Figure 3From: Systemic lipopolysaccharide-mediated alteration of cortical neuromodulation involves increases in monoamine oxidase-A and acetylcholinesterase activity Systemic LPS induces transient effects in the tail suspension test and an increase in nitric oxide production. (A) Histograms comparing the latency to the first immobility and total immobility time at 1 day (N = 10, *P < 0.05, unpaired t-test) versus 7 days (N = 8, unpaired t-test) post LPS treatment. (B) Histogram showing nitrate/nitrite levels of hemi-brain homogenates collected 7 days post LPS treatment (N = 9 per group; *P < 0.001, unpaired t-test) LPS, lipopolysaccharide.Back to article page
