The flatworm planaria as a toxicology and behavioral pharmacology animal model in undergraduate research experiences.

In this work we describe a series of simple protocols using planaria as an animal model in toxicology and behavioral pharmacology. These procedures have proven useful to provide significant research experience to undergraduate students, including coauthorship in peer-reviewed publications. The methods described in this work have proven useful to allow students to visualize concepts related to concentration-effect curves for toxicity and behavioral experiments, without the need to consider factors that must be taken into account when working with vertebrate animals.
