Effects of Model 1 (PB/PM; light red) and Model 2 (PB/DEET/CORT/DFP; dark red) on 5-HT, DA, NE and their metabolites in the spleen and brain regions (PFC, NAc, STR, AMY, dHip, vHip), as well as, inflammatory gene expression in the vHip are indicated. Modulation of these effects by LNFPIII is represented in blue color. Abbreviations: PFC: prefrontal cortex; NAc: nucleus accumbens; STR: striatum; AMY: amygdala; dHip: dorsal hippocampus; vHip: ventral hippocampus; 5-HT: serotonin; 5-HIAA: 5-hydroxyindoleacetic acid; DA: dopamine; HVA: homovanillic acid; MHPG: 3-methoxy-4-hydroxyphenylglycol; NE: norepinephrine; PB: pyridostigmine bromide; PM: permethrin; DEET: N,N-Diethyl-methylbenzamide; DFP: diisopropylfluorophosphate; CORT: corticosterone LNFPIII: lacto-N-fucopentaose III.
