Separate cohort for 3, 12 and 21 month-old WT and Bdnf+/− mice were used. Following completion of behavioral assays, brain tissues were used for immunohistochemistry and BDNF assays.
Separate cohort for 3 and12 month-old WT and Bdnf+/− mice were used.
Separate cohort for 3, 12 and 21 month-old WT and Bdnf+/− mice were used. DAT activity was determined from striatum of individual animals
Separate cohort for 3, 12 and 21 month-old WT and Bdnf+/− mice were used. Synaptic vesicles were prepared from pooled striatal tissue derived from three age and genotype matched animals (n=1).
ND: Not determined
