EGR1 and migraine disorder: What’s more noteworthy was that, in addition to the changes in the brain regions that were clearly related to migraine, more Egr1 positive cells were found in primary somatosensorycortex (SSp) (p = 0.001, VEH: 45.369 ± 3.544 vs. NTG: 63.640 ± 2.858, Figures 2A–C), VISp (p = 0.0153, VEH: 53.339 ± 1.919 vs. NTG: 60.192 ± 1.642, Figures 2D–F), lateral amygdala nucleus (LA) (p = 0.0015, VEH: 11.498 ± 2.569 vs. NTG: 22.991 ± 1.558, Figures 2G–I), and temporal association areas (TEa) (p = 0.0063, VEH: 17.237 ± 2.485 vs. NTG: 27.482 ± 2.116, Figures 2J–L) compared with the control group.
