shank3b ?/? zebrafish displayed social interaction defect. a?b Schematic of shoaling test (a) and significantly increased inter-fish distance of adult male shank3b?/? zebrafish (3.5 mpf) (b). N?=?18 for each group. c?f Schematic of social preference test of adult male zebrafish (3.5 mpf) (c). Heat map (d) shows that shank3b +/+ zebrafish displayed significant higher frequency near a group of zebrafish than shank3b ?/? zebrafish. Time ratio (e) and distance ratio (f) in the conspecific sector were significantly reduced in shank3b ?/? zebrafish compared to shank3b +/+ zebrafish. N?=?16 for each group. g?h Schematic of kin recognition and preference test of adult male zebrafish (3.5 mpf) (g) and significantly reduced ratio of kin zone entering in shank3b ?/? zebrafish compared to shank3 +/+ zebrafish (h). N?=?10 for each group. Data are presented as mean?±?SEM; ****p?< 0.0001
