Disrupting Cocaine-memories To Battle Addiction

Novel use of genetic testing methods helped public health officials control and limit the further spread of four outbreaks of foodborne hepatitis A virus in 2003 related to the consumption of green onions, according to a detailed analysis published in the October 15 issue of The Journal of Infectious Diseases, now available online. The authors of the study, Joseph J. Amon, PhD, MSPH, and c...

Neuroscientists discover new cell type that may help brain maintain memories of smells

Neuroscientists at Case Western Reserve University School of Medicine have discovered a new cell type in the part of the brain that processes our sense of smell. This new cell type, the Blanes cell, is a member of a group of previously unstudied brain cells described by the Spanish neuroanatomist Blanes (pronounced blon ?es) in the late 1800s. Blanes cells have unusual properties which may help...

Proteins anchor memories in our brain

Scientists have discovered that autoimmunity can be triggered in the thymus, where the immune system's T cells develop, if T cells fail to recognize just one of the body's thousands of proteins as "self." The research confirms an emerging view that autoimmunity can start in this cradle of the immune system, and not only at the sites where autoimmune diseases emerge, such as the pancreas in the c...

Researchers discover mechanism that determines when detailed memories are retained

The levels of a chemical released by the brain determine how detailed a memory will later be, according to researchers at UC Irvine. The neurotransmitter acetylcholine, a brain chemical already established as being crucial for learning and memory, appears to be the key to adding details to a memory. In a study with rats, Norman Weinberger, research professor of neurobiology and behavior, a...

Memories: It's all in the packaging, scientists say

Researchers at UC Irvine have found that how much detail one remembers of an event depends on whether a certain portion of the brain is activated to "package" the memory. In experiments using functional...

Memories change with age

On an average younger people remember important events in detail, older people recall more about thoughts, feelings and context. It's known that memory changes with age - some researchers believe that it deteriorates,// others that we start to remember in a different way. Psychologists in Toronto have been comparing how people of different ages remember significant events, like their first kiss....

Research Finds How Post-traumatic Stress Leads to Long-Lasting Memories

The amygdala of the brain may be responsible for post-traumatic nightmares according// to a new research. . Post-traumatic stress is a well recognized condition that results in unpleasant memories that can keep haunting a person for all their life. Now researchers have discovered what causes this following experiments on rats. This will also explain why an emotionally arousing event...

Peaceful Slumber said to Restore Memories

It's not just a matter of physical recharge. Researchers say sleep can rescue memories in a biological process of storing and consolidating them deep in the brain's complex circuitry.Researchers who conducted the experiments said the results may influence how students learn, and someday could be incorporated into treatments for mental illnesses involving memories, such as post-traumatic stress...

Humans Found To Have The Ability To Block Unwanted Memories

A new study shows there may be reason to believe we have a selective memory . It seems a mechanism in the brain may block unwanted memories. Researchers from Stanford University studied 24 volunteers // between ages 19 and 31. Participants were given 36 pairs of unrelated words and asked to remember them at five-second intervals. Researchers then divided the 36 word pairs into three sets of...

Sensitive teeth could become bad memories

From children to adults everyone has had a sensitive tooth at some point of their life. A visit to the dentist will tell you that 'your tooth is worn out' or 'you brush in a hard way, so your teeth are damaged.' // Now scientists from the Leeds University have come out with a solution that could make sensitive teeth a bad memory. The researchers have developed a solution which they cla...
