... of hypothalamic monoaminergic cells in zebrafish. Fgf-signalling Serotonin Dopamine Hypothalamus Central nervous system Serotonin (5-hydroxytryptamine, 5-HT) is an ancient signalling molecule present in the nervous system of animals from cnidarian and bilaterian lineages ( Hay-Schmidt, 2000...

... signalling pathway is another component of the stress response. In Drosophila , dopamine and octopamine levels rise steeply under heat, nutrition and mechanical stresses, which are followed by a decrease in the activity of synthesis enzymes. We demonstrate that the nearly twofold decline of FOXO expression...

... snails learn to follow taste-aversion training and brain dopamine contents is not known. We examined this relationship and found the following: first, snails in the act of eating just before the commencement of CTA training were poor learners and had the highest dopamine contents in the brain; second...
