mechanisms that likely include alterations in synaptic efficacy in the hippocampus. To
address this issue, we exposed mice to a single episode of voluntary exercise, and
permanently marked activated mature hippocampal dentate granule cells using conditional
Fos-TRAP mice. Exercise-activated neurons (Fos-TRAPed) showed an input-selective
increase in dendritic spines and excitatory postsynaptic currents at 3 days post-exercise …
