  • *, E18; **, P14;

  • , P5; ++, strong expression; +, moderate or weak expression; ±, faint or none. p indicates that the expression is limited to some areas, layers, and cells. Not all the positive regions are indicated here. At E15 and P2, OL-pc seemed to be expressed, at least faintly, in almost all regions of the brain. Those items left blank are those that were not well examined, in part because identifying these brain nuclei was difficult because of the immaturity of development. Abbreviations are listed separately in .
