Abstract
Zebrafish larvae exposed to artificial light at night (ALAN) showed a significant reduction in lateralisation compared to controls.
- Control zebrafish exhibited a clear lateralisation bias, favoring their right hemisphere for processing visual information.
- Exposure to ALAN resulted in a lack of lateralisation bias in zebrafish larvae.
- Zebrafish in the ALAN group demonstrated reduced individual differences in lateralisation.
- The findings suggest that ALAN may disrupt natural lateralisation, potentially impacting fish behavior and survival.
