Researchers get closer to preventing Alzheimer's disease
A recent study directed by Mount Sinai School of Medicine identifies a faulty molecule in the brain found in cases of mild cognitive impairment (MCI). view more (2006-07-06)
New mouse model of depression/anxiety enhances understanding of antidepressant drugs
A recent study finds that the antidepressant effects of drugs like Prozac involve both neurogenesis-dependent and -independent mechanisms, a finding that may lead to development of better treatments for depression and anxiety. view more (2009-05-28)
Microscopic brain imaging in the palm of your hand
Researchers at Stanford University have demonstrated a promising, minimally invasive optical technique that can capture micron-scale images from deep in the brains of live subjects. view more (2005-08-25)
Healthy older brains not significantly smaller than younger brains, new imaging study shows
The belief that healthy older brains are substantially smaller than younger brains may stem from studies that did not screen out people whose undetected, slowly developing brain disease was killing off cells in key areas, according to new research. As a result, previous findings may have overestimated atrophy and underestimated normal size for the... view more... (2009-09-08)
How seizures progress to epilepsy in the young
A major mystery in epilepsy research has been why infants are more prone to seizures than adults and how those seizures progress to chronic epilepsy. view more (2005-12-08)
Microscopic brain damage detected in early Alzheimer's disease
Researchers have developed a new computer-aided analysis technique to identify early cellular damage in Alzheimer's disease (AD). view more (2006-09-26)
Researchers uncover mechanisms of common inherited mental retardation
Researchers at UT Southwestern Medical Center are uncovering how brain cells are affected in Fragile X syndrome, the most common cause of inherited mental retardation and the most common genetic cause of autism. view more (2008-01-09)
Rats' mental 'instant replay' drives next moves
Researchers at MIT's Picower Institute for Learning and Memory have found that rats use a mental instant replay of their actions to help them decide what to do next, shedding new light on how animals and humans learn and remember. view more (2009-08-27)
Mice with defective memory may hold clues to schizophrenia
By deleting a single gene in a small portion of the brains of mice, researchers at UT Southwestern Medical Center found that the animals were affected in a way resembling schizophrenia in humans. view more (2006-01-18)
UNC study ties ending moderate drinking to depression
Scientific evidence has long suggested that moderate drinking offers some protection against heart disease, certain types of stroke and some forms of cancer. view more (2008-07-09)
'Smart' mice teach scientists about learning process, brain disorders
Mice genetically engineered to lack a single enzyme in their brains are more adept at learning than their normal cousins, and are quicker to figure out that their environment has changed, a team led by researchers at UT Southwestern Medical Center has found. view more (2007-05-29)
Brain's reward circuit activity ebbs and flows with a woman's hormonal cycle
Fluctuations in sex hormone levels during women's menstrual cycles affect the responsiveness of their brains' reward circuitry, an imaging study at the National Institute of Mental Health (NIMH), a component of the National Institutes of Health (NIH), has revealed. view more (2007-02-05)

New discoveries about neuron plasticity linked to learning and memory
Neurons experience large-scale changes across their dendrites during learning, say neuroscientists at The University of Texas at Austin in a new study that highlights the important role that these cell regions may play in the processes of learning and memory. view more (2005-11-02)
Mutant mice show key autism traits
While the causes of autism remain complex and mysterious, researchers are steadily adding pieces to its intricate puzzle. view more (2006-05-04)
Dogma Destroyed: "Neural Glue" Can Communicate!
For a long time glyacytes were merely regarded as a kind of glue which fills up the extra-cellular space in the brain and stabilises the nerve cells. However, researchers from the University of Bonn, together with their Swiss colleagues, have been able to prove convincingly for the first time that this "neural glue" is more communicative... view more...

How to build a bigger brain
Push-ups, crunches, gyms, personal trainers - people have many strategies for building bigger muscles and stronger bones. But what can one do to build a bigger brain? view more (2009-05-13)
Researchers reveal how the brain processes important information
Researchers at UT Southwestern Medical Center have shed light on how the neurotransmitter dopamine helps brain cells process important information. view more (2009-04-03)
Blood pressure drug curbs brain damage from PTSD
A drug used to treat high blood pressure and enlargement of the prostate may protect the brain from damage caused by post-traumatic stress disorder, Alzheimer's disease, depression and schizophrenia. view more (2007-11-07)
'Memory molecule' stores memories in neocortex
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, New York. view more (2007-08-17)
