AC administration administration prior to PTSD increased the number of BDNF-like immunoreactive cells to 42.63 ± 6.49 (61.39 ± 9.35%), compared 53.00 ± 5.77 (68.66 ± 7.48%) in the CA3 hippocampal area of rats not administered AC (p < 0.05). This evidence concerns the gene BDNF and post-traumatic stress disorder.
