Scientists discover how fathers improve brain development of children

Story from the Wall Street Journal. (H/T Andrew)

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.

Understanding the effect of sex on your brain chemistry

2 Comments

This article was sent to me by my friend Andrew. It’s by Marcia Segelstein.

Marcia is trying to make the same point about sex that Miriam Grossmann made in her book “Unprotected”. The point is that although bureaucrats and educrats love to tell people about the riskiness of behaviors like smoking and obesity, they don’t tell people the truth about the dangers of casual sex, because they don’t want to antagonize special interest groups like feminists and gay activists.

In the article, Marcia talks about the mental effects of casual sex. She talks about dopamine first, but the one I want to tell you about is called oxytocin. It is very important that you parents of young ladies understand this and present this evidence to your daughters. (The male version of this phenomenon is also explained in the article, it’s called vasopressin).

Excerpt:

Oxytocin is another important brain chemical we are now learning more about.  Oxytocin helps females, in particular, bond with other people.  When a new mother breastfeeds her infant, for example, oxytocin floods her brain.  The effect is powerful.  She feels a strong desire to be with her baby, and is willing to suffer the sleepless nights and inconveniences that come with having a baby.

Oxytocin also helps females bond with men.  When a woman and man touch each other in a loving way, oxytocin is released in her brain.  It makes her want more of that loving touch, and she begins to feel a bond with her partner.  Sexual intercourse leads to the release of even more oxytocin, a desire to repeat the contact, and even stronger bonding.  But, like dopamine, oxytocin is values-neutral.  It’s a chemical reaction, or, as the authors write: “[I]t is an involuntary process that cannot distinguish between a one-night stand and a lifelong soul mate.  Oxytocin can cause a woman to bond to a man even during what was expected to be a short-term sexual relationship.”  So when that short-term relationship ends, the emotional fallout can be devastating, thanks to oxytocin.

Another significant finding about oxytocin is that it produces feelings of trust.  That can be good or bad, depending on the situation.  “While the hormonal effect of oxytocin is ideal for marriage, it can cause problems for the unmarried woman or girl who is approached by a man desiring sex….[T]he warning is that a woman’s brain can cause her to be blindsided by a bad relationship that she thought was good because of the physical contact and the oxytocin response it generates.”

This is why Dr. Jennifer Roback Morse says that the only smart sex is married sex. Otherwise you are just coarsening your own self. Neil Simpson calls this the duct tape theory of sex. He explains why sex is like duct tape here. Don’t order your children around – give them the data so they understand the why of chastity.
