Lafferman found that erythrosin B [Red 3] given to rats prevents the uptake of dopamine (the “feel good” neurotransmitter) by nerve cells in the brain called the caudate synaptosomes. This is consistent with the hypothesis that Red 3 “can act as a central excitatory agent able to induce hyperkinetic [hyperactive] behavior.”
