- Neuroscientist records surprising brain 'dialogue' during sleep
03-05-2007 · EurekAlert!
A Brown University-led research team has, for the first time, recorded activity inside the cells of the hippocampus while simultaneously measuring activity in the neocortex. Recordings from these two brain regions -- seats of memory creation and storage -- revealed a surprisingly complex pattern of activity. These findings, in the Proceedings of the National Academy of Sciences, are part of a growing body of evidence that challenges traditional theories of the role of sleep in learning and memory.

- Children's memory of long-ago events may be more accurate than previously thought
07-20-2007 · EurekAlert!
Research with 5- and 6-year olds indicates that children’s memories can be accurate even when interviewed well after an event. A long delay (three versus twenty one days), had no effect on the accuracy of children's memory of certain activities. The researchers observed differences in memory depending on how much the details varied each time the activity took place. These findings have implications for interviewing child witnesses who are interviewed a while after an incident.

- To understand the big picture, give it time -- and sleep
04-20-2007 · EurekAlert!
Memorizing a series of facts is one thing, understanding the big picture is quite another. Now a new study demonstrates that relational memory -- the ability to make logical "big picture" inferences from disparate pieces of information -- is dependent on taking a break from studies and learning, and even more important, getting a good night's sleep.

- Special chiropractic adjustment lowers blood pressure
03-14-2007 · EurekAlert!
A Chicago-area study of 50 individuals with a misaligned Atlas vertebra (located high in the neck) and high blood pressure showed that after a one-time specialized chiropractic adjustment, blood pressure decreased significantly. The decrease was equal to taking two blood-pressure drugs at once. The results are published in the online March 2 issue of the Journal of Human Hypertension.

08-07-2007 · EurekAlert!
Neal Koblitz is a mathematician who, starting in the 1980s, becamefascinated by mathematical questions in cryptography. In his article"The Uneasy Relationship Between Mathematics and Cryptography," toappear in the September 2007 issue of the Notices of the AMS, Koblitzrecalls some of the drama and conflict that he witnessed while doingresearch in mathematical cryptography in the past two decades.

- Speak, memory: Research challenges theory of memory storage
11-14-2006 · EurekAlert!
During sleep, freshly minted memories move from the hippocampus, part of the "old" brain, to the neocortex, or "new" brain, for long-term storage. This has been the reigning theory for decades. Brown University research provides the strongest proof yet of this interaction between the old and new brains -- and offers surprising evidence that challenges critical details of this theory of learning and memory. Results appear in Nature Neuroscience.

- New research shows why too much memory may be a bad thing
03-28-2007 · EurekAlert!
New research from Columbia University Medical Center may explain why people who are able to easily and accurately recall historical dates or long-ago events, may have a harder time with word recall or remembering the day’s current events -- they may have too much memory.

- Brain cell growth diminishes long before old age strikes, animal study shows
10-15-2007 · EurekAlert!
Soon after marmosets reach adulthood, the rate at which new neural cells form in the hippocampus region of the animals' brains begins to decline. The hippocampus is associated with both learning and memory. While similar observations have been made previously in the brains of rodents, this is the first time the decrease in new cell growth has been noted in a primate.
