Exercise increases brain growth factor and receptors, prevents stem cell drop in middle age
A new study confirms that exercise can reverse the age-related decline in the production of neural stem cells in the hippocampus of the mouse brain, and suggests that this happens because exercise restores a brain chemical which promotes the production and maturation of new stem cells.   view more (2008-11-18)

Stress-related disorders affect brain's processing of memory
Researchers using functional MRI (fMRI) have determined that the circuitry in the area of the brain responsible for suppressing memory is dysfunctional in patients suffering from stress-related psychiatric disorders. Results of the study will be presented today at the annual meeting of the Radiological Society of North America (RSNA).   view more (2008-12-03)

A genetic basis for schizophrenia
Schizophrenia is a severely debilitating psychiatric disease that is thought to have its roots in the development of the nervous system; however, major breakthroughs linking its genetics to diagnosis, prognosis and treatment are still unrealized.   view more (2009-07-22)

MIT provides first evidence for learning mechanism
Finally confirming a fact that remained unproven for more than 30 years, researchers at MIT's Picower Institute for Learning and Memory report in the Aug. 25 issue of Science that certain key connections among neurons get stronger when we learn.   view more (2006-08-25)

Stem Cell Activity Deciphered in the Aging Brain
Neurobiologists have discovered why the aging brain produces progressively fewer new nerve cells in its learning and memory center. The scientists said the finding, made in rodents, refutes current ideas on how long crucial "progenitor" stem cells persist in the aging brain.   view more (2006-12-19)

Depression model leaves mice with molecular scar
In addition to triggering a depression-like social withdrawal syndrome, repeated defeat by dominant animals leaves a mouse with an enduring "molecular scar" in its brain that could help to explain why depression is so difficult to cure.   view more (2006-03-01)

Stress and nerve cells survival in rats; finding may open widow for depression treatment
A single, socially stressful situation can kill off new nerve cells in the brain region that processes learning, memory, and emotion, and possibly contribute to depression, new animal research shows.   view more (2007-03-14)

Growth hormone is made in the brain, report scientists
Scientists have found that growth hormone, a substance that is used for body growth, is produced in the brain, according to an article published in this week's Proceedings of the National Academy of Sciences.   view more (2006-03-28)

New Research Shows Why Too Much Memory May Be a Bad Thing
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 - making it harder to filter out information and increasing the time it takes... view more... (2007-03-30)

Fighting Sleep, Penn Researchers Reverse the Cognitive Impairment Caused By Sleep Deprivation
A research collaboration led by biologists and neuroscientists at the University of Pennsylvania has found a molecular pathway in the brain that is the cause of cognitive impairment due to sleep deprivation.   view more (2009-10-27)

'Speed of thought' guides brain's memory consolidation
Scientists at The University of Arizona have added another piece of the puzzle of how the brain processes memory.   view more (2007-11-16)

Immaturity of the brain may cause schizophrenia
The underdevelopment of a specific region in the brain may lead to schizophrenia in individuals. According to research published today in BioMed Central's open access journal Molecular Brain, dentate gyrus, which is located in the hippocampus in the brain and thought to be responsible for working memory and mood regulation, remained immature in an... view more...

Measuring brain atrophy in patients with mild cognitive impairment
Scientists at the University of California, San Diego School of Medicine have shown that a fully automated procedure called Volumetric MRI - which measures the "memory centers" of the brain and compares them to expected size - is effective in predicting the progression from mild cognitive impairment (MCI) to Alzheimer's disease.   view more (2009-06-17)

A fork in memory lane: UCSD research indicates hippocampus supports two aspects of recognition
Recollection, as defined by memory specialists, is the ability to call up specific details about an encounter, while familiarity is simply knowing that someone or something has been encountered before. Both are elements of recognition memory and both, new research suggests, are functions of the brain's hippocampus.   view more (2006-02-02)

Study finds how brain remembers single events
Single events account for many of our most vivid memories - a marriage proposal, a wedding toast, a baby's birth. Until a recent UC Irvine discovery, however, scientists knew little about what happens inside the brain that allows you to remember such events.   view more (2009-03-19)

Caltech scientists find evidence for precise communication across brain areas during sleep
By listening in on the chatter between neurons in various parts of the brain, researchers from the California Institute of Technology (Caltech) have taken steps toward fully understanding just how memories are formed, transferred, and ultimately stored in the brain--and how that process varies throughout the various stages of sleep.   view more (2009-02-26)

Adult neurogenesis newly adult-born neurons are functionally similar to mature neurons
In mammals, the production of new brain cells occurs primarily at the time the nervous system is developing, although certain brain areas generate neurons throughout adulthood. One such area is the hippocampus, a part of the brain involved in the critical function of memory and spatial perception.   view more (2006-11-21)

New MIT tool probes brain circuits
Researchers at the Picower Institute for Learning and Memory at MIT report in the Jan. 24 online edition of Science that they have created a way to see, for the first time, the effect of blocking and unblocking a single neural circuit in a living animal.   view more (2008-01-25)

How the brain weaves a memory
Memories of events comprise many components-including sights, sounds, smells, and tastes. Somehow the many features of an episodic memory are woven together into a coherent whole, and researchers have had little understanding of how this binding takes place as the memories are processed by the brain's memory center, the hippocampus.   view more (2006-11-09)

Brain cell growth diminishes long before old age strikes, animal study shows
Even early in adulthood, aging begins to slow the mind's growth -- but it does not have to stop it altogether, suggests a Princeton University study on the brains of adult monkeys.   view more (2007-10-16)
