Figure 4: Hippocampal astrocyte lengths. Counting of astrocyte processes length performed in the hippocampus of young rats. White arrows indicate control (upper microphotograph) and noise (lower microphotograph) representative lengths. All analyzed areas showed statistical differences between groups: GD (*P < 0.02); CA3 (*P < 0.01); and CA1 (*P < 0.02)
