Gay dads' brains show activity akin to both parents': study

By Sharon Begley NEW YORK (Reuters) - Having a baby alters new mothers' brain activity, researchers have found, and a new study adds the first evidence of such changes in the brains of gay men raising children they adopted through surrogacy. The men's pattern of brain activity resembles that of both new mothers and new fathers in the study. The current study, published in Proceedings of the National Academy of Sciences, was conducted in Israel, and builds on work by neuropsychologist Ruth Feldman of Bar-Ilan University and others, who showed that the brains of new mothers become hyper-reactive to their child's cries and other emotional cues. They then measured the parents' brain activity while watching the videos in an MRI tube, and again (to establish a baseline) while watching videos that their kids did not star in.
