The paper introduces an improved CNMF-based algorithm for calcium imaging data analysis, enhancing cell detection accuracy and signal quality.

The paper investigates how hippocampal CA1 neurons dynamically represent and stabilize spatial maps in mice learning a virtual-reality navigation task, showing that salient experiences like rewards reshape these maps through selective consolidation.

The paper improves cell activity estimation in calcium imaging data using non-negative matrix decomposition with shrinkage estimation and enhanced initialization methods.
