Δ9‐THCA prevents neuronal loss, microgliosis and astrogliosis induced by 3‐NPA administration. (A) Representative images of Nissl, Iba‐1 and GAFP staining performed on coronal striatal brain sections (original magnification 20×). (B) Quantification of the different markers was performed with ImageJ software. Total average number of neurons (Nissl), microglia (Iba‐1+) and astrocytes (GFAP+) is shown. Values are expressed as means ± SEM (n = 6). *
P < 0.05, significantly different from control group; #
P < 0.05, significantly different from 3‐NPA group (n = 9 animals per group).
