Patients in a new Northwestern Medicine study were able to comprehend words that were written but not said aloud. They could write the names of things they saw but not verbalize them. For instance, if a patient in the study saw the word 'hippopotamus' written on a piece of paper, they could identify a hippopotamus in flashcards. But when that patient heard someone say 'hippopotamus,' they could not point to the picture of the animal.
Oxford University researchers have discovered a brain process common to sleep and aging in research that could pave the way for new treatments for insomnia.
Adult depression has long been associated with shrinkage of the hippocampus, a brain region that plays an important role in memory and response to stress. Now, new research from Washington University in St. Louis has linked participation in team sports to larger hippocampal volumes in children and less depression in boys ages 9 to 11.
An international team of scientists at Indiana University School of Medicine, University of Kansas and the U.K. Medical Research Council have dismantled the belief that Alzheimer's disease and Chronic Traumatic Encephalopathy have made a discovery that offers options for improved diagnosis and potential targeted treatments.
A single allergic reaction during pregnancy prompts sexual-development changes in the brains of offspring that last a lifetime, new research suggests. Female rats born to mothers exposed to an allergen during pregnancy acted more characteristically 'male' -- mounting other female rodents, for instance -- and had brains and nervous systems that looked more like those seen in typical male animals.
Delusions are one of the most common symptoms of psychosis, but little is known about what causes them. A new study from researchers at Columbia University and New York State Psychiatric Institute offers insight into the development of delusions, which could lead to better treatments for people with psychosis.
In a front-cover paper published in Cerebral Cortex, EPFL's Blue Brain Project, a Swiss Brain Research Initiative, explains how the shapes of neurons can be classified using mathematical methods from the field of algebraic topology. Neuroscientists can now start building a formal catalogue for all the types of cells in the brain. Onto this catalogue of cells, they can systematically map the function and role in disease of each type of neuron in the brain.
An international study headed by researchers from Aarhus University has for the first time uncovered the large-scale brain patterns and networks in the brain which control sleep, providing knowledge which in the future may can in the long term help the many Danes large proportion of people who experience problems sleeping.
Participation in team sports is associated with fewer depressive symptoms in children, whereas non-sport activities have no association with symptoms, according to a study in Biological Psychiatry: Cognitive Neuroscience and Neuroimaging, published by Elsevier.
People with Alzheimer's disease using antiepileptic drugs have twice the risk of pneumonia compared to non-users, a new study from the University of Eastern Finland shows. The risk was highest in the beginning of use, but remained on an elevated level even in long-term use. The results were published in the Journal of Alzheimer's Disease.
