Cognitive and Neural Impacts of Pregnancy in Poeciliopsis Fish

Tiffany Ernst published raw data from a study on the live-bearing fish Poeciliopsis gracilis. The 1.4 MB dataset includes performance metrics from spatial learning, reversal learning, and habituation tasks, along with cell proliferation measurements in the brain. It is linked to a peer-reviewed article in the European Journal of Neuroscience and was last updated on 2026-05-28.

Use Cases

• Compare cognitive performance between pregnant and virgin fish based on spatial learning task data.
• Analyze behavioral flexibility based on reversal learning task data.
• Investigate the relationship between pregnancy and brain cell proliferation based on ki67+ coverage measurements.
• Replicate or extend the analysis from the associated published research article.

Strengths

• Dataset is linked to a peer-reviewed publication in the European Journal of Neuroscience.
• Includes raw data for multiple experimental phases: habituation, associative learning, spatial learning, and reversal learning.
• Published under a CC-BY-4.0 license, allowing for reuse with attribution.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect species-specific bias inherent to the single-species study.
