Scaling of the corpus callosum in wild and domestic canids: Insights into the domesticated brain
Sign Up to like & getrecommendations! Published in 2018 at "Journal of Comparative Neurology"
DOI: 10.1002/cne.24486
Abstract: All domesticated mammals exhibit marked reductions in overall brain size, however, it is unknown whether the corpus callosum (CC), an integral white matter fiber pathway for interhemispheric cortical communication, is affected by domestication differentially or… read more here.

Brain size and behavioral specialization in the jataí stingless bee (Tetragonisca angustula)
Sign Up to like & getrecommendations! Published in 2022 at "Journal of Comparative Neurology"
DOI: 10.1002/cne.25333
Abstract: Social insects are instructive models for understanding the association between investment in brain size and behavioral variability because they show a relatively simple nervous system associated with a large set of complex behaviors. In the… read more here.

DOI: 10.1002/ece3.2717
Abstract: Abstract Evidence for phenotypic plasticity in brain size and the size of different brain parts is widespread, but experimental investigations into this effect remain scarce and are usually conducted using individuals from a single population.… read more here.

Using relative brain size as predictor variable: Serious pitfalls and solutions
Sign Up to like & getrecommendations! Published in 2022 at "Ecology and Evolution"
DOI: 10.1002/ece3.9273
Abstract: There is a long-standing interest in the effect of relative brain size on other life history variables in a comparative context. Historically, residuals have been used to calculate these effects, but more recently it has… read more here.

Allometry in the corpus callosum in neonates: Sexual dimorphism
Sign Up to like & getrecommendations! Published in 2022 at "Human Brain Mapping"
DOI: 10.1002/hbm.25977
Abstract: The corpus callosum (CC) is the largest fiber tract in the human brain, allowing interhemispheric communication by connecting homologous areas of the two cerebral hemispheres. In adults, CC size shows a robust allometric relationship with… read more here.

DOI: 10.1016/j.neuroimage.2017.04.029
Abstract: ABSTRACT Global structural brain connectivity has been reported to be sex‐dependent with women having increased interhemispheric connectivity (InterHc) and men having greater intrahemispheric connectivity (IntraHc). However, (a) smaller brains show greater InterHc, (b) larger brains… read more here.

DOI: 10.1016/j.neuroimage.2022.119118
Abstract: Studies examining cerebral asymmetries typically divide the L-R Measure (e.g., Left-Right Volume) by the L+R Measure to obtain an Asymmetry Index (AI). However, contrary to widespread belief, such a division fails to render the AI… read more here.

DOI: 10.1038/s41467-019-11757-x
Abstract: The ecological contexts that promote larger brains have received considerable attention, but those that result in smaller-than-expected brains have been largely overlooked. Here, we use a global sample of 2062 species to provide evidence that… read more here.

Does brain size affect mate choice? An experimental examination in pygmy halfbeaks

DOI: 10.1093/beheco/arab046
Abstract: Choosing a mate is one of the most important decisions in an animal’s lifetime. Female mate choice is often guided by the presence or intensity of male sexual ornaments, which must be integrated and compared… read more here.

DOI: 10.1093/gbe/evx028
Abstract: The adaptive significance of human brain evolution has been frequently studied through comparisons with other primates. However, the evolution of increased brain size is not restricted to the human lineage but is a general characteristic… read more here.

DOI: 10.1093/sysbio/syac075
Abstract: Increased brain size in humans and other primates is hypothesized to confer cognitive benefits but brings costs associated with growing and maintaining energetically expensive neural tissue. Previous studies have argued that changes in either diet… read more here.
