People with prosthetic arms or hands do not experience the 'size-weight illusion' as strongly as other people, new research shows.
Neuroscientists have charted the incoming and outgoing connections of a brain region located deep within the monkey prefrontal cortex that has important roles in emotion and memory processes. The comprehensive, high-resolution map reported in JNeurosci provides new insight into how emotional regulation may become disrupted in psychiatric disorders.
Major beer companies have rolled out marketing campaigns and products -- such as 'fan cans,' store displays, and billboard ads -- that pair beer with university colors, mascots, and logos. Research published in the January 2018 issue of Psychological Science shows that such campaigns may enhance the motivational significance of marketed beer brands, especially for students who identify strongly with their university. The researchers conclude that this effect could potentially increase underage students' alcohol consumption.
A new study in Biological Psychiatry has characterized the patterns of brain neurotransmitters glutamate and GABA in a network of regions that temporarily maintain and process visual information about the location of objects in space, a cognitive ability referred to as visuospatial working memory. The study reports that the patterns are altered in people with schizophrenia, suggesting a potential explanation for the impairments in visuospatial working memory that characterize people with the disorder.
Confirming earlier computational models, researchers at University of California San Diego and UC San Diego School of Medicine, with colleagues in Arizona and Louisiana, report that episodic memories are encoded in the hippocampus of the human brain by distinct, sparse sets of neurons.
A new study led by researchers at Indiana University and Rutgers University provides the strongest evidence yet that nearly imperceptible changes in how people move can be used to diagnose neurodevelopmental disorders, including autism.
Among other benefits, breast milk contains natural sources of prebiotics: small, indigestible fiber molecules that promote the growth of good bacteria in the baby's gut. Yet for many families, breastfeeding is difficult or impossible. Fortunately, modern infant formulas are getting closer to the real thing with the help of University of Illinois researchers.
Recording brain activity via electrodes placed directly on the cortical surface (ECoG) provides much clearer views of thinking activity and how the prefrontal cortex coordinates the brain's response to a perception. With the help of 16 epilepsy patients, UC Berkeley neuroscientists tracked the brain's activity as it detects, interprets, settles on a response and activates motor areas to respond. The brain prepares to respond very early, even before we know how we will respond.
Two independent teams of scientists from the University of Utah and the University of Massachusetts Medical School have discovered that a gene crucial for learning, called Arc, can send its genetic material from one neuron to another by employing a strategy commonly used by viruses. The studies, both published in Cell, unveil a new way that nervous system cells interact.
An increasing number of older adults are reporting cognitive impairment in their families over the past two decades, according to a new study led by researchers at NYU Rory Meyers College of Nursing and East Carolina University's Brody School of Medicine.
