All values are obtained p values of group-specific effects in the c-Fos immunoreactivity and ChAT+ varicosity density/diameter and ChAT+ fiber length within microproximity of pyramidal cells in 4 groups of rats: control, visual stimulation only, HDB stimulation only, and visual/HDB stimulation. Symbol* indicates significant p values (Mann-Whitney U test, p≤0.05, two-tailed).
