Measurement of natural variation of neurotransmitter tissue content in red harvester ant brains

Colonies of the red harvester ant regulate foraging activity based on food availability and local conditions. Here we quantified tissue content of 4 biogenic amines (dopamine, serotonin, octopamine, and tyramine) in single forager brains from 9 red harvester ant colonies collected in the field. Capillary electrophoresis coupled with fast-scan cyclic voltammetry (CE-FSCV) was used to separate and...
