Percentage of individuals across DA doses exhibiting a behavioral response to exposure to PTZ within 20 min observation. Fish that exhibited a writhing motion or convulsive-only motion without a definable whirlpool action were grouped as other movements. “Deformities” include the percentage of fish whose physical deformities from DA prohibited them from exhibiting stage II seizures. The number of 0.13-ng/mg DA-exposed larvae responding is comparable to 0 ng/mg and has been omitted. PTZ doses > 5 mM exhibited 100% response across all DA doses (data not shown).
