Long-term exercise training preserves dendritic spine density, synapses, and synaptic vesicles of TgF344-AD rats. A Representative images of Golgi staining of cortex and hippocampus. Selected dendritic segments from the cortex and hippocampus were skeletonized using ImageJ software and analyzed. B Representative images of synapses in cortex and hippocampus. The numbers of synapses and synaptic vesicles per pre-synaptic bouton were counted and analyzed. All data are expressed as mean ± SEM (n = 4). *P < 0.05 versus WT group, ^#P < 0.05 versus AD group
