Changes in aminoacidergic and monoaminergic neurotransmission in the hippocampus and amygdala of rats after ayahuasca ingestion

Figure 3 Utilization rate of monoamines. Hippocampus (A) and Amygdale (B). The utilization rate was estimated as a ratio between metabolite/ neurotransmitter concentrations: VMA: 4-hydroxy-3-methoxy mandelic acid; NA: Norepinephrine; DA: Dopamine; 5HIAA: 5-hydroxyindoleacetic acid; HVA: 4-hydroxy-3-methoxy-phenylacetic acid; 5HT: 5-hydroxytryptamine. The bars represent mean ± SD of ratio. The results were evaluated by Analysis of variance followed by Scheffé test. (^aP < 0.05 vs saline).
