Social Hierarchy: Even for Mice, It’s Complicated

Studying wild mice in near-natural conditions reveals different strategies used by females and males in forming social hierarchies

Lighting up the reward center: Light-sensitive proteins are inserted into specific brain cells. Blue: dopamine-producing cells in the reward system in the ventral tegmental area. Red: cells carrying the inserted protein in a mouse brain. Yellow: Overlap between cells that are carrying the optogenetic protein and those that are dopamine-producing.
