  • Brains of People with Chronic Fatigue Syndrome Offer Clues About Disorder

    Patients with chronic fatigue syndrome are accustomed to disappointment. The cause of the disorder remains unknown; it can be difficult to diagnose, and treatment options are few. Many patients are still told to seek psychiatric help. But two recent studies — one from investigators at Stanford a few weeks ago and another from a Japanese research team published earlier this year — have found that the brains of people with chronic fatigue syndrome differ from those of healthy people, strengthening the argument that serious physiological dysfunctions are at the root of the condition. Both studies were small, however, and their...

    AUSTIN, Texas (AP) — The University of Texas at Austin is missing about 100 brains — about half of the specimens the university had in a collection of brains preserved in jars of formaldehyde. One of the missing brains is believed to have belonged to clock tower sniper Charles Whitman. "We think somebody may have taken the brains, but we don't know at all for sure," psychology Professor Tim Schallert, co-curator of the collection, told the Austin American-Statesman (http://bit.ly/11R7vym ). His co-curator, psychology Professor Lawrence Cormack, said, "It's entirely possible word got around among undergraduates and people started swiping them...

    **SNIP** The amendment's author, Republican Senator Charles Grassley, argued that if Obamacare plans were good enough for the American public, they were good enough for Congress. Democrats, eager to pass the reforms, went along with it. But it soon became apparent the provision contained no language that allowed federal contributions toward their health plans that cover about 75 percent of the premium costs. This caused fears that staff would suddenly face sharply higher healthcare costs and leave federal service, causing a "brain drain" on Capitol Hill. But Wednesday's proposed rule from the OPM, the federal government's human resources agency, means...

    Experimental mice have been telling us this for years, but pot-smoking humans didn't want to believe it could happen to them: Compared with a person who never smoked marijuana, someone who uses marijuana regularly has, on average, less gray matter in his orbital frontal cortex, a region that is a key node in the brain's reward, motivation, decision-making and addictive behaviors network. More ambiguously, in regular pot smokers, that region is better connected than it is in non-users:The flow of signal traffic is speedier to other parts of that motivation and decision-making network, including across the superhighway of "white matter"...

    Washington Post ^ | Oct 26, 2014 | Fredrick Kunkle
    In case anyone needed another reason to love chocolate, a new study suggests that a natural compound found in cocoa, tea and some vegetables can reverse age-related memory loss. The findings suggest that the compound increases connectivity and, subsequently, blood flow in a region of the brain critical to memory, the researchers said. Researchers said that if a person had the memory of a typical 60-year-old at the beginning of the study, after three months, on average, that person’s memory would function more like a 30- or 40-year-old’s. The researchers also cautioned that more work is needed because of the...

    The new research could help doctors to quickly identify patients who are aware despite appearing unresponsive and unable to communicate. Researchers from University of Cambridge in the UK have identified hidden networks in vegetative patients that could support consciousness, even when a patient appear to be unresponsive. There’s been a lot of interest lately into how much patients in vegetative states, such as comas, are aware of their surroundings. Recently, research involving functional magnetic resonance imaging (fMRI) scanning has shown that even patients who are unable to respond or move are able to carry out mental tasks, such as imagining...

    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...

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.

    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.

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...

    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...

    This was proven by a study by Grethe Jensen and co. (1993), who meticulously counted neurons in matched samples of non-alcoholics and alcoholics. What they found was that there was no real difference in the density or overall number of neurons between the two groups. In every group, those who drank moderately on a regular basis throughout their lives always had a diminished chance of becoming mentally impaired in their old age compared to those who didn't drink at all or almost never drank. Now for the negative (there's a lot when it comes to intemperate alcohol consumption, so I'll...

    At least one in five patients declared brain dead and approved as organ donors by one organ donation organization, are in fact still alive and are being killed by the removal of vital organs, a lawsuit filed last week in Manhattan alleges. The suit outlines the ghoulish worst-case scenario, one that was widely dismissed as scaremongering in the early days of the development of organ transplant technology, but which is getting a second hearing amidst growing concerns that coercion and abuse are becoming increasingly common in the highly lucrative transplant business. Patrick McMahon, a nurse practitioner and Air Force combat...

    In modern times there has been a tendency to downplay the differences between men and women, preferring to see whatever differences have historically existed as simply social constructs. This thinking was insisted upon by many as a kind of political correctness that must be held otherwise punishment and excoriation was sure to follow.Nevertheless, most people with common sense have always known that men and women are very different, and that these differences are not simply the result of social constructs or the way people were raised.Now scientists have made discoveries not only affirming that men and women are different, but...

    PHILADELPHIA — A new brain connectivity study from Penn Medicine published today in the Proceedings of National Academy of Sciences found striking differences in the neural wiring of men and women that’s lending credence to some commonly-held beliefs about their behavior. n one of the largest studies looking at the “connectomes” of the sexes, Ragini Verma, PhD, an associate professor in the department of Radiology at the Perelman School of Medicine at the University of Pennsylvania, and colleagues found greater neural connectivity from front to back and within one hemisphere in males, suggesting their brains are structured to facilitate connectivity...
  • Your Brain Has 2 Clocks

    Did you make it to work on time this morning? Go ahead and thank the traffic gods, but also take a moment to thank your brain. The brain’s impressively accurate internal clock allows us to detect the passage of time, a skill essential for many critical daily functions. Without the ability to track elapsed time, our morning shower could continue indefinitely. Without that nagging feeling to remind us we’ve been driving too long, we might easily miss our exit.

    One of the smallest parts of the brain is getting a second look after new research suggests it plays a crucial role in decision making. A University of British Columbia study published today in Nature Neuroscience says the lateral habenula, a region of the brain linked to depression and avoidance behaviors, has been largely misunderstood and may be integral in cost-benefit decisions. "These findings clarify the brain processes involved in the important decisions that we make on a daily basis, from choosing between job offers to deciding which house or car to buy," says Prof. Stan Floresco of UBC's Dept....

    So here I am sitting watching the History channel, instead of NFL and they are talking about the mystery of 3, the ancient Egyptians, monoliths, and different dimensions. Out of nowhere they make a leap to a discussion of the White House and President 0bama authorizing the Brain Initiative. So I am a little more than caught off guard. Being the curious sort I immediately jump on my computer to look up this 'initiative,' and why our government would be so interested in our brains. Much to my surprise the website comes up on the first try and initially looks...

    If you move the view to the side, however, you can see the top and bottom parts of the brain, demarcated largely by the Sylvian fissure, the crease-like structure named for the 17th-century Dutch physician who first described it. 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. Our theory's roots lie in a landmark report published in 1982 by Mortimer Mishkin and Leslie G. Ungerleider of the National Institute of Mental Health....
