Differences in the neural wiring across development of men and women across ages, matched behavioral differences commonly associated with each of the sexes, according to an imaging-based study from researchers at the Perelman School of Medicine at the University of Pennsylvania published Feb. 1 in Philosophical Transactions of the Royal Society B.
Infant girls at risk for autism pay more attention to social cues in faces than infant boys, according to a Yale School of Medicine study -- the first one known to prospectively examine sex-related social differences in at-risk infants.
Certain chronic viral infections could contribute to subtle cognitive deterioration in apparently healthy older adults, according to a study led by researchers from the University of Pittsburgh and Johns Hopkins University.
In laboratory neuronal cultures, an FDA-approved drug used to treat high blood pressure reduced cell damage often linked to Alzheimer's disease, say researchers at Georgetown University Medical Center and the National Institutes of Health.
Researchers at the University of Pennsylvania's School of Engineering and Applied Science and Perelman School of Medicine are looking for ways to better pinpoint the anatomical source of seizures by looking at networks of electrical activity in the brain just prior to their onset.
A study out today sheds new light on multiple sclerosis, specifically damage in the brain caused by the disease that may explain the slow and continuous cognitive decline that many patients experience. The findings, which appear in the Journal of Neuroscience, show that the brain's immune system is responsible for disrupting communication between nerve cells, even in parts of the brain that are not normally considered to be primary targets of the disease.
Researchers have discovered that a social laboratory rodent, the prairie vole, shows an empathy-based consoling response when other voles are distressed. This is the first time researchers have shown consolation behavior in rodents, and this discovery ends the long-standing belief that detecting the distress of others and acting to relieve that stress is uniquely human.
A team of neurosurgeons and engineers has developed wireless brain sensors that monitor intracranial pressure and temperature and then are absorbed by the body, negating the need for surgery to remove the devices. Such implants, developed by scientists at Washington University School of Medicine in St. Louis and engineers at the University of Illinois at Urbana-Champaign, potentially could be used to monitor patients with traumatic brain injuries.
Analyzing brain scans of 105 children ages 7 to 12, researchers at Washington University in St. Louis have found that key structures in the brain are connected differently in poor children than in kids raised in more affluent settings. In particular, the brain's hippocampus -- a structure key to learning, memory and regulation of stress -- and the amygdala -- which is linked to stress and emotion -- connect to other areas of the brain differently in poor children than in those whose families had higher incomes.
A new study from Indiana University is the first to confirm that animals possess multiple 'working memory' systems, or the ability to remember more information across two categories versus a single category.
