Simple Summary We used to think of brains as symmetrical, functioning in the same way on
the left and right sides, but we now know that this is not so. From the small brains of insects …

Why do the left and right sides of the brain have different functions? Having a lateralized
brain, in which each hemisphere processes sensory inputs differently and carries out …

Although the left and right hemispheres of our brains develop with a high degree of
symmetry at both the anatomical and functional levels, it has become clear that subtle …

Elevated carbon dioxide (CO2) has recently been shown to affect chemosensory and
auditory behaviour, and activity levels of larval reef fishes, increasing their risk of predation …

Background Humans and non-human animals share an approximate non-verbal system for
representing and comparing numerosities that has no upper limit and for which accuracy is …

While associations between number and space, in the form of a spatially oriented numerical
representation, have been extensively reported in human adults, the origins of this …

Genetic and environmental factors control morphological and functional differences between
the two sides of the nervous system. Neural asymmetries are proposed to have important …

Individual differences in cognitive abilities have been thoroughly investigated in humans
and to a lesser extent in other mammals. Despite the growing interest in studying cognition …

Humans interact with fishes in many contexts including aquaculture, scientific study and
companion animals. In all of these contexts, fish welfare can be compromised through …

It is widely acknowledged that the left and right hemispheres of human brains display both
anatomical and functional asymmetries. For more than a century, brain and behavioral …
