    DON'T mind the gap. A woman has reached the age of 24 without anyone realising she was missing a large part of her brain. The case highlights just how adaptable the organ is. The discovery was made when the woman was admitted to the Chinese PLA General Hospital of Jinan Military Area Command in Shandong Province complaining of dizziness and nausea. She told doctors she'd had problems walking steadily for most of her life, and her mother reported that she hadn't walked until she was 7 and that her speech only became intelligible at the age of 6. Doctors did...

    The paper will be published Wednesday, August 27, 2014 in the Journal of Neuroscience. ... researchers used an MRI machine and the brains of 40 people between the ages of 18 and 25. They claim that the more marijuana a person smokes, the more those two neural regions get "damaged." Dr. Hans Breiter, a professor of psychiatry and behavioral sciences at Northwestern University Feinberg School of Medicine, co-authored the study. He says, "Anytime you find there's a relationship to the amount of marijuana consumed and you see differences of core brain regions involved in processing of rewards, the making of...

    Stimulating a particular region in the brain via non-invasive delivery of electrical current using magnetic pulses, called Transcranial Magnetic Stimulation, improves memory, reports a new Northwestern Medicine study. The discovery opens a new field of possibilities for treating memory impairments caused by conditions such as stroke, early-stage Alzheimer's disease, traumatic brain injury, cardiac arrest and the memory problems that occur in healthy aging. "We show for the first time that you can specifically change memory functions of the brain in adults without surgery or drugs, which have not proven effective," said senior author Joel Voss, assistant professor of medical social...

    Bad memories could be reversed after scientists discovered the part of the brain which links emotions to past events Bad memories of past trauma can leave people emotionally scarred for life. But now neuroscientists believe they can erase feelings of fear or anxiety attached to stressful events, in a breakthrough which could help treat depression or post-traumatic stress disorder. Researchers at MIT, US, have discovered which brain circuits attach emotions to memories, and crucially, how to reverse the link. They managed to ‘switch off’ feelings of fear in mice which had been conditioned to feel anxious. It is likely the...

    A new gene linked to suicide risk has been discovered, and researchers say the finding could lead to a blood test that predicts a person's risk of attempting suicide. The model correctly identified 80 percent to 96 percent of people who experienced suicidal thoughts or attempted suicide. It was more accurate among people at severe risk for suicide. If the findings are confirmed and lead to a blood test for suicide risk, such a test might be used to screen people in psychiatric emergency rooms or to determine how closely a person needs to be monitored for suicide risk, the...

    Fossilized Brain May Give Paleontologists Headache by Brian Thomas, M.S. * Who has ever heard of a fossilized brain? Few would expect such a discovery, yet it looks like that's what researchers found inside a Stone Age skull from Norway. If so, it would confirm a published creation prediction and challenge many evolutionary timescales. Ten archaeologists have been digging out fossilized human remains from a fjordside location called Brunstad, an area that encompasses two Stone Age human encampments.1 The scientists' findings include Norway's oldest unburned skeletal remains and a skull remnant with an unexpected attachment.

    Now, researchers from the Gladstone Institutes in San Francisco, CA, and the University of California-San Francisco reveal they have successfully reversed learning and memory deficits in mouse models of Alzheimer's through transplantation of healthy brain cells. The team transplanted inhibitory neuron progenitors - early-stage brain cells that can change into mature inhibitory regulator cells - into the hippocampus of two mouse models of Alzheimer's disease. One mouse model possessed the apoE4 gene, while the other had the apoE4 gene alongside a build-up of amyloid-beta - a protein also believed to play a role in Alzheimer's development. The researchers found that...

    Is There a Brain Region Associated with a Belief in Social Justice? Some people believe that we could live in a just world where everybody gets what they deserve. Others believe that's impossible. Now, neuroscientists say they have evidence that the "just world hypothesis" is a cognitive bias that's connected with a specific part of the brain. This does not mean there is a "social justice center" in your brain. What neurologist Michael Schaefer and colleagues discovered is that there is a slightly different pattern of electrical impulses shooting through the brains of people who believe in a just world....

The research, led by Jorge Ponseti at Germany’s University of Kiel, means that it may be possible to diagnose pedophiles in the future before they are able to offend. The findings, published in scientific journal Biology Letters, discovered that pedophiles have the same neurological reaction to images of those they find attractive as those of people with ordinary sexual predilections, but that all the relevant cerebral areas become engaged when they see children, as opposed to fellow adults. The occipital areas, prefrontal...

