Retrograde injections sites are suffixed with a FB, DY, or FG for Fast Blue, Diamidino Yellow, or Fluorogold, respectively.

¹For experiment 99DY, the injection site was excluded from analyses as there was negligible labeling due to superficial location of site.

²Experiment 108 FG encroached slightly on LEA. Other abbreviations: L, lateral dentate gyrus-projecting band; I, intermediate band; M, medial band.
