Overview of the gene expression profiles of the serotonergic and dopaminergic genes, opioid, isotocin and the prolactin receptors in the telencephalon (tel), hypothalamus (hyp), optic tectum (opt), and rhombencephalon (rhomb) of male zebrafish 0, 30, 60, and 90 min after the treatment, whereby feed-rewarding, feed-control treatment, chasing, confinement, and air exposure were used as stressors. N = 6 per treatment. The significance value
