Brain-encysting trematodes (Euhaplorchis californiensis) decrease raphe serotonergic activity in California killifish (Fundulus parvipinnis)
Helland-Riise, Siri Helene; Vindas, Marco; Johansen, Ida Beitnes; Nadler, Lauren Elizabeth; Weinersmith, Kelly L.; Hechinger, Ryan F.; Øverli, Øyvind (Peer reviewed; Journal article, 2020)Modulation of brain serotonin (5-HT) signalling is associated with parasite-induced changes in host behaviour, potentially increasing parasite transmission to predatory final hosts. Such alterations could have substantial ... -
A brain‐infecting parasite impacts host metabolism both during exposure and after infection is established
Nadler, Lauren Elizabeth; Bengtson, Erik; Eliason, Erika J.; Helland-Riise, Siri Helene; Johansen, Ida Beitnes; Turner, Andrew; Øverli, Øyvind; Hechinger, Ryan F. (Peer reviewed; Journal article, 2020)1. Metabolic costs associated with parasites should not be limited to established infections. Even during initial exposure to questing and attacking parasites, hosts can enact behavioural and physiological responses that ... -
Depression-like state behavioural outputs may confer beneficial outcomes in risky environments
Vindas, Marco; Helland-Riise, Siri Helene; Nilsson, Göran Erik; Øverli, Øyvind (Peer reviewed; Journal article, 2019)Recent theories in evolutionary medicine have suggested that behavioural outputs associated with depression-like states (DLS) could be an adaptation to unpredictable and precarious situations. In animal models, DLS are ... -

Helland-Riise, Siri Helene; Nadler, Lauren Elizabeth; Vindas, Marco; Bengston, Erik; Turner, Andrew; Johansen, Ida Beitnes; Weinersmith, Kelly L.; Hechinger, Ryan F.; Øverli, Øyvind (Peer reviewed; Journal article, 2020)
