Effect of NYT on social behavior on mirror test in NPY-KO zebrafish. NPY-KO zebrafish were fed a control or NYT-diet twice daily for 4 days. Their social behaviors, such as interaction with the mirror and swimming distance, were estimated using a mirror test. (A) Mirror test apparatus. (B) Experimental scheme for behavioral evaluation. (C) Daily food intake. (D) Total distance traveled. (E) Tracking of control (left) and NYT-fed zebrafish (right) swimming behavior. (F) Total time for interaction with the mirror. (G) Total number of interactions with mirror. n = 8. Results are shown as mean ± standard error of the mean. n.s., not significant.
