The manner with which genes and hormones interact in the brain alters parenting behavior in mice, a recent study has revealed.
Even though the research was conducted on mice, the sex hormones portray similar effects in mammals. Many of the genes found in mice are also found in humans.
"Testosterone and estrogen control sexually dimorphic behaviors in vertebrate species, we've known that for a long time that they control behaviors at a very large-scale level. What we've discovered are [some of] the gene networks that are regulated by these sex hormones," study researcher Nirao Shah, of the University of California, San Francisco said.
