Scientists discover how fathers improve brain development of children

Excerpt:

Dr. Braun’s group found that at 21 days, the fatherless animals had less dense dendritic spines compared to animals raised by both parents, though they “caught up” by day 90. However, the length of some types of dendrites was significantly shorter in some parts of the brain, even in adulthood, in fatherless animals.

“It just shows that parents are leaving footprints on the brain of their kids,” says Dr. Braun, 54 years old.

The neuronal differences were observed in a part of the brain called the amygdala, which is related to emotional responses and fear, and the orbitofrontal cortex, or OFC, the brain’s decision-making center.

[…]The balance between these two brain parts is critical to normal emotional and cognitive functioning, according to Dr. Braun. If the OFC isn’t active, the amygdala “goes crazy, like a horse without a rider,” she says. In the case of the fatherless pups, there were fewer dendritic spines in the OFC, while the dendrite trees in the amygdala grew more and longer branches.

A preliminary analysis of the degus’ behavior showed that fatherless animals seemed to have a lack of impulse control, Dr. Braun says. And, when they played with siblings, they engaged in more play-fighting or aggressive behavior.

In a separate study in Dr. Braun’s lab conducted by post-doctoral researcher Joerg Bock, degu pups were removed from their caregivers for one hour a day. Just this small amount of stress leads the pups to exhibit more hyperactive behaviors and less focused attention, compared to those who aren’t separated, Dr. Braun says. They also exhibit changes in their brain.

The basic wiring between the brain regions in the degus is the same as in humans, and the nerve cells are identical in their function. “So on that level we can assume that what happens in the animal’s brain when it’s raised in an impoverished environment … should be very similar to what happens in our children’s brain,” Dr. Braun says.

New Scientist article shows why fathers are necessary for children’s well-being

Here’s a story from the New Scientist. (H/T Jennifer Roback Morse)

First let’s re-cap the old stuff:

Previous studies have hinted at the importance of fathers in child-rearing. Some have shown that girls reach puberty younger, become sexually active earlier and are more likely to get pregnant in their teens if their father was absent when they were young. Others have suggested that the sons of absent fathers display lower intimacy and self-esteem.

Now let’s get the new stuff:

Cells in pups deprived of fathers had a blunted response to oxytocin – the “cuddle chemical”, which is normally released during social interactions and pair bonding. They also had an increased response to NMDA, which is involved in memory.

The fatherless mice were also less interested in engaging with other mice. “Usually if you put two animals in the same cage they investigate and touch each other, but when we put two animals deprived of a father together they ignored each other,” says Gobbi. Her colleague Francis Bambico presented the work at the World Congress of Biological Psychiatry in Paris, France, in early July.

But according to this Telegraph article, it doesn’t seem as though research impacts public policy. (H/T Andrew)

Excerpt:

Women who undergo fertility treatment and their same-sex partners are now both allowed to register as parents on their baby’s birth certificates.

The move has been criticised for damaging the traditional notion of a family, which many people say is necessary for a healthy upbringing.

But ministers insist it is a step forward for equal rights.

Lord Brett, the Home Office Minister, said: “This positive change means that for the first time female couples who have a child using fertility treatment have the same rights as their heterosexual counterparts to be shown as parents in the birth registration.

“It is vital that we afford equality wherever we can in society, especially as family circumstances continue to change. This is an important step forward in that process.”

There are powerful special interest groups on the left whose whole purpose is to demonize fathers and destroy marriage. They want children to be raised by the state, (i.e. – by those who run the secular government). They think that government programs taught by strangers and designed by experts well-versed in all the isms of the left, are better for children than their biological parents.
