Associative Mechanisms Allow for SocialLearning and Cultural Transmission of StringPulling in an Insect
Alem, Sylvain; Perry, Clint J; Zhu, Xingfu; Loukola, Olli; Ingraham, Thomas; Søvik, Eirik; Chittka, Lars (Journal article, 2016)Social insects make elaborate use of simple mechanisms to achieve seemingly complex behavior and may thus provide a unique resource to discover the basic cognitive elements required for culture, i.e., group-specific behaviors ... -
Cocaine Directly Impairs Memory Extinction and Alters Brain DNA Methylation Dynamics in Honey Bees
Søvik, Eirik; Berthier, Pauline; Klare, William P; Helliwell, Paul; Buckle, Edwina L S; Plath, Jenny A; Barron, Andrew B; Maleszka, Ryszard (Peer reviewed; Journal article, 2018)Drug addiction is a chronic relapsing behavioral disorder. The high relapse rate has often been attributed to the perseverance of drug-associated memories due to high incentive salience of stimuli learnt under the influence ... -
Comment on “Food wanting is mediated by transient activation of dopaminergic signaling in the honey bee brain”
Barron, Andrew B; Fahrbach, Susan E.; Mercer, Alison R; Mesce, Karen A; Schulz, David J; Smith, Brian H.; Søvik, Eirik (Peer reviewed; Journal article, 2023) -
Drosophila divalent metal ion transporter Malvolio is required in dopaminergic neurons for feeding decisions
Søvik, Eirik; LaMora, Angela; Seehra, Gurpreet; Barron, Andrew B; Duncan, Jennifer G; Ben-Shahar, Yehuda (Peer reviewed; Journal article, 2017)Members of the natural resistance-associated macrophage protein (NRAMP) family are evolutionarily conserved metal ion transporters that play an essential role in regulating intracellular divalent cation homeostasis in both ... -
The evolutionary history of consciousness
Søvik, Eirik; Perry, Clint J (Journal article, 2016)Klein & Barron argue that insects are capable of subjective experience, i.e., sentience. Whereas we mostly agree with the conclusion of their arguments, we think there is an even more important message to be learned from ... -
Large-scale transcriptome changes in the process of long-term visual memory formation in the bumblebee, Bombus terrestris
Li, Li; Su, Songkun; Perry, Clint J; Elphick, Maurice R; Chittka, Lars; Søvik, Eirik (Peer reviewed; Journal article, 2018)Many genes have been implicated in mechanisms of long-term memory formation, but there is still much to be learnt about how the genome dynamically responds, transcriptionally, during memory formation. In this study, we ... -
Learning, gustatory responsiveness and tyramine differences across nurse and forager honeybees
Scheiner, Ricarda; Reim, Tina; Søvik, Eirik; Entler, Brian V; Barron, Andrew B; Thamm, Markus (Peer reviewed; Journal article, 2017)Honeybees are well known for their complex division of labor. Each bee sequentially performs a series of social tasks during its life. The changes in social task performance are linked to gross differences in behavior and ...
