Phase locking of hippocampal interneuron membrane potential
If I can't remember this morning where I put my car keys last night, it's due to my memory failing me again. Scientists at the Max Planck Institute for Medical Research in Heidelberg have been investigating how memories might be consolidated. Their new study offers the hitherto strongest proof that new information is transferred between the hippocampus, the short term memory area, and the cerebral cortex during sleep. According to their findings and contrary to previous assumptions, the cerebral cortex actively controls this transfer. The researchers developed a new technique for their investigations which promises previously impossible insight into the largely under-researched field of information processing in the brain (Nature Neuroscience, November 2006).

Human Memory Gene Identified
Researchers at the Translational Genomics Research Institute (TGen) today announced the discovery of a gene that plays a significant role in memory performance in humans. The findings, reported by TGen and research colleagues at the University of Zurich in Switzerland, Banner Alzheimer's Institute, and Mayo Clinic Scottsdale, appear in the October 20 issue of Science. The study details how researchers associated memory performance with a gene called Kibra in over 1,000 individuals --both young and old-- from Switzerland and Arizona. This study is the first to describe scanning the human genetic blueprint at over 500,000 positions to identify cognitive differences between humans.

How the Brain Loses Plasticity of Youth
A protein once thought to play a role only in the immune system could hold a clue to one of the great puzzles of neuroscience: how do the highly malleable and plastic brains of youth settle down into a relatively stable adult set of neuronal connections? Harvard Medical School researchers report in the August 17 Science Express that adult mice lacking the immune system protein paired-immunoglobulin like receptor-B (PirB) had brains that retained the plasticity of much younger brains, suggesting that PirB inhibits such plasticity.

Apple Juice Inproves Memory By Boosting Acetylcholine Production
For those who think that apple juice is a kid's drink, think again. Apples and apple juice may be among the best foods that baby boomers and senior citizens could add to their diet, according to new research that demonstrates how apple products can help boost brain function similar to medication. Animal research from the University of Massachusetts Lowell (UML) indicates that apple juice consumption may actually increase the production in the brain of the essential neurotransmitter acetylcholine, resulting in improved memory. Neurotransmitters such as acetylcholine are chemicals released from nerve cells that transmit messages to other nerve cells. Such communication between nerve cells is vital for good health, not just in the brain, but throughout the body.

A recent volume of the Annals of the New York Academy of Sciences takes a closer look at how music evolved and how we respond to it. Contributors to the volume believe that animals such as birds, dolphins and whales make sounds analogous to music out of a desire to imitate each other. This ability to learn and imitate sounds is a trait necessary to acquire language and scientists feel that many of the sounds animals make may be precursors to human music.

Short term synaptic plasticity play a widespread role in information processing
Animals' neurons, and the synapses that connect them, are constantly changing. This plasticity is thought to underlie learning and memory. Take the rat in the maze. As he learns to navigate a new environment, familiarity with the space is reflected in the neuronal activity of a small almond-shaped brain structure called the hippocampus. Neurons in the hippocampus are generally quiescent. But when the rat meanders into a spot that a specific neuron prefers, called its “place field,” the neuron responds with high-frequency bursts of spikes. As the rat's familiarity with the maze increases over only a few minutes, so does the reliability by which hippocampal neurons respond to their preferred place. This short-term experience modifies the neurons' responses, and very likely the synapses, although the synaptic mechanisms of short-term plasticity in this context have not been fully described.

Sleepy fruit flies provide clues to learning and memory
Researchers at the University of Pennsylvania School of Medicine have discovered that a brain region previously known for its role in learning and memory also serves as the location of sleep regulation in fruit flies. Through further examination of this brain structure, researchers hope to shed light on sleep regulation and its role in memory. Despite its importance in everyday human function, very little is known about the regulation of sleep. In search of the underlying brain region responsible for sleep regulation, senior author Amita Sehgal, PhD, Professor of Neuroscience and a Howard Hughes Medical Institute (HHMI) Investigator, and colleagues turned their attention to the fruit fly.

Memory - Retention Begins While You're Still Awake
There's some unwritten law of stadium parking that says after any event some fraction of hapless souls must perform an embarrassing reenactment of Dude, Where's My Car? It might seem like a simple thing to remember until you consider that the brain must often process and retain new memories while simultaneously tending to several unrelated cognitive tasks. Though it's not exactly clear how the brain processes a recent memory, evidence suggests that a good nap during an event might prevent parking mishaps. Many studies have shown that brain regions activated while learning a task are reactivated during sleep, suggesting that this “offline” processing facilitates memory retention. But when does the memory consolidation process begin?

How memory is stored at the level of neurons
Researchers from The University of Texas at Austin studying electric fish have gained new insight into how memory is stored at the level of neurons. Their finding, published in the Feb. 16 issue of Neuron, could help researchers better understand memory formation and neural disorders like epilepsy in humans. Dr. Harold Zakon, Dr. Jörg Oestreich and colleagues show that when electric fish zap each other in dark waters, their neurons store a memory of the sizzling communiqué by turning on special cell membrane channels. The channels give the fish neurons the ability to retain a memory long after its original stimulus is gone.

