Brain lipids are organized into zones — and reorganized during pregnancy

TL;DR - A whole-mouse-brain map reveals that lipids are spatially organized into distinct zones and that this organization changes during pregnancy. This lipid architecture differs from patterns captured by gene-expression and protein atlases.

• Maps the distribution of fats across the entire mouse brain.
• Identifies a spatial organization not evident in transcriptomic or proteomic maps.
• Reports pregnancy-associated reorganization of brain lipid zones.
• The provided excerpt does not specify the mapping methods, lipid classes, or functional consequences.
