A Rutgers University, Newark and Collége de France, Paris research team has pinpointed for the first time the mechanism that takes place during sleep that causes learning and memory formation to occur.
NEW YORK - In the first functional magnetic resonance imaging (fMRI) study of its kind, neurologists and psychiatrists at Columbia University have identified an area of the
brain involved in the earliest stages of schizophrenia and related psychotic disorders.
A newly designed computational method has proven its usefulness in counting copies of duplicated genome sequences and in doing initial assessments of their contents, according to a study to be published Aug. 30 in Nature Genetics. The number of copies of particular DNA segments can differ from one person to the next.
CAMBRIDGE, Mass. -- 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.
The work will appear in the Aug. 27 issue of the journal Neuron.
The observation that people taking medication for schizophrenia have lower cancer rates than other people has prompted new research revealing that anti-psychotic drugs could help treat some major cancers.
CHICAGO --- Schizophrenia waits silently until a seemingly normal child becomes a teenager or young adult. Then it swoops down and derails a young life.
Scientists have not understood what causes the severe mental disorder, which affects up to 1 percent of the population and results in hallucinations, memory loss and social withdrawal.
The number of people killed by individuals suffering from mental illness in England and Wales increased between 1997 and 2005, figures released today show. The rise occurred in people who were not under mental health care and was not found in mental health patients.
Similarities in brain activity during lucid dreaming and psychosis suggest that dream therapy may be useful in psychiatric treatment, a European Science Foundation (ESF) workshop has found. This is strengthened by the potential evolutionary relationship between dreams and psychosis.
It is widely known that the brain perceives information before it reaches a person's awareness. But until now, there was little way to determine what specific mental tasks were taking place prior to the point of conscious awareness.
In the brain, many types of synaptic proteins are spatio-temporally regulated to maintain synaptic activity at a constant level. Here, the Japanese research group led by Professor Masaki Fukata, Drs.
New Orleans, LA -- For the first time, an international group of researchers has found genetic evidence linking schizophrenia to a specific region of DNA -- on chromosome 6. This is the same area where key genes for immune function are located.
CHICAGO --- John Csernansky wants to take your measurements. Not the circumference of your chest, waist and hips. No, this doctor wants to stretch a tape measure around your hippocampus, thalamus and prefrontal cortex.
Although the tiny roundworm Caenorhabditis elegans has only 302 neurons in its entire nervous system, studies of this simple animal have significantly advanced our understanding of human brain function because it shares many genes and neurochemical signaling molecules with humans. Now MIT researchers have found novel C.
Pediatric researchers have identified hundreds of gene variations that occur more frequently in children with attention-deficit hyperactivity disorder (ADHD) than in children without ADHD. Many of those genes were already known to be important for learning, behavior, brain function and neurodevelopment, but had not been previously associated with ADHD.
Stressful life events are strongly associated with a person's risk for major depression, but a certain gene variation long thought to increase risk in conjunction with stressful life events actually may have no effect, according to researchers funded by the National Institute of Mental Health (NIMH), part of the National Institutes of Health.
