redOrbit Staff & Wire Reports - Your Universe Online Emotional memories can be erased shortly after they are formed through behavioral intervention alone, without the aid of medications, according to a new study published Thursday in the journal Science. The breakthrough offers a major step forward in understanding where fearful memories are processed in the brain, and how to permanently erase them. The research could be particularly helpful for people suffering from conditions such...

Is sleep learning possible? A new Weizmann Institute study appearing today in Nature Neuroscience has found that if certain odors are presented after tones during sleep, people will start sniffing when they hear the tones alone — even when no odor is present — both during sleep and, later, when awake. In other words, people can learn new information while they sleep, and this can unconsciously modify their waking behavior. Sleep-learning experiments are notoriously difficult to...

A new study by researchers at Stanford University, using a technique that manipulates light to control brain cells, has shown that broken sleep causes memory impairment in mice. Until recently scientists have been unable to separate the effects on the brain of different sleep patterns. But in the newest study, they were able to overcome that problem using the new method, known as optogenetics. Published in the Proceedings of the National Academy of Sciences (PNAS), the study could help...

The process we use to store memories is more complex than previously thought, New York University neuroscientists have found. Their research, which appears in the journal the Proceedings of the National Academy of Sciences, underscores the challenges in addressing memory-related ailments, such as post-traumatic stress disorder. The researchers looked at memory consolidation and reconsolidation. Memory consolidation is the neurological process we undergo to store memories after an experience....

Works only if given during windows of memory malleability A naturally occurring growth factor significantly boosted retention and prevented forgetting of a fear memory when injected into rats' memory circuitry during time-limited windows when memories become fragile and changeable. In the study funded by the National Institutes of Health, animals treated with insulin-like growth factor (IGF-II) excelled at remembering to avoid a location where they had previously experienced a mild shock. "To...

Scientists, surprised by their own findings, report that the best way to not forget a newly learned poem, card trick or algebra equation may be to take a quick nap. Researchers in Germany showed in experiments that the brain is better during sleep than during wakefulness at resisting attempts to scramble or corrupt a recent memory. Their study provides new insights into the hugely complex process by which people store and retrieve deliberately acquired information. Earlier research showed...

The brain is capable of holding and retrieving memories for specific fears, revealing a more sophisticated storage and recall capacity than previously thought, neuroscientists have found. The study, which appears in the journal Nature Neuroscience, may have implications for treating post-traumatic stress syndrome"”as scientists begin to understand how different fears are stored in the brain, they can move toward addressing specific fear memories. The research was conducted by...

Our memories are strengthened during periods of rest while we are awake, researchers at New York University have found. The findings, which appear in the latest issue of the journal Neuron, expand our understanding of how memories are boosted -- previous studies had shown this process occurs during sleep, but not during times of awake rest. "Taking a coffee break after class can actually help you retain that information you just learned," explained Lila Davachi, an assistant professor in...

Recalling emotional memory opens window of opportunity to rewrite it Scientists have for the first time selectively blocked a conditioned fear memory in humans with a behavioral manipulation. Participants remained free of the fear memory for at least a year. The research builds on emerging evidence from animal studies that reactivating an emotional memory opens a 6-hour window of opportunity in which a training procedure can alter it. "Our results suggest a non-pharmacological, naturalistic...

 According to a research abstract that will be presented on Thursday, June11, at SLEEP 2009, the 23rd Annual Meeting of the Associated Professional Sleep Societies, sleep selectively preservers memories that are emotionally salient and relevant to future goals when sleep follows soon after learning. Effects persist for as long as four months after the memory is created.Results indicate that the sleeping brain seems to calculate what is most important about an experience and selects only...


Word of the Day
tesla
  • The unit of magnetic flux density in the International System of Units, equal to the magnitude of the magnetic field vector necessary to produce a force of one newton on a charge of one coulomb moving perpendicular to the direction of the magnetic field vector with a velocity of one meter per second. It is equivalent to one weber per square meter.
This word is named for Nikola Tesla, the inventor, engineer, and futurist.
