Changes in the content of brain biogenic amine associated with early colony establishment in the Queen of the ant, Formica japonica.

We examined changes in the content of biogenic amines in the brains of ant queen associated with early colony establishment. In ants, including Formica japonica, winged virgin queens lose their wings following copulation, and then start establishing a colony. Significant changes in brain biogenic am...
