Brain imaging investigations have found further evidence for the theory. Support for the idea of a high visual sensitivity to snakes has been proven in primate neural activity in response to snake threats.<ref>{{cite journal|last1=Van Le|first1=Quan|last2=Isbell|first2=Lynne A.|last3=Matsumoto|first3=Jumpei|last4=Nguyen|first4=Minh|last5=Hori|first5=Etsuro|last6=Maior|first6=Rafael S.|last7=Tomaz|first7=Carlos|last8=Tran|first8=Anh Hai|last9=Ono|first9=Taketoshi|last10=Nishijo|first10=Hisao|title=Pulvinar neurons reveal neurobiological evidence of past selection for rapid detection of snakes|journal=Proceedings of the National Academy of Sciences of the United States of America|date=19 November 2013|volume=110|issue=47|pages=19000–19005|doi=10.1073/pnas.1312648110|pmid=24167268|issn=1091-6490|pmc=3839741}}</ref> Non-invasive electroencefalogramelectroencephalogram ([[EEG]]) studies have found an enhanced visual brain activity in response to images of snakes in humans.<ref>{{cite journal|last1=Van Strien|first1=J.
