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

**Mimi Shin, Daniel A. Friedman, Deborah M. Gordon, B. Jill Venton** (2020) · Entomology

## Instructions

Use this skill when working with topics related to **neurotransmitters, dopamine, serotonin, octopamine**.

When applying this skill:
1. Apply CE-FSCV for single-brain neurotransmitter quantification
1. Measure natural variation in biogenic amines across social insect colonies
1. Design analytical chemistry approaches for ecologically relevant neurochemistry

## Key Concepts

- **neurotransmitters**
- **dopamine**
- **serotonin**
- **octopamine**
- **tyramine**
- **Pogonomyrmex barbatus**
- **CE-FSCV**
- **biogenic amines**
- **colony variation**

## Methods & Techniques

- Utilized capillary electrophoresis with fast-scan cyclic voltammetry (CE-FSCV) for neurotransmitter detection.
- Field-amplified sample stacking was employed to enhance detection limits of neurotransmitters in single ant brains.
- Ant brains were dissected and homogenized in a controlled environment to prepare samples for analysis.
- Statistical analysis was performed using GraphPad Prism to evaluate variations in neurotransmitter content.

## Key Findings

- Dopamine was found to be the most abundant biogenic amine, followed by octopamine, serotonin, and tyramine.
- Significant variation in neurotransmitter content was observed among different ant colonies.
- The relative standard deviation of neurotransmitter levels was lower within colonies compared to across colonies.
- Correlations were noted between levels of octopamine, tyramine, and serotonin, but not with dopamine.

## Prerequisites

- Evolutionary biology and ecology fundamentals
- Social insect biology and colony organization
