By targeting receptors of a hormone called vasopressin, it is hoped that the investigational drug will prove effective in controlling the abnormal contractions that cause painful periods.
Even after steroids were discontinued, their anterior hypothalamus, known to regulate aggression, continued to pump out more of a neurotransmitter called vasopressin, which induces aggression.
This same gene has also been linked in a different study to dictatorial behavior, and the hormone, called vasopressin, made by this gene has been found to be plentiful in voles that mate for life.
By altering a single gene that affects a brain chemical called vasopressin, researchers at Emory University in Atlanta turned philandering mice into devoted mates.
