Figure 7

CBD treatments protect glutamatergic synaptic densities from lesion-related losses within HVC. (a–t) Representative confocal images of immunofluorescence illustrating synaptic density in four groups: VEH Unleisoned (a–e), CBD Unlesioned (f–j), VEH Lesioned (k–o), and CBD lesioned (p–t). Stains are divided into columns with Hoechst, PSD95 (postsynaptic marker), and VGLUT2 (presynaptic marker) respectfully. Column four is a merge of PSD95 and VGLUT2 and column 5 shows a mask of the colocalized puncta. The synapse masks show that relative to VEH controls CBD groups have significantly higher glutamatergic synapse densities 24 h post-lesions.
