Distribution of Modulatory Neurotransmitters in the Zebrafish and Human Brain. (A) Distribution of DA in the zebrafish (left) and human (right) brains (red); (B) Distribution of NE in zebrafish (left) and human (right) brains (blue); (C) Distribution of 5-HT in zebrafish (left) and human (right) brains (green); (D) Distribution of ACh in zebrafish (left) and human (right) brains (yellow); (E) Distribution of histamine in zebrafish (left) and human (right) brains (purple). Brains are not to scale with some simplification of systems that are represented. DA, dopamine; NE, norepinephrine; 5-HT, serotonin; ACh, acetylcholine. Neurotransmitter distributions synthesized from [16,127,128,129,130,131,132,133].
