Children who are suffering from depression experience brain changes similar to the changes observed in depressed adults, new research published in The Journal of the American Academy of Child & Adolescent Psychiatry has found. The New York Times reports:

The children underwent M.R.I. brain scans while viewing pictures of happy, sad, fearful or neutral faces. The researchers found that right amygdala and right thalamus activity was significantly greater in the depressed children than in the others, a finding that has also been observed in depressed adolescents and adults.
“We found something in the brain that is aligned with the idea of neurobiological models of depression — which parts of the brain are involved and how they interact,” said the lead author, Michael S. Gaffrey, an assistant professor in the department of psychiatry at Washington University in St. Louis. “We can begin to use this information in conjunction with other information — symptoms, other biological markers — to identify and eventually prevent and treat this disorder.”

The live birth of a child is a little bit less of a scientific mystery, thanks to a new video that was taken inside an open MRI machine. From MSNBC.com, which has posted part of the video:
The baby was born in November, 2010 at Charité University Hospital in Berlin, Germany; photos of the MRI images were published earlier, but the video was just published this month in the American Journal of Obstetrics and Gynocology.
The video shows the final 45 minutes of labor. Magnetic resonance imaging (MRI) is safe for pregnant women and babies; the main hazard was the loud noise the machine makes. Mom wore headphones to protect her hearing, and the baby’s ears were protected by amniotic fluid — they turned the MRI machine off when the baby’s head started to come out.
To this day, many aspects of birth remain a medical mystery — one that researchers are hoping to unravel.
“The main reasons for the research are to answer the question of why a birth may stall and to visually capture the birthing process and any complications,” Dr. Christian Bamberg, who led the research team, told Reuters in 2010. “The images are spectacular. They show which movements the fetus makes in the birth canal, how its bones move and how its head changes shape during birth.”
Mom and baby were healthy, and they both left the hospital two days after the birth.
