Neural and Behavioral Dynamics of Acute Fentanyl Administration and Implications for Hazard Assessment of Novel Synthetic Opioids in Larval Zebrafish

Courtney Hillman, James Kearn, Gabrielle Wasser‐Bennett…·Matthew O. Parker

This study uses larval zebrafish to assess the behavioral and neural effects of fentanyl and other synthetic opioids, identifying potential mechanisms and validating a scalable model for hazard assessment.

A Unified Approach to Investigating 4 dpf Zebrafish Larval Behaviour through a Standardised Light/Dark Assay

Courtney Hillman, James Kearn, Matthew O. Parker

This paper develops a standardised light/dark assay for 4 dpf zebrafish larvae to study behaviour, showing optimal transition periods and validating it with ethanol and transgenic larvae.
