\This research introduces the Network Similarity Index (NSI) , an objective tool designed to verify the quality and sufficiency of precision functional mapping (PFM) data. By quantifying how well individual brain scans align with canonical network templates , the NSI replaces subjective visual inspections with a reproducible, algorithmic framework. High NSI values indicate a well-resolved low-spat...

The research introduces current-based decomposition (CURBD) , a novel computational framework designed to map how different brain regions communicate. By using data-constrained recurrent neural networks (RNNs) , the method reproduces observed neural activity to infer the direction and strength of hidden interactions between neurons. This approach allows researchers to decompose the activity of a t...

This research identifies microglial senescence as a central driver of brain aging and cognitive decline, particularly through the shortening of telomeres . Using both mouse models and human stem cell systems, the study reveals that aged microglia release a specific protein called soluble DLK1 (sDLK1) . This ligand acts as a harmful signal that prevents oligodendrocytes from maturing and forming th...
