Percentages of neurons immunoreactive for the calcium-binding proteins PARV, CALR, and CALB, showing positive hybridization for NGF and NT3 mRNAs, with respect to the number of immunoreactive neurons. Data are presented for the different hippocampal subfields (CA1, regio superior; CA3, regio inferior; H, hilus; DG, dentate gyrus), and for the entire hippocampus (TOTAL). The percentage of calcium-binding protein/PHAL-labeled neurons showing NGF or NT3 hybridization (triple-labeled neurons) with regard to the number of double-labeled cells (calcium-binding protein/PHAL-positive) is also indicated. The number of cells counted is indicated in parentheses.
