Gut Bacteria And The Brain: Are We Controlled By Microbes?

Although the interaction between our brain and gut has been studied for years, its complexities run deeper than initially thought. It seems that our minds are, in some part, controlled by the bacteria in our bowels.

The gut has defenses against pathogens, but, at the same time, it encourages the survival and growth of "healthy" gut bacteria.

The vast majority of these single-celled visitors are based in the colon, where no less than 1 trillion reside in each gram of intestinal content.

Estimating the number of bacterial guests in our gut is challenging; to date, the best guess is that 40 trillion bacteria call our intestines home - partially dependent on the size of your last bowel movement (poop's major ingredient is bacteria).

What It Means When You Dream About Being Naked In Public

You’re at the office and everything is normal... Until you get up during a meeting to give a presentation and you realize you are totally naked. 

It’s a dream many people have had in some iteration. But experts still aren’t entirely sure what it means.

Most psychologists agree it probably doesn’t represent a literal desire to be naked in public, but more likely is related to being embarrassed about something about yourself that other people don’t know about you.

Other psychologists have suggested this type of dream comes from harboring feels of guilt or inferiority ― or may be triggered by feeling neglected or deprived of attention in the past.

Of course some people think it means nothing at all. But neuroscientists and psychologists are convinced that, apart from meaning, dreams serve an important role in maintaining our mental and emotional health.

Decades of research suggest that dreams help us make memories, solve the problems we struggle with in our waking hours and process emotions ― even unpleasant ones where you accidentally expose yourself to everyone at work.

Language Learning Boosts Brain Plasticity And Ability To Code New Information

By studying brain electrical activity of volunteers, researchers found that language acquisition enhances brain plasticity and capacity for learning. In particular, they note that early language learning plays a significant role in the rapid formation of memory circuits for coding new information.

In a paper published in the journal Scientific Reports, researchers from the Higher School of Economics (HSE), in Moscow, Russia, and the University of Helsinki, in Finland, describe how they used EEG (electroencephalography) to probe the brain mechanisms involved in language learning in human volunteers.

Previous research has established that understanding the brain mechanisms involved in acquiring language helps enormously in the diagnosis and treatment of people with impaired speech following accidents, strokes, and other related conditions.

It’s ‘Digital Heroin’: How Screens Turn Kids into Psychotic Junkies

Susan bought her 6-year-old son John an iPad when he was in first grade. “I thought, ‘Why not let him get a jump on things?’ ” she told me during a therapy session. John’s school had begun using the devices with younger and younger grades — and his technology teacher had raved about their educational benefits — so Susan wanted to do what was best for her sandy-haired boy who loved reading and playing baseball.

She started letting John play different educational games on his iPad. Eventually, he discovered Minecraft, which the technology teacher assured her was “just like electronic Lego.” Remembering how much fun she had as a child building and playing with the interlocking plastic blocks, Susan let her son Minecraft his afternoons away.

At first, Susan was quite pleased. John seemed engaged in creative play as he explored the cube-world of the game. She did notice that the game wasn’t quite like the Legos that she remembered — after all, she didn’t have to kill animals and find rare minerals to survive and get to the next level with her beloved old game. But John did seem to really like playing and the school even had a Minecraft club, so how bad could it be?

Chronic Fatigue Syndrome: Could Altered Gut Bacteria be a Cause?

What causes chronic fatigue syndrome? The answer to this question continues to baffle researchers, so much so that some have even questioned whether the condition exists. Now, a new study by researchers from Cornell University in Ithaca, NY, may have shed light on a biological cause, after finding that patients with chronic fatigue have an altered gut microbiome.

Senior author Maureen Hanson, of the Departments of Molecular Biology and Genetics and Microbiology at Cornell, and colleagues publish their findings in the journal Microbiome.

Also referred to as myalgic encephalomyelitis (ME), chronic fatigue syndrome (CFS) is a condition characterized by extreme fatigue that does not improve with rest.

Diabetes and Stress: What's the Connection?

Diabetes is a complex disease, with varying risk factors and causes. Stress, especially long-term stress, interferes with the body's ability to manage blood sugar levels. As managing sugar levels becomes more difficult, the risk of long-term problems increases.

In this article, we will examine what stress is, how it is caused, and how it affects people living with diabetes. Since stress is a natural part of life, we will also discuss tips for managing and preventing stress.

Contents of this article:

1. What is stress?
2. How does stress affect people with diabetes?
3. Signs and symptoms of stress in people with diabetes
4. How can stress be managed and prevented?
5. Tips for reducing stress

Your Lifespan can be Reduced by Mood and Stress.

A study, published this week in Molecular Psychiatry, finds the genetic basis of a poorly understood phenomenon. Mood and stress are known to contribute to shortened lifespans, and researchers may now have identified the genes that are involved.

A team from Indiana University School of Medicine and the Scripps Research Institute, CA, conducted a multifaceted project investigating the genetic basis of premature aging in response to stress and psychiatric illness.

Using human participants and Caenorhabditis elegans, one of planet Earth's most-studied worms, the researchers delved into this intractable question.

They managed to identify a raft of genes that seem to control the impact of mood and stress responses on the longevity of an organism.

Bipolar, autism, and schizophrenia might share genetic origin

A new, in-depth genetic study, published in JAMA Psychiatry, finds a potential link between bipolar disorder, schizophrenia, and autism. Although the findings are tentative, they open the door to new avenues of investigation.

Bipolar disorder, previously called manic depression, causes dramatic shifts in mood, along with swings in activity and energy levels.

Thought to affect almost 1 to 3 percent of Americans, bipolar disorder can be an incredibly disruptive condition.

Bipolar disorder is thought to share a common genetic origin with a number of other psychiatric conditions. Although evidence of this connection is growing, the search is still in its infancy.

New research, led by Dr. James Potash, puts another gene-shaped piece in the jigsaw. The study was a joint venture, conducted at the University of Iowa Carver College of Medicine, Johns Hopkins School of Medicine in Baltimore, MD, and Cold Spring Harbor Laboratory, NY.

Why Do Celebrity Deaths Feel So Personal?

Prince's untimely death Thursday at the age of 57 left fans shocked and in mourning. While many express their grief, others are surprised to experience a strong personal reaction: I didn’t know him, some have thought, so why am I this upset?

The truth is, there’s no rulebook when it comes to grief, explains psychologist David Kaplan, chief professional officer of the American Counseling Association. The emotion is so swallowing and vast that it’s hard to pinpoint why it manifests in the ways that it does. But just because we can’t explain grief doesn’t mean it’s invalidated, Kaplan says — and that especially goes for grieving a celebrity.

“We grow up with these people,” Kaplan told The Huffington Post. “We see their movies, we hear their music on a regular basis and we really get to know them. In a sense, they become a member of our family — especially the ones we really like — so when they die, it’s like an extended member of our family dies. It’s somebody we feel like we know.”

These deaths also feel so personal because they resonate with us on a deeper, psychological level. We may grieve celebrities because our dream was to emulate their career path or because a celebrity death can also remind us of our mortality, Kaplan notes.
