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 …

Social play has been described in many animals. However, much of this social behaviour
among birds, particularly in adults, is still relatively unexplored in terms of the environmental …

The human brain is generally anatomically symmetrical, boasting mirror-like brain regions in
the left and right hemispheres. Despite this symmetry, fine-scale structural asymmetries are …

The evolution of human right-handedness has been intensively debated for decades.
Manual lateralization patterns in non-human primates have the potential to elucidate …

Until the 1990s, the notion of brain lateralization—the division of labor between the two
hemispheres—and its more visible behavioral manifestation, handedness, remained fiercely …

Hemispheric asymmetries differ considerably across species, but the neurophysiological
base of this variation is unclear. It has been suggested that hemispheric asymmetries …

Cerebral lateralization, which is often reflected in an individual's behavioral laterality (eg,
handedness and footedness), may bring animals certain benefits such as enhanced …

ABSTRACT The New Caledonian crow (Corvus moneduloides) is known for displaying a
unique set of tool-related behaviours, with the bird's bill acting as an individually consistently …

Asymmetry is an inherent characteristic of brain organization in both humans and other
vertebrate species, and is evident at the behavioral, neurophysiological, and structural …
