Comparative studies on brain asymmetry date back to the 19th century but then largely
disappeared due to the assumption that lateralization is uniquely human. Since the …

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 …

Our goal in this chapter is to provide a concise introduction to the study of left–right
asymmetries in brain and behavior from a comparative perspective. We consider evidence …

Lateralization, ie, the different functional roles played by the left and right sides of the brain,
is expressed in two main ways:(1) in single individuals, regardless of a common direction …

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 …

Mice and rats are among the most common animal model species in both basic and clinical
neuroscience. Despite their ubiquity as model species, many clinically relevant brain …

Lateralization is widespread throughout the animal kingdom [1–7] and can increase task
efficiency via shortening reaction times and saving on neural tissue [8–16]. However …

The study of brain and behavioral lateralization in so-called “lower vertebrates”(fish,
amphibians, and reptiles) has received increasing attention in the last years, in an attempt to …

Behavioral lateralization is widespread across the animals, being found in numerous
vertebrate species as well as in species from across many invertebrate phyla. Numerous …
