardized classification and improved insights ...
