[[File:Allo-endo.tif|thumb|right|[[Endocast]] (cast of the brain cavity) of ''Allosaurus'']]
The brain of ''Allosaurus'', as interpreted from spiral [[CT scan]]ning of an [[Endocranial cast|endocast]], was more consistent with [[crocodilia]]n brains than those of the other living [[archosaur]]s, birds. The structure of the [[Vestibular system|vestibular apparatus]] indicates that the skull was held nearly horizontal, as opposed to strongly tipped up or down. The structure of the [[inner ear]] was like that of a crocodilian, indicating that ''Allosaurus'' was more adapted to hear lower frequencies and would have had difficulty hearing subtle sounds.<ref>{{Cite journal |last=Rogers |first=Scott W. |date=May 2005 |title=Reconstructing the behaviors of extinct species: An excursion into comparative paleoneurology |url=https://onlinelibrary.wiley.com/doi/10.1002/ajmg.a.30538 |journal=American Journal of Medical Genetics Part A |language=en |volume=134A |issue=4 |pages=349–356 |doi=10.1002/ajmg.a.30538 |pmid=15759265 |issn=1552-4825 |archive-date=January 17, 2024 |access-date=January 17, 2024 |archive-url=https://web.archive.org/web/20240117170649/https://onlinelibrary.wiley.com/doi/10.1002/ajmg.a.30538 |url-status=live |url-access=subscription }}</ref> The [[olfactory bulb]]s were large and well suited for detecting odors,<ref name=SWR99/> but were typical for an animal of its size.<ref>{{cite journal | pmc=2660930 | date=2008 | last1=Zelenitsky | first1=D.