    Type 2 diabetes could cause the brain to age by up to two years every decade a person has the disease, researchers have claimed. It is the first time diabetes has been linked to a change in the size of the brain. The study also found that, contrary to common clinical belief, diabetes may not be directly associated with small vessel ischemic disease, where the brain does not receive enough oxygenated blood. 'We found that patients having more severe diabetes had less brain tissue, suggesting brain atrophy,' said lead author R. Nick Bryan, M.D., Ph.D., professor of radiology at the...

    The brains of older people only appear to slow down because they have so much information to compute, much like a full-up hard drive, scientists believe. Older people do not decline mentally with age, it just takes them longer to recall facts because they have more information in their brains, scientists believe. Much like a computer struggles as the hard drive gets full up, so to (sic) do humans take longer to access information, it has been suggested. Researchers say this slowing down it is not the same as cognitive decline. “The human brain works slower in old age,” said...

The top brain comprises the entire parietal lobe and the top (and larger) portion of the frontal lobe. The bottom comprises the smaller remainder of the frontal lobe and all of the occipital and temporal lobes.

Their study, in the journal Science, showed brain cells shrink during sleep to open up the gaps between neurons and allow fluid to wash the brain clean. They also suggest that failing to clear away some toxic proteins may play a role in brain disorders. Their findings build on last year's discovery of the brain's own network of plumbing pipes - known as the glymphatic system - which carry waste material out of the brain.

    Adolescence no longer ends when people hit 18, according to updated guidelines being given to child psychologists. The new directive is designed to extend the age range that child psychologists can work with from 18 years old up to 25. It is hoped the initiative will stop children being 'rushed' through their childhood and feeling pressured to achieve key milestones quickly, reports the BBC.

    It’s an inconvenient truth of aging: In our 30s and up, it gets increasingly harder for most of us to recall names, faces, and details from the past. Scientists have long debated whether this gradual decline is an early form of Alzheimer’s disease—a neurodegenerative condition that leads to severe dementia—or a distinct neurological process. Now, researchers have found a protein that distinguishes typical forgetfulness from Alzheimer’s and could lead to potential treatments for age-related memory loss. Previous studies have shown that Alzheimer’s disease and age-related memory loss involve different neural circuits in the hippocampus, a seahorse-shaped structure in the brain...

    Cross-section of miniature human brains termed cerebral organoids Miniature "human brains" have been grown in a lab in a feat scientists hope will transform the understanding of neurological disorders.The pea-sized structures reached the same level of development as in a nine-week-old foetus, but are incapable of thought.The study, published in the journal Nature, has already been used to gain insight into rare diseases.Neuroscientists have described the findings as astounding and fascinating. The human brain is one of the most complicated structures in the universe. Scientists at Institute of Molecular Biotechnology of the Austrian Academy of Sciences have now reproduced some...

    Roger Sperry won the Nobel Prize in 1981 for his work on what is now commonly known as right brain-left brain thinking. Sperry theorized that some very specific activities were controlled by one side of the human brain or the other — for example, the right side controlled creative tasks, while the left side was where logic, language and reasoning lived. People were fascinated by the idea, and in the three decades since, bookstores, television, the Internet and college psychology classes everywhere have been filled with endless discussions of the differences between right-brain, left-brain, and whole-brain thinkers. (Ironically, Sperry’s...

    In the new study, the team from Harvard randomly assigned 60 elderly people to drink two cups of flavanol-rich or flavanol-poor cocoa every day for a month. There weren't any overall differences between the high- and low-flavanol groups in terms of cognitive abilities, so the researchers looked a little deeper. They found that people who had compromised blood flow to the brain and white matter damage at the beginning of the study did show a difference after drinking the cocoa for a month: Blood flow in their brains improved by about 8%, and the time it took them to complete...
  • Scientists Make Mice “Remember” Things That Didn’t Happen

    Researchers manipulate mouse neurons to create a false memory; the work could lead to a better understanding of how memories form. Remember this: The red neurons are the brain cells in the hippocampus of a mouse carrying a new memory of a particular place. Scientists have created a false memory in mice by manipulating neurons that bear the memory of a place. The work further demonstrates just how unreliable memory can be. It also lays new ground for understanding the cell behavior and circuitry that controls memory, and could one day help researchers discover new ways to treat mental illnesses...

    8 Things We Simply Don't Understand About the Human Brain Despite all the recent advances in the cognitive and neurosciences, there’s still much about the human brain that we do not know. Here are 8 of the most baffling problems currently facing science. 1. What is consciousness? Without question, conscious awareness is the most astounding — and most perplexing — aspect of the human brain. It’s what makes us the unique, self-reflective creatures that we are. Consciousness allows us to experience and react to our environment in an apparently self-directed way. We’re not just zombies; we have our own private...
