Space availability influence laterality in donkeys (Equus asinus)
Cerebral lateralization is the portioning of the cognitive functions between the two cerebral hemispheres. Several factors, like embryological manipulations, light exposure, health conditions, sex and age can influence the left–right brain asymmetries and contribute to increasing the variability in the strength and direction of laterality within most species. We investigated the influence of an environmental […]
Structured bimanual actions and hand transfers reveal population-level right-handedness in captive gorillas
There is a common prevailing perception that humans possess a species-unique population-level right-hand bias that has evolutionary links with language. New theories suggest that an early evolutionary division of cognitive function gave rise to a left-hemisphere bias for behaviours underpinned by structured sequences of actions. However, studies of great ape handedness have generated inconsistent results […]
