The microbiological status of the flies had a small or no effect on anxiety-like behavior (centrophobism) or circadian rhythmicity of locomotor activity, but axenic flies tended to sleep for longer and displayed reduced sleep...

In the present experiments, the spontaneous exploratory behavior of isolated crayfish was analyzed in a DLPM at different stages of their molt cycle. All tested animals displayed...

... (thigmotaxis), a measure of anxiety in vertebrates, is significantly reduced in Schistocephalus -infected sticklebacks, unveiling a new altered component of behaviour that may result from manipulation by this macroparasite. * Author for correspondence ( Nadia.Aubin-Horth@bio.ulaval.ca ) Competing...

... clarkii ) have established that stress induces changes in brain serotonin (5-HT) concentrations that are responsible for the appearance of anxiety-like behavior (ALB). Here, we further analyze the roles of 5-HT and another biogenic amine, dopamine (DA), on the crayfish response to stress. We show...
