Bizarrely, rats infected with the brain parasite Toxoplasma gondii approach the cat odors they typically avoid. Since the protozoan Toxoplasma requires the cat to sexually reproduce, this change in host behavior is thought to be a remarkable example of a parasite manipulating a mammalian host for its own benefit. Toxoplasma does not influence host response to non-feline predator odor nor does it alter behavior on olfactory, social, fear or anxiety tests, arguing for specific manipulation in the processing of cat odor. We report that Toxoplasma infection alters neural activity in limbic brain areas necessary for innate defensive behavior in response to cat odor. Moreover, Toxoplasma increases activity in nearby limbic regions of sexual attraction when the rat is exposed to cat urine, compelling evidence that Toxoplasma overwhelms the innate fear response by causing, in its stead, a type of sexual attraction to the normally aversive cat odor.", "link"=>"http://www.mendeley.com/research/predator-cat-odors-activate-sexual-arousal-pathways-brains-toxoplasma-gondii-infected-rats", "reader_count"=>331, "reader_count_by_academic_status"=>{"Unspecified"=>10, "Professor > Associate Professor"=>13, "Researcher"=>61, "Student > Doctoral Student"=>19, "Student > Ph.

In rat infected with the brain parasite Toxoplasma gondii avoidance responses to cat odors are abolished and rats tend to approach places marked with odors of their predator. Interestingly Toxoplasma requires the cat to sexually reproduce. In the present article, the authors investigated the brain activity of infected rats. They found that “Toxoplasma infection alters neural activity in limbic brain areas necessary for innate defensive behavior in response to cat odor”. Furthermore “Toxoplasma increases activity in nearby limbic regions of sexual attraction when the rat is exposed to cat urine”. These amazing data clarify how a parasite can, for reproductive needs and in an evolutionary adaptive manner, manipulate the behaviour of its host through an action on its brain. This switch of rat behaviour from innate fear of cat odor to attraction is quite remarkable and should interest a broad readership", "isRemoved"=>false, "created"=>"2011-09-01T13:33:10Z", "lastModified"=>"2011-09-01T13:33:10Z", "creator"=>{"userId"=>"164411"}, "highlightedText"=>"", "competingInterestStatement"=>{"creatorWasPrompted"=>true, "hasCompetingInterests"=>false}, "parentArticle"=>{"doi"=>"info:doi/10.1371/journal.pone.0023277", "state"=>"published", "journals"=>{"PLoSONE"=>{"journalKey"=>"PLoSONE", "eIssn"=>"1932-6203", "title"=>"PLOS ONE"}}}, "replyTreeSize"=>0, "mostRecentActivity"=>"2011-09-01T13:33:10Z", "replies"=>[]}

Bizarrely, rats infected with the brain parasite <em>Toxoplasma gondii</em> approach the cat odors they typically avoid. Since the protozoan <em>Toxoplasma</em> requires the cat to sexually reproduce, this change in host behavior is thought to be a remarkable example of a parasite manipulating a mammalian host for its own benefit. <em>Toxoplasma</em> does not influence host response to non-feline predator odor nor does it alter behavior on olfactory, social, fear or anxiety tests, arguing for specific manipulation in the processing of cat odor. We report that <em>Toxoplasma</em> infection alters neural activity in limbic brain areas necessary for innate defensive behavior in response to cat odor. Moreover, <em>Toxoplasma</em> increases activity in nearby limbic regions of sexual attraction when the rat is exposed to cat urine, compelling evidence that <em>Toxoplasma</em> overwhelms the innate fear response by causing, in its stead, a type of sexual attraction to the normally aversive cat odor.</p> </div>", "links"=>[], "tags"=>["odors", "activate", "arousal", "pathways", "brains", "infected", "rats"], "article_id"=>134184, "categories"=>["Neuroscience", "Mental Health", "Microbiology", "Evolutionary Biology"], "users"=>["Patrick K.
