Ai) Change in gamma power relative to baseline in soman-exposed rats that received MDZ + 10 mg/kg ganaxolone (red, n=9) or MDZ + 50% HPBCD in water (blue, n=9). Aii) Change in mean spike rate frequency relative to baseline in soman-exposed rats that received MDZ + 10 mg/kg ganaxolone (red, n=9) or MDZ + 50% HPBCD in water (blue, n=9). Aiii) Fluoro-Jade B staining in vulnerable brain regions in soman-exposed rats that received MDZ + 10 mg/kg ganaxolone (red, n=7) or MDZ + 50% HPBCD in water (blue, n=11). Bi) Change in gamma power relative to baseline in DFP-exposed rats that received MDZ + 10 mg/kg ganaxolone (red, n=19) or MDZ + 50% HPBCD in water (blue, n=20). Bii) Change in mean spike rate frequency relative to baseline in DFP-exposed rats that received MDZ + 10 mg/kg ganaxolone (red, n=19) or MDZ + 50% HPBCD in water (blue, n=20).
