Mark Fenske: Between the heavy mallet and the paving stone, my misplaced finger didn’t stand a chance. But it wasn’t the sight of the bloody, smashed-apart fingernail or split-open fingertip that first made clear my mistake. It was the pain. That searing, body-tensing, tears-in-the-eyes pain.

The basic function of pain is to interrupt whatever else is going on and draw our attention to the fact that something is wrong, that the body is facing or has already suffered some kind of damage. Sensory nerves, called nociceptors (i.e. danger receptors) detect elements capable of body-tissue damage, such as pressure or extreme heat. The nerves’…

Many interactions these days have a kind of bumper-car quality to them. At work, at home, on the telephone, via email: we sort of bounce off of each other while we exchange information, smile or frown, and move on. How often do we actually take the extra few seconds to get a sense of what’s inside other people – especially their good qualities?

In fact, because of what scientists call the brain’s “negativity bias” (you could see my talk at Google for more on this), we’re most likely to notice the bad qualities in others rather than the good ones: the things that worry or annoy us, or …

Tone matters.

I remember times I felt frazzled or aggravated and then said something with an edge to it that just wasn’t necessary or useful. Sometimes it was the words themselves: such as absolutes like “never” or always,” or over-the-top phrases like “you’re such a flake” or “that was stupid.” More often it was the intonation in my voice, a harsh vibe or look, interrupting, or a certain intensity in my body. However I did it, the people on the receiving end usually looked like they’d just sucked a lemon. This is what I mean by tart tone.

People are more sensitive to tone than to the explicit content …

Things come at us with so much urgency and demand these days. Phones ring, texts buzz, emails pile up, new balls have to be juggled, work days lengthen and move into evenings and weekends, traffic gets denser, financial demands feel like a knife at the neck, ads and news clamor for attention, push push push PUSH.

On top of these external pressures, we deal with internal ones as well. These include all the inner “shoulds,” “musts,” and “have-tos,” like: “I gotta get this done today or my boss’ll get mad.” Or: “I must not look bad.” Or: “I can’t leave the house with dishes in …

Alex Knapp, Forbes: Dr. Kerr received her BA in American Studies from Amherst College and her PhD in History and Social Theory from the Johns Hopkins University, but in 2006 received a K Award from the National Institutes of Health to be retrained as a neuroscientist. Since then, her research primarily focused on the effects of meditation the brain.

Tell me about your background. What got you interested in studying meditation?

The route that I took on the way towards my study looking at the effects of meditation training on alpha rhythms in somatosensory cortex has been…

Studies have shown that ­meditating regularly can help relieve chronic pain, but the neural mechanisms ­underlying the relief were unclear. Now, ­researchers from MIT, Harvard, and Massachusetts General ­Hospital have found a possible explanation.

In a recent study published in the journal Brain Research Bulletin, the researchers found that people trained to meditate over an eight-week period were better able to control a specific type of brain waves, called alpha rhythms.

“These activity patterns are thought to minimize distractions, to diminish the likelihood stimuli will grab your attention,” says Christopher Moore, PhD…

We evolved to be afraid.

The ancient ancestors that were casual and blithely hopeful, underestimating the risks around them – predators, loss of food, aggression from others of their kind – did not pass on their genes. But the ones that were nervous were very successful – and we are their great-grandchildren, sitting atop the food chain.

Consequently, multiple hair-trigger systems in your brain continually scan for threats. At the least whiff of danger – which these days comes mainly in the form of social hazards like indifference, criticism, rejection, or disrespect – alarm bells start ringing. See a frown across a dinner table, hear a cold tone from a supervisor, …

Study shows practice may have potential to change brain’s physical structure

Two years ago, researchers at UCLA found that specific regions in the brains of long-term meditators were larger and had more gray matter than the brains of individuals in a control group. This suggested that meditation may indeed be good for all of us since, alas, our brains shrink naturally with age.

Now, a follow-up study suggests that people who meditate also have stronger connections between brain regions and show less age-related brain atrophy. Having stronger connections influences the ability to rapidly relay electrical signals in the brain. And significantly, these effects are evident throughout the entire brain, not just …

To simplify a complex process, your brain evolved in three stages:

• Reptile – Brainstem, focused on avoiding harm
• Mammal – Limbic system, focused on approaching rewards
• Primate – Cortex, focused on attaching to “us”

This post is about weaving the sense of being included and loved into the primate cerebral cortex.

In ancient times, membership in a band was critical to survival: exile was a death sentence in the Serengeti. Today, feeling understood, valued, and cherished – whether as a child or an adult, and with regard to another person or to a group – may not be a life and death matter (though studies do show that survival rates for cancer …

Dan Harris & Erin Brady (ABC News): A quiet explosion of new research indicating that meditation can physically change the brain in astonishing ways has started to push into mainstream.

Several studies suggest that these changes through meditation can make you happier, less stressed — even nicer to other people. It can help you control your eating habits and even reduce chronic pain, all the while without taking prescription medication.

Meditation is an intimate and intense exercise that can be done solo or in a group, and one study showed that 20 million Americans say they practice meditation. It has been used to help treat addictions, to clear psoriasis and even to treat men with impotence.
