AIP expression increases the growth of tectal cell dendrites. A, AIP expression increases the dendritic growth rate in all projection cells (control cells,n = 38; Ala²⁸⁶i cells,n = 44; AIP cells, n = 42).B, AIP expression has no significant effects on the dendritic growth rate of simple cells (control cells,n = 24; Ala²⁸⁶i cells,n = 28; AIP cells, n = 29).C, AIP expression increases the dendritic growth rate of complex cells (control cells, n = 14; Ala²⁸⁶i cells, n = 16; AIP cells, n = 13). D–F, AIP expression increases the branch tip number in all projection cells (D), in either simple (E) or complex (F) cells.
