Conditional approach as cooperation in predator inspection: a role for serotonin?

Abstract

17increased the time the animal spent inspecting the predator image, while metergoline decreased 31 it. Fluoxetine also decreased time spent avoiding the predator and increased freezing, while 32 metergoline decreased freezing. These results suggest that phasic increases in serotonin levels 33 promote conditional approach, suggesting a role for this neurotransmitter in cooperation. 34 Preprint: https://doi.org/10.1101/436345; Data and scripts: https://github.com/lanec-35 unifesspa/TFT 36
