Homeostasis is the property of a system in which variables are regulated so that internal conditions remain stable and relatively constant. The human body manages a multitude of highly complex … Continue Reading Neuroimaging identifies previously unknown circuitry in brain homeostasis.
Alzheimer’s disease is a progressive illness that is the leading cause of dementia and the sixth leading cause of death in the United States. There is no cure for the … Continue Reading Neuroimaging links two Alzheimer’s risk genes to brain atrophy, promising blood markers.
Internet gaming disorder (IGD) is defined as a failure to control one’s impulses to excessively use online gaming. IGD results in serious negative outcomes, such as decreased physical and mental … Continue Reading Neuroimaging identifies brain differences in compulsive video game players.
Currently, more than 6 million children in the United States, or 11% of all children aged 4 to 17, have received attention-deficit hyperactivity disorder (ADHD) diagnoses. The disorder is characterized … Continue Reading Neuroimaging shows interactions in attention-based brain networks weaker in children with ADHD.
Obesity is a significant risk factor for cardiovascular disease, diabetes, and cancer. Although obesity can stem from behavioural factors such as diet and physical inactivity, central nervous system changes can … Continue Reading Neuroimaging maps areas of the brain in obese children activated by food odours.
Differences in the size and structure of certain brain areas have been found in some adults diagnosed with schizophrenia. Early findings came from the discovery of enlarged ventricles in people … Continue Reading Neuroimaging matches specific schizophrenia behaviour to the brain’s anatomy.
Air pollution is a serious public health issue and exposures to concentrations of air pollutants at or above the current standards has been linked to neuroinflammation and neurodegeneration. In the … Continue Reading Study shows that air pollution has detrimental impact on Alzheimer’s risk gene.
Many diseases involve structural changes in tissues, which are reflected in a change in their mechanical properties, such as elasticity. Using the sensitivity of their hands, and their detailed knowledge … Continue Reading Researchers have developed non-invasive palpation for the brain.
In their everyday life, people are constantly confronted with decision conflicts, especially if they need to suppress an action that would have made sense under normal circumstances. For example, when … Continue Reading Neuroimaging shows that the human hippocampus is involved in quick and successful decisions.
A blood clot is a dangerous health situation with the potential to trigger heart attacks, strokes and other medical emergencies. To treat a blood clot, doctors need to find its … Continue Reading New contrast allows whole-body blood clot scans in animal model.
Examining post-mortem tissue from the brains of people with Alzheimer’s disease, Stanford University researchers state they have identified what appear to be iron-containing microglia, specialized scavenger cells that sometimes become … Continue Reading A human study identifies region specific iron-containing microglia in Alzheimer’s brains.
Researchers at Columbia University and Washington University have found that key parts of the human brain network that give a person the power to control and redirect their attention, a … Continue Reading Researchers identify previously unknown human-specific attention network in the brain.
Some common themes are beginning to emerge from research on structural and functional brain connectivity in autism spectrum disorders (ASD). However, much more work will be needed to learn how … Continue Reading Multiple neuroimaging studies point to brain connectivity changes in autism.
For 140 years, scientists’ understanding of language comprehension in the brain came from individuals with stroke. Based on language impairments caused by stroke, scientists believed a single area of the … Continue Reading Researchers map new area of language in the human brain.
