IBMT meditation found to boost brain connectivity

August 16th, 2010 in Medicine & Health / Research

Just 11 hours of learning a meditation technique induces positive structural changes in brain connectivity by boosting efficiency in a part of the brain that helps a person regulate behavior in accordance with their goals, researchers report.

Brain plasticity and fatherhood

Another look at how neuroplasticity works. Wonder if bonding behaviors in lovers induce similar, if perhaps less dramatic, changes?

Putting the brakes on impulsive behavior

This adds another piece to the puzzle. If you happen to have a brain that doesn't "turn down" dopamine well, then you'll get a more demanding "buzz" when it shoots up. This can make you impulsive, and more susceptible to thrill seeking.

What's not discussed in this research is whether - independent of genetic makeup - behavior can also cause this decrease in autoreceptors. By behavior, I'm thinking of gorging on superstimulating versions of natural reinforcers like junk food, porn, vibrators and so on.

Ayurvedic perspective on symptoms related to too much semen loss

I thought this was interesting because it describes symptoms so similar to those reported by heavy porn users. See Wiki: http://www.reuniting.info/withdrawal_symptoms_porn_recovery

Review of potential interactions between dopamine and oxytocin systems (and disorders)

This is for hard-core science-y types. Smiling

Below is a good review that discusses how social (and other) disorders may be related to the interaction between dopamine and oxytocin dysregulation. For us, it confirms the idea that the desire pathway, when dysregulated, can mess with social bonds.

Another Helen Fisher Love study

There's a recent study that I think's related to the other in love brain studies that Helen Fisher did:

More food for thought.

Sex at Dawn

I'm reading a new book, Sex at Dawn, and there's an article in 3 + parts at Psychology Today, which is series of questions and answers from the author, and a bit of a 'contest' to win a copy of the book by posing a question of the author. http://www.psychologytoday.com/blog/sex-dawn

There's an interview, of sorts (similar answers) at Salon http://www.salon.com/books/feature/2010/06/27/sex_at_dawn_interview/inde...

On the other hand - there's this link, http://www.nerve.com/content/a-ladies-man-and-shameless that the author linked to in the FAQ.

Either way, food for thought.

Brain Study Highlights Role of Dopamine in Impulsive Behavior

This research is important because it hints at the role of behavior in dysregulating dopamine. Certain cues cause impulsivity, due to dopamine release.
