(A) Mean±SE NGF protein concentration (pg/mg of tissue) for each brain region. The Young group had lower concentrations of NGF in the frontal cortex, parietal cortex, temporal cortex, and striatum. (B) Represented is the scatterplot of ventral hippocampal (CA1/2) concentrations of NGF (pg/mg tissue) in aged (23 month old) females (black filled triangles) and males (gray filled circles), and the number of correct arm choices made on the T-Maze during the first training session when young, 17 months earlier (at 6 months old). (C) Represented is the scatterplot of frontal cortex concentrations of NGF (pg/mg tissue) in aged (23 month old) females (black filled triangles) and males (gray filled circles), and the number of correct arm choices made on the T-Maze during the first training session when young, 17 months earlier (at 6 months old). Higher concentrations of NGF in the aged ventral hippocampus (CA1/2) and frontal cortex, significantly correlated with better initial spatial reference memory performance when young, in females only, as represented by the black solid line. F=females, M=males, * p <0.05.
