It has been hypothesized that cerebral lateralization can significantly enhance cognition and
that this was one of the primary selective forces shaping its wide-spread evolution amongst …

A large number of studies showed that fish possess numerical abilities similar to those
reported in mammals and birds. However, inter-individual differences in numerical …

Cerebral laterality, via hemispheric specialisation, has been evidenced across the animal
kingdom and linked to cognitive performance in a number of species. Previously it has been …

Laboratory and field studies have documented better cognitive performance associated with
marked hemispheric specialization in organisms as diverse as chimpanzees, domestic …

Cerebral lateralization refers to the division of information processing in either hemisphere
of the brain and is a ubiquitous trait among vertebrates and invertebrates. Given its …

Mosaic brain evolution, the change in the size of separate brain regions in response to
selection on cognitive performance, is an important idea in the field of cognitive evolution …

Determining how variation in brain morphology affects cognitive abilities is important to
understand inter-individual variation in cognition and, ultimately, cognitive evolution. Yet …

Cerebral lateralization has been suggested to convey a selective advantage to individuals
by enhancing their cognitive abilities. Few, however, have explicitly compared the cognitive …

In this review, we discuss evidence showing that birds (Gallus gallus and Nucifraga
columbiana) represent numerical magnitudes as being oriented from left to right. Subjects …

Lateralization of brain and behavior in both humans and nonhuman animals is a topic that
has fascinated neuroscientists since its initial discovery in the mid of the nineteenth century …
