Density and diameter of ChAT+ varicosities and length of ChAT+ fiber segments within microproximity of Pyramidal cells in Layer V of mPFC.

All values are means ± SEM in visual/HDB stimulation rats and control rats. Density of ChAT+ varicosities is expressed in number of varicosities/µm of ChAT+ fiber segment. Diameter of ChAT+ varicosities is expressed in nm. ChAT+ fiber length is expressed in µm.
