Researchers have revealed the molecular pathway that is affected during the onset of schizophrenia and successfully alleviated symptoms of the illness in mice, using a commonly used cancer drug.
The research, published online in the journal Brain, is from a group led by Professor Peter Giese at King's College London, and offers new avenues for drug discovery.
Taking a trip down memory lane while you are driving could land you in a roadside ditch, new research indicates. Vanderbilt University psychologists have found that our visual perception can be contaminated by memories of what we have recently seen, impairing our ability to properly understand and act on what we are currently seeing.
LA JOLLA, CA – Researchers at The Scripps Research Institute have developed a highly successful vaccine against a heroin high and have proven its therapeutic potential in animal models.
The new study, published recently online ahead of print by the American Chemical Society's Journal of Medicinal Chemistry, demonstrates how a novel vaccine produces antibodies (a kind of immune molecule) that stop not only heroin but also other psychoactive compounds metabolized from heroin from reaching the brain to produce euphoric effects.
Chalfont St. Giles, UK, July 20, 2011 - Recent clinical research data reported that the investigational amyloid imaging agent [18F]Flutemetamol showed highly consistent image interpretation1 and showed comparable in vitro binding to the Pittsburgh Compound-B ([C-11]PiB)) investigational imaging agent3. Flutemetamol is a GE Healthcare Positron Emission Tomography (PET) investigational imaging agent currently in phase III development being studied for the detection of beta amyloid using PET brain scans.
Inherited forms of Alzheimer's disease may be detectable as many as 20 years before problems with memory and thinking develop, scientists will report July 20, 2011, at the Alzheimer's Association International Conference on Alzheimer's Disease in Paris.
Identifying Alzheimer's in its earliest stages is a top priority for researchers. Many think that by the time symptoms become apparent, Alzheimer's disease has already damaged the brain extensively, making it difficult or impossible to restore memory and other mental abilities.
An existing anti-seizure drug improves memory and brain function in adults with a form of cognitive impairment that often leads to full-blown Alzheimer's disease, a Johns Hopkins University study has found.
Players of the game rock paper scissors subconsciously copy each other's hand shapes, significantly increasing the chance of the game ending in a draw, according to new research.
A study published today in the Proceedings of the Royal Society B shows that even when players lose out by drawing a game, they can't help themselves from copying the hand gestures of their opponent.
Scientists at the University of Liverpool have found that ancient footprints in Laetoli, Tanzania, show that human-like features of the feet and gait existed almost two million years earlier than previously thought.
Many earlier studies have suggested that the characteristics of the human foot, such as the ability to push off the ground with the big toe, and a fully upright bipedal gait, emerged in early Homo, approximately 1.9 million years-ago.
In the century and a half since Charles Darwin's publication of The Origin of Species, evolutionary theory has become the bedrock of modern biology, yet its application to the understanding of the human mind remains controversial. For the past 30 years, evolutionary interpretation of human cognition has been dominated by the field of evolutionary psychology.
Clocks tell time in numbers—and so do our minds, according to a new study which will be published in an upcoming issue of Psychological Science, a journal of the Association for Psychological Science. In two experiments, scientists found that people associate small numbers with short time intervals and large numbers with longer intervals—suggesting that these two systems are linked in the brain.
Attempts to recruit and retain more women in undergraduate engineering programs often lump all female students into a single group. At best, minority women as a group may receive special attention.
But a new study of female engineering students' perceived challenges finds significant differences between black, Hispanic, Native American, Asian-American and white women. The findings by researchers at University of Washington could help institutions better retain particular underrepresented groups of students.
Falls and balance problems may be early indicators of Alzheimer's disease, researchers at Washington University School of Medicine in St. Louis report July 17, 2011, at the Alzheimer's Association International Conference on Alzheimer's Disease in Paris.
Scientists found that study participants with brain changes suggestive of early Alzheimer's disease were more likely to fall than those whose brains did not show the same changes. Until now, falls had only been associated with Alzheimer's in the late stages of dementia.
The neurotransmitter dopamine is best known for its roles in the brain – in signaling pathways that control movement, motivation, reward, learning and memory.
EAST LANSING, Mich. — In a case of life imitating art, avian scents given off by male songbirds have the females (and males) flocking in.
Patients who use anti-depressants are much more likely to suffer relapses of major depression than those who use no medication at all, concludes a McMaster researcher.
In a paper that is likely to ignite new controversy in the hotly debated field of depression and medication, evolutionary psychologist Paul Andrews concludes that patients who have used anti-depressant medications can be nearly twice as susceptible to future episodes of major depression.
