Figure 1

Representative examples of perineuronal net (PNN+) and parvalbumin (PV)/PNN co-localized cells are shown. PNN+ cells (green channel) were identified by their complete or near complete ring structure, with relatively less intense staining in the area corresponding to the soma. PV+ cells (red channel) were identified by a staining pattern throughout most of the soma. PNN+ cells without PV are marked with arrowheads. PV+/PNN+ co-localized cells are indicated with a solid arrow. These labels are preserved when the images are separated out into the two channels and when the images are merged. The scale bar is 50 μm and applies to all images.
