It is
well known lipopolysaccharides (LPS) is produced by infected bacteria and triggers
several acute phase responses after infection. Some reports show that rodents
can acquire aversion to the taste stimulus paired with LPS. However,
the brain mechanisms in the conditioned taste aversion (CTA) with LPS and in its
retrieval remain obscure. To elucidate
the brain mechanism in the retrieval of CTA with LPS (LPS-CTA), we
tried to visualize the brain activities by using the manganese enhanced MRI (MEMRI). In consequence, we found the activation of DMH in relation with the regulation of body temperature in the retrieval of LPS-CTA cause body.
