Serotonin was long considered a wake-promoting neurotransmitter in the brain. However, recent work by Oikonomou, Altermatt et al. (2019) showed that serotonin actually promotes sleep in both zebrafish and mice, arguing for an evolutionarily conserved sedating role. In the artwork inspired by this discovery, a sleepy mouse is reading up on the latest serotonin (also known as 5-HT) research, while his pet fish is already enjoying a good night's sleep thanks to his 5-HT-supplemented treats.
