Researchers at Michigan State, Chicago, and WUSTL says sleep may reduce mistakes in memory for both the young and the old.
They studied the presence of false memory in groups of college students. Previous research has shown that sleep improves memory, but this study address errors in memory.
The study was published in the journal Learning & Memory.

Jon Hamilton reports on a recent German study in Science that says that for more than 50 years, scientists who study the brain have been misled by squid. They did experiments on squid nerve cells thinking that those cells were good models for the human nervous system.
WUSTL radiology professor Marcus Raichle, who does brain imaging studies, says, "There is always this tendency that if you're working in an area and your experiments are working well and you're getting good data, to not think of the larger context in which this is occurring."

Cindy McCain explains the need for more funding for research to cure migraine headaches. As a nation, we spend very little on research into the causes and treatments of migraines. It is estimated that the NIH spends less than $13 million a year for migraine research. Neurology professor Todd Schwedt of WUSTL's Headache Center says that based on the burden migraine exacts from society, funding should be closer to $260 million.

New Swiss research published in Science suggests that young animals may have a mechanism that allows them to jettison traumatic memories, but experts say it's unclear whether humans of any age can do the same. Includes comments by WUSTL psychology professor and memory specialist Mark McDaniel.

WUSTL psychology doctoral student Andrew Butler said students who learn history through watching blockbuster movies may be doomed to repeat history.
". . . when information in the film directly contradicted the text, people often falsely recalled the misinformation portrayed in the film."
The findings are published in the journal Psychological Science.

Scientists know surprisingly little about the common sensation of itching. But in a recent study of mice, researchers identified specific nerve cells that pass along an itch signal to the brain. And these cells appear to be independent of the pathway for pain. WUSTL anesthesiology professor and co-author Zhou-Feng Chen comments on the study that was published in Science Express.

While a number of studies in recent years have found toddlers -- and even babies -- can suffer from major depressive disorder, doctors have debated whether preschool depression was an isolated blip in a child's development or a sign of future problems. According to a new WUSTL study published in the Archives of General Psychiatry, preschoolers can suffer from major depression, and those children are likely to face depression again in elementary school.

Technological and computational advances have enabled researchers to image the brain's wrinkled exterior in stunning detail, mapping the size and shape of each fold. Scientists pursuing this new discipline of "cortical cartography'' expect it to yield insights into how the brain develops and what happens when things go awry. WUSTL neurobiologist David Van Essen comments.

Are some people hardwired to get the blues? Scientists have long believed that a tendency toward melancholy runs in families. A new study published on June 16 in JAMA now threatens to send researchers back to the drawing board. The meta-analysis of 14 prior studies concludes that the so-called depression gene may not be associated with an elevated risk for depression, as many researchers had believed. WUSTL psychiatric geneticist Alexandre Todorov, whose 2007 peer-reviewed study was included in the JAMA piece, comments.

A single episode of low blood sugar severe enough to require prompt medical attention increases a person's risk of developing dementia in old age, a study in people with diabetes suggests. "This is a worrisome association," says WUSTL endocrinologist Philip Cryer. But he cautions that an association doesn't prove that one factor causes the other.
