Dendritic spine density in the dentate gyrus is diminished following irradiation and is rescued with GABAergic but not glutamatergic extracellular vesicles. (A) Data represent total spine density counts along dendritic arbors across a constant region of interest in the hippocampus. Data are presented as the mean ± SEM (N = 4 animals/group). *P < 0.05, one-way ANOVA with Bonferroni's multiple comparisons test. (B) Representative images. Scale bars: 10 µm.
