Your Your Scientists & Meditation Discover Does To Gut Brain What
Microbial meddling has turned anxious mice bold and shy mice social. Rats inoculated with bacteria from depressed people develop signs of depression themselves. And small studies of people suggest that eating specific kinds of bacteria may change brain activity and ease anxiety.
Because gut bacteria can make the very chemicals that brain cells use to communicate, the idea makes a certain amount of sense. Though preliminary, such results suggest that the right bacteria in your gut could brighten mood and perhaps even combat pernicious mental disorders including anxiety and depression.
The wrong microbes, however, might lead in a darker direction. This perspective might sound a little too much like our minds are being controlled by our bacterial overlords. Microbes have been with us since even before we were humans. Human and bacterial cells evolved together, like a pair of entwined trees, growing and adapting into a mostly harmonious ecosystem. For starters, no one knows the exact ingredients for a healthy microbial community, and the recipe probably differs from person to person.
Nor is it clear how messages travel between microbes and brain, though scientists have some ideas. Escherichia coli and Campylobacter. For most residents, the illness was short-lived, about 10 days on average, says Dinan, who collaborates with Cryan at University College Cork.
But years later, scientists who had been following the health of Walkerton residents noticed something surprising. That spike raised suspicion that the infection had caused the depression. Other notorious bacteria have been tied to depression, such as those behind syphilis and the cattle-related brucellosis, and not just because ill people feel sad, Dinan says.
This possibility, though it raises troubling questions about free will, is certainly true for lab animals.
Mice born and raised without bacteria behave in all sorts of bizarre ways, exhibiting antisocial tendencies, memory troubles and recklessness, in some cases. Microbes in fruit flies can influence who mates with whom SN: By sheer numbers, human bodies are awash in bacteria.
A recent study estimates there are just as many bacterial cells as human cells in our bodies SN: Chemically, gut microbes and the brain actually speak the same language. The microbiome churns out the mood-influencing neurotransmitters serotonin, norepinephrine and dopamine.
Bacteria can also change how the central nervous system uses these chemicals. Signals between the gut and the brain may zip along the vagus nerve, a multilane highway that connects the two SN: Snip the nerve in mice and the bacteria no longer have an effect on behavior, a study found. And when the gut-to-brain messages change, problems can arise.
Wholesale microbe swaps can also influence behavior. The formerly carefree rodents soon began showing signs of depression and anxiety, forgoing a sweet water treat and showing more anxiety in a variety of tests.
Rats that got a microbiome from a person without depression showed no changes in behavior. Cryan and colleagues have found that the microbiomes of people with depression differ from those of people without depression, raising the possibility that a diseased microbiome could be to blame. The fecal-transplant results suggest that depression — and perhaps other mental disorders — are contagious, in a sense.
And a mental illness that could be caught from microbe swaps could pose problems. Fecal transplants have recently emerged as powerful ways to treat serious gut infections SN Online: Fecal donors ought to be screened for a history of mental illness along with other potentially communicable diseases, Dinan says.
The psychiatric characteristics of the donor should be taken into account as well, he says. A fecal transplant is an extreme microbiome overhaul. But there are hints that introducing just one or several bacterial species can also change the way the brain works.
One such example comes from Cryan, Dinan and colleagues. After taking a probiotic pill containing a bacterium called Bifidobacterium longum for a month, 22 healthy men reported feeling less stress than when they took a placebo. After taking the probiotic, the men also showed slight improvements on a test of visual memory, benefits that were reflected in the brain. EEG recordings revealed brain wave signatures that have been tied to memory skill, Cryan says.
The researchers had previously published similar effects in mice, but the new results move those findings into people. And whether there could be a benefit for people with heightened anxiety. Bacteria in an even more palatable form — yogurt — affected brain activity in response to upsetting scenes in one study. After eating a carefully concocted yogurt every morning and evening for a month, 12 healthy women showed a blunted brain reaction to pictures of angry or scared faces compared with 11 women who had eaten a yogurtlike food without bacteria.
Brain response was gauged by functional MRI, which measures changes in blood flow as a proxy for neural activity. Nonetheless, Tillisch says, the results raise the questions: Can they make you feel better if you feel bad? So far, the human studies have been very small. But coupled with the increasing number of animal studies, the results are hard to ignore, Tillisch says.
Our behavior can influence the microbiome right back. One of the easiest ways to do so is through food: Prebiotics nourish what are thought to be beneficial microbes, offering a simple way to cultivate the microbiome, and in turn, health. That a good diet is a gateway to good health is not a new idea, Cryan says. Take the old adage: Combating stress may be another way to change the microbiome, Tillisch and others suspect. Mouse studies have shown that stress, particularly early in life, can change microbial communities, and not in a good way.
She and her colleagues are testing a relaxation technique called mindfulness-based stress reduction to influence the microbiome. In people with gut pain and discomfort, the meditation-based practice reduced symptoms and changed their brains in clinically interesting ways, according to unpublished work. The researchers suspect that the microbiome was also altered by the meditation. They are testing that hypothesis now.
If the mind can affect the microbiome and the microbiome can affect the mind, it makes little sense to talk about who is in charge, Bordenstein says. An organism, Bordenstein and Theis argued, includes the microbes that live in and on it, a massive conglomerate of diverse parts called a holobiont.
This article appears in the April 2, , issue of Science News with the headline, "Microbes and the Mind. This hit of happiness is real. Even better, it lasts, because we're reconfiguring our capacity for happiness by rewiring our brains. Little happiness boosters like vacations are nice, but they've got no staying power. Researchers in the Netherlands discovered that the effects of a "very relaxing" vacation wear off after just two weeks. Meditation is so much cheaper than flying off to a beach somewhere, and there are many scientific studies showing it makes us happier in the long term.
You get to keep the glow going for as long as you want. We all have what psychologists call our "happiness set point," which is our individual capacity for joy. Mine might be high; someone else's might be low. But the good news for those who weren't born naturally happy is that this set point is not carved in stone.
It's been proven that we can grow new neurons, which means we can train our brains to go from mildly happy to wildly happy.
Or, as meditation teacher Amy Budden likes to say, "Meditation can trump environment and genes to help you hardwire happiness. Based on an excerpt from Unplug: Food has the power to create a happier and healthier world. Celebrity Nutritionist Kelly LeVeque will show you how.

Neuroscientist Sara Lazar's studies showed that meditation shrinks the amygdala, the part of the brain that controls anxiety and fear.
Less anxiety and fear translates to less stress. Less stress means more joy.
