Here, we present a comprehensive behavioral test battery, including the novel tank, Shoaling, and social preference tests, to effectively determine the potential neurotoxic effects of chemicals (e.g., methamphetamine and glyphosate) on adult zebrafish using a single tank. This method is relevant to neurotoxicity and environmental research.

FAQs
Animals learn the platform location by using visual and spatial cues available around the tank rather than relying only on swimming. Across training, increasingly direct navigation toward the escape location indicates that the animal is acquiring a spatial relationship between environmental information and the platform. This makes cue-guided navigation central to interpreting learning performance.
Escape latency records how long an animal takes to reach the platform, whereas path length reflects the distance traveled before escape. Considering both measures helps describe acquisition more completely: a shorter time may accompany a more efficient route, while changes in swimming distance can provide additional context for interpreting improvement across training sessions.
A probe trial removes the immediate opportunity to escape and tests whether the animal remembers the platform's learned location. Performance during this trial therefore complements training measures: acquisition shows how the task was learned, while the platform-free challenge examines retention of the spatial information. Together, these outcomes help assess learning and memory separately.
Interpretation must account for swimming ability and motivation because poor performance may not reflect a spatial-learning deficit alone. If an animal cannot swim effectively or is insufficiently motivated to escape, escape latency and path length may worsen for noncognitive reasons. Considering these factors helps researchers avoid attributing every performance change to memory or navigation.
The experiment first provides training trials in a circular pool with a submerged escape platform, allowing the animal to learn its location from environmental cues. Researchers track escape latency and path length during acquisition. They then conduct a probe trial without the platform to evaluate memory for the previously learned location and compare the resulting behavioral measures.
Researchers apply the assay to investigate hippocampal function and to detect cognitive changes associated with brain injury, neurological disease, aging, or experimental treatments. Its value comes from linking behavioral outcomes to spatial learning and memory while retaining measures of navigation. Comparisons across these contexts can reveal whether an intervention or condition alters cognitive performance.
