Scientists identify that memories can be lost and found
(Press-News.org) A team of scientists believe they have shown that memories are more robust than we thought and have identified the process in the brain, which could help rescue lost memories or bury bad memories, and pave the way for new drugs and treatment for people with memory problems.
Published in the journal Nature Communications a team of scientists from Cardiff University found that reminders could reverse the amnesia caused by methods previously thought to produce total memory loss in rats. .
"Previous research in this area found that when you recall a memory it is sensitive to interference to other information and in some cases is completely wiped out.
"Our research challenges this view and we believe proves this not the case," according to Dr Kerrie Thomas, who led the research.
"Our research found that despite using a technique in the brain thought to produce total amnesia we've been able to show that with strong reminders, these memories can be recovered,"
Whilst the results were found in rats, the team hope it can be translated into humans and new drugs and treatments could be developed for people suffering with memory disorders.
Dr Thomas added: "We are still a very long way off from helping people with memory problems.
"However, these animal models do accurately reflect what's happening in humans and suggest that our autobiographical memories, our self-histories, are clouded by new memories rather than actually lost. This is an exciting prospect in terms of treating psychiatric illness associated with memory disorders such as post-traumatic stress disorder, schizophrenia and psychosis.
"We can now devise new drugs or behavioural strategies that can treat these memory problems in the knowledge that we won't overwrite our experiences," she added.

Dogs have a specialized region in their brains for processing faces, a new study finds. PeerJ is publishing the research, which provides the first evidence for a face-selective region in the temporal cortex of dogs.
"Our findings show that dogs have an innate way to process faces in their brains, a quality that has previously only been well-documented in humans and other primates," says Gregory Berns, a neuroscientist at Emory University and the senior author of the study.
Having neural machinery dedicated to face processing suggests that this ability is hard-wired ...
Trauma may cause distinct and long-lasting effects even in people who do not develop PTSD (post-traumatic stress disorder), according to research by scientists working at the University of Oxford's Department of Psychiatry. It is already known that stress affects brain function and may lead to PTSD, but until now the underlying brain networks have proven elusive.
Led by Prof Morten Kringelbach, the Oxford team's systematic meta-analysis of all brain research on PTSD is published in the journal Neuroscience and Biobehavioural Reviews. The research is part of a larger ...
CHARLOTTESVILLE, VA (AUGUST 4, 2015). Researchers at the University of Virginia (UVa) examined the number and severity of subconcussive head impacts sustained by college football players over an entire season during practices and games. The researchers found that the number of head impacts varied depending on the intensity of the activity. Findings in this case are reported and discussed in "Practice type effects on head impact in collegiate football," by Bryson B. Reynolds and colleagues, published today online, ahead of print, in the Journal of Neurosurgery.

August 4, 2015 -- Treating maternal psychiatric disorder with commonly used antidepressants is associated with a lower risk of certain pregnancy complications including preterm birth and delivery by Caesarean section, according to researchers at Columbia University's Mailman School of Public Health, Columbia University Medical Center, and the New York State Psychiatric Institute. However, the medications -- selective serotonin reuptake inhibitors, or SSRIs -- resulted in an increased risk of neonatal problems. Findings are published online in the American Journal of Psychiatry.
Chestnut Hill, MA (August 4, 2015): It's been said that "Those who don't know history are doomed to repeat it," but even if you know your own history, that doesn't necessarily help you with self-control. New research published in the Journal of Consumer Psychology shows the effectiveness of memory in improving our everyday self-control decisions depends on what we recall and how easily it comes to mind.
"Despite the common belief that remembering our mistakes will help us make better decisions in the present," says the study's lead author, Hristina Nikolova, Ph.D., an ...
PHILADELPHIA - The roughly nine million Americans who rely on prescription sleeping pills to treat chronic insomnia may be able to get relief from as little as half of the drugs, and may even be helped by taking placebos in the treatment plan, according to new research published today in the journal Sleep Medicine by researchers from the Perelman School of Medicine at the University of Pennsylvania. Their findings starkly contrast with the standard prescribing practices for chronic insomnia treatment.
The findings, which advocate for a dosing strategy of smaller and fewer ...
Research on alcohol-use disorders consistently shows problem drinking decreases as we age. Also called, "maturing out," these changes generally begin during young adulthood and are partially caused by the roles we take on as we become adults. Now, researchers collaborating between the University of Missouri and Arizona State University have found evidence that marriage can cause dramatic drinking reductions even among people with severe drinking problems. Scientists believe findings could help improve clinical efforts to help these people, inform public health policy changes ...
Here's a quick task: Take a look at the sentences below and decide which is the most effective.
(1) "John threw out the old trash sitting in the kitchen."
(2) "John threw the old trash sitting in the kitchen out."
Either sentence is grammatically acceptable, but you probably found the first one to be more natural. Why? Perhaps because of the placement of the word "out," which seems to fit better in the middle of this word sequence than the end.
In technical terms, the first sentence has a shorter "dependency length" -- a shorter total distance, in words, between ...

Many people who are skeptical about vaccinating their children can be convinced to do so, but only if the argument is presented in a certain way, a team of psychologists from UCLA and the University of Illinois at Urbana-Champaign reported today. The research appears in the online early edition of the journal Proceedings of the National Academy of Sciences.
The finding is especially important because the number of measles cases in the U.S. tripled from 2013 to 2014. The disease's re-emergence has been linked to a trend of parents refusing to vaccinate their children.