The ability to retain memory about the details of a natural scene is unaffected by the distraction of another activity and this information is retained in "working memory" according to a study recently published in Journal of Vision, an online, free access publication of the Association for Research in Vision and Ophthalmology (ARVO). These results reinforce the notion that humans maintain useful information about previous fixations in long-term working memory rather than the limited capacity of visual short-term memory (VSTM).

Brain size matters for intellectual ability
Brain size matters for intellectual ability and bigger is better, McMaster University researchers have found. The study, led by neuroscientist Sandra Witelson, a professor in the Michael G. DeGroote School of Medicine, and published in the December issue of the journal Brain, has provided some of the clearest evidence on the underlying basis of differences in intelligence. The study involved testing of intelligence in 100 neurologically normal, terminally ill volunteers, who agreed that their brains be measured after death. It found bigger is better, but there are differences between women and men. In women, verbal intelligence was clearly correlated with brain size, accounting for 36 percent of the verbal IQ score. In men, this was true for right-handers only, indicating that brain asymmetry is a factor in men.

New Research on Mental Time Travel
Neuroscientists at Princeton University have developed a new way of tracking people's mental state as they think back to previous events -- a process that has been described as "mental time travel." The findings, detailed in the Dec. 23 issue of Science, will aid efforts to learn more about how people mine the recesses of memory and could have a wide-ranging impact in the field of neuroscience, including studies of brain disorders such as Alzheimer's disease. The researchers showed nine participants a series of pictures and then asked them to recall what they had seen. By applying a computerized pattern-recognition program to brain scanning data, the researchers were able to show that the participants' brain state gradually aligned with their brain state from when they first studied the pictures. This supports the theory that memory retrieval is a form of mental time travel.

How brain replenishes memory-making molecules
New research on living neurons has clarified how the brain refreshes the supply of molecules it needs to make new memories. The discovery by scientists at UCSF is reported today in the December 22 issue of the journal Neuron and is featured on the journal's cover. Memory formation is thought to involve a strengthening of the communication between neurons in the part of the brain known as the hippocampus. Researchers know that this increased communication results from a surge in the number of receptors on one neuron that is available to bind to the neurotransmitter glutamate released from another neuron. The two neurons meet at a synapse.

Synchronized Brain Interactions Associated with Memory and Decision-Making
Next time you lose your keys, you might consider the Clark's nutcracker. During the fall, this woodland resident collects over 30,000 seeds, buries them in discrete locations, then returns over the winter to retrieve its cache. This improbable behavior requires the coordinated activity of different brain structures to integrate spatial coordinates encoded in the hippocampus with memories of how to find the seed stash. As it turns out, food-storing birds have a significantly larger hippocampus—a brain region involved in spatial organization and memory—than nonhording species.

"Sharp" older brains store memories differently than younger brains
Researchers working with rats have found the first solid evidence that still "sharp" older brains store and encode memories differently than younger brains. This discovery is reported by a Johns Hopkins team in the issue of Nature Neuroscience released online Nov. 13. Should it prove to apply as well to human brains, it could lead eventually to the development of new preventive treatments and therapies based on what healthy older brains are doing, rather than on the less relevant, younger brain model, according to study co-author Michela Gallagher, chair of the Department of Psychological and Brain Sciences at Johns Hopkins' Zanvyl Krieger School of Arts and Sciences.

Impaired Olfactory Memory by Spatially Controlled Switch of AMPA Receptors
The smell of baking bread, the perfume of flowers, the tang of sea air—your nose can sense and distinguish between these smells and thousands more. The sense of smell—managed by the olfactory system—is a crucial tool for sensing the environment. Thousands of low molecular weight molecules bind to a vast repertoire of odor receptors on olfactory sensory neurons in the nose. These neurons extend long projections into an area of the forebrain known as the olfactory bulb, where chemical messengers (neurotransmitters) pass on information to other neurons elsewhere in the brain. In ways that are only just beginning to be understood, all this information is integrated by neural circuits in the brain so that different odors can be learned and discriminated; in addition, changes in neuron activity are responsible for remembering odors.

Misty Watercolor Memories, Biochemically Speaking
Eyewitness testimony has a unique ability to convince juries. The attorney asks the witness to identify the guilty party. The witness points to the defendant, the crowd gasps, and the judge pounds her gavel, demanding order in the court. The jurors casually scribble something in their notes, and everybody knows that the fate of the accused has been sealed. But how reliable is a witness’s memory, especially after rehearsing the testimony ad nauseam with a team of lawyers? When a witness presents testimony, is she really remembering the event, or is she remembering something she remembered? Does the initial memory remain intact, or does it degrade like a copy of a copy?
