The objective of this study was to investigate the effects of exposure to rotenone, sleep deprivation, and the epidermal growth factor receptor (EGFR) inhibitor on the locomotor activity of zebrafish larvae. Observations were conducted on control groups, sleep-deprived groups without interventions, groups treated with rotenone or the EGFR inhibitor alone, and also groups with combined exposures. The results showed that sleep deprivation alone led to a decrease of speed of the locomotor activity compared to the control groups. The treatment with rotenone alone resulted in varied effects on the locomotor activity. However, a combined exposure to rotenone and sleep deprivation further reduced the locomotor activity compared to the control and rotenone-treated groups. The groups treated with the EGFR inhibitor alone exhibited variable effects on the locomotor activity. Furthermore, the combined exposure to the EGFR inhibitor and sleep deprivation resulted in diverse changes in the locomotor activity. However, the combined treatment with rotenone and the EGFR inhibitor produced complex alterations in the locomotor activity. These findings demonstrate the distinct effects of exposure to rotenone, sleep deprivation, and the EGFR inhibitor on the locomotor activity of zebrafish larvae. The interaction between these factors further modulates locomotor activity, suggesting a potential interplay between the EGFR system, sleep regulation, and the dopaminergic system. Understanding the relationship between the EGFR system, sleep regulation, and neurological regulation may contribute to the development of therapeutic strategies to address such issues as sleep disorders and neurodegenerative conditions. •Sleep deprivation decreased larval swimming speed, aligning with previous sleep deprivation research.•Results indicate sleep deprivation, rotenone, EGFR inhibitor and combination influenced larval swimming abilities.•Sleep deprivation exacerbated rotenone's effects on swimming speed.
