Editing Aggression (section)

===Pheromones===
In many animals, aggression can be linked to [[pheromone]]s released between [[conspecifics]]. In mice, [[major urinary proteins]] (Mups) have been demonstrated to promote innate aggressive behavior in males,<ref name="BBCreport">{{cite news |title=Aggression protein found in mice |work=[[BBC News]] |date=5 December 2007 |url=http://news.bbc.co.uk/2/hi/science/nature/7129176.stm |access-date=26 September 2009}}</ref><ref name=Chamero1>{{cite journal |author=Chamero P |title=Identification of protein pheromones that promote aggressive behaviour |journal=Nature |volume=450 |issue=7171 |pages=899–902 |date=December 2007 |pmid=18064011 |doi=10.1038/nature05997 |author2=Marton TF |author3=Logan DW |display-authors=3 |last4=Flanagan |first4=Kelly |last5=Cruz |first5=Jason R. |last6=Saghatelian |first6=Alan |last7=Cravatt |first7=Benjamin F. |last8=Stowers |first8=Lisa|bibcode=2007Natur.450..899C |s2cid=4398766 }}</ref> and can be mediated by neuromodulatory systems.<ref>{{cite journal |doi=10.1523/JNEUROSCI.0099-15.2015 |pmid=26224860 |pmc=4518052 |title=Differential Muscarinic Modulation in the Olfactory Bulb |journal=Journal of Neuroscience |volume=35 |issue=30 |pages=10773–85 |year=2015 |last1=Smith |first1=R.
