Editing Laterality (section)

=== In mice ===
In mice (''Mus musculus''), laterality in paw usage has been shown to be a learned behavior (rather than inherited),<ref>{{Cite journal|last1=Biddle|first1=Fred G|last2=Eales|first2=Brenda A| year = 2006 |title=Hand-preference training in the mouse reveals key elements of its learning and memory process and resolves the phenotypic complexity in the behaviour|journal=Genome|language=en|volume=49|issue=6|pages=666–677|doi=10.1139/g06-026|pmid=16936846|issn=0831-2796}}</ref> due to which, in any population, half of the mice become left-handed while the other half becomes right-handed. The learning occurs by a gradual reinforcement of randomly occurring weak asymmetries in paw choice early in training, even when training in an unbiased world.<ref name=":0">{{Cite journal|last1=Ribeiro|first1=Andre S.|last2=Lloyd-Price|first2=Jason|last3=Eales|first3=Brenda A.|last4=Biddle|first4=Fred G.|year = 2010|title=Dynamic Agent-Based Model of Hand-Preference Behavior Patterns in the Mouse|journal=Adaptive Behavior|language=en|volume=18|issue=2|pages=116–131|doi=10.1177/1059712309339859|s2cid=10117297|issn=1059-7123}}</ref><ref name=":1">{{Cite journal|last1=Ribeiro|first1=Andre S.|last2=Eales|first2=Brenda A.|last3=Biddle|first3=Fred G.|year = 2011|title=Learning of paw preference in mice is strain dependent, gradual and based on short-term memory of previous reaches|journal=Animal Behaviour|language=en|volume=81|issue=1|pages=249–257|doi=10.1016/j.anbehav.2010.10.014|s2cid=26136740}}</ref> Meanwhile, reinforcement relies on short-term and long-term memory skills that are strain-dependent,<ref name=":0" /><ref name=":1" /> causing strains to differ in the degree of laterality of its individuals.
