'Memory molecule' stores memories in neocortex
08-16-2007 · EurekAlert!The "memory storage molecule" -- PKMzeta -- maintains long-term memories in the neocortex and its presence is continually required in order for the memory to endure, according to a finding by researchers at the Weizmann Institute in Rehovot, Israel and SUNY Downstate Medical Center in Brooklyn, N.Y.

- New Brandeis research sheds light on memory by erasing it
05-08-2007 · EurekAlert!
For years, scientists have studied the molecular basis of memory storage, trying to find the molecules that store memory, just as DNA stores genetic memory. In an important study published this week in the Journal of Neuroscience, Brandeis University researchers report for the first time that memory storage can be induced and then biochemically erased in slices of rat hippocampus by manipulating a so-called "memory molecule," a protein kinase known as CaMKII.

- 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.

- UCLA/Toronto researchers unlock key to memory storage in brain
04-19-2007 · EurekAlert!
Scientists know little about how the brain chooses cells to encode and store memories. Now a UCLA-University of Toronto team has discovered that a protein called CREB controls the odds of a neuron participating in memory formation. The April 20 edition of Science reports the findings, which suggest a new approach for preserving memory in people suffering from Alzheimer's or other brain injury. Memories could be guided into healthy cells and away from sick cells in dying regions of the brain.

- Study shows children less prone to false memories, implications for eyewitness testimony
04-30-2007 · EurekAlert!
Sizeable literature has shown that as we grow into adulthood, our memory accuracy improves. However, psychologists Charles Brainerd and Valerie Reyna of Cornell University believe that adults may have less acurate memories than children under certain circumstances.

- New alzheimer's drug shows promise in clinical trial
11-02-2006 · EurekAlert!
The only drugs currently available for Alzheimer's patients are those that alleviate symptoms, but a team of scientists led by Paul Aisen, MD, director of the Memory Disorders program at Georgetown University Medical Center, is testing a new class of drugs that actually target the molecule believed to cause the disease.

- Structure essential for brain remodeling identified
12-06-2006 · EurekAlert!
During learning and memory formation, the brain builds or remodels tiny structures on the surface of its nerve cells to store the new information. Now, a team led by Duke University Medical Center researchers has discovered where the brain gets the raw materials for such construction -- and has even taken "home movies" of the process.

- Blind people are 'serial memory' whizzes
06-21-2007 · EurekAlert!
Compared to people with normal vision, those who were blind at birth tend to have excellent memories. Now, a new study reported online on June 21st in the journal Current Biology, a publication of Cell Press, shows that blind individuals are particular whizzes when it comes to remembering things in the right order.
