Three days later, with the help of Wolfgang Liedtke from Duke University, an area at the base of the brain called the hypothalamus was analyzed for genetic patterns.

''What was surprising was when the data in the genetic pattern was examined, it was clear that the genes that the salt appetite had activated were the same pattern of genes that were altered in addiction to cocaine or to opium,''  Denton, of Melbourne's Howard Florey Institute, said.

A separate group of mice were denied salt over the same period. But unlike the first group, they were allowed ''their fix'' of saline solution. Analysis of their brains after drinking the salt showed a difference in the genetic expression in that part of the brain.
