Changes in areas of the brain associated with emotion have been identified in people with Takotsubo syndrome, sometimes known as broken heart syndrome, according to new research.
A research team in Spain and the US has created 3D-printed acoustic holograms to improve the treatment of diseases like Alzheimer's and Parkinson's, among others.
Two clusters of brain cells compete to promote either the persistence or disappearance of traumatic memories, according to a new study conducted in mice. The findings could provide important insights into human conditions such as post-traumatic stress disorder (PTSD), anxiety disorders, and associated problems such as alcohol use disorder (AUD) that can arise from the persistence of traumatic…
A research team from the Institut de Neurociències at the Universitat Autònoma de Barcelona (INc-UAB) has showed that inhibition through a drug of the Tac2 neuronal circuit, involved in the formation of the memory of fear, has opposite effects on the ability to remember aversive events in mice according to sex: it is reduced in male mice and increased in female mice.
Over-activity in a single brain region called the subgenual anterior cingulate cortex (sgACC) underlies several key symptoms of mood and anxiety disorders, but an antidepressant only successfully treats some of the symptoms. A new study suggests that sgACC is a crucial region in depression and anxiety, and targeted treatment based on a patient's symptoms could lead to better outcomes.
Scientists have identified mechanisms in the human brain that could help explain the phenomenon of the 'Uncanny Valley' - the unsettling feeling we get from robots and virtual agents that are too human-like. They have also shown that some people respond more adversely to human-like agents than others.
A recently recognized brain disorder that mimics clinical features of Alzheimer’s disease has for the first time been defined with recommended diagnostic criteria and other guidelines for advancing and catalyzing future research. Scientists from several National Institutes of Health-funded institutions, in collaboration with international peers, described the newly-named pathway to dementia,…
New research from the Westmead Institute for Medical Research and the University of Sydney has found that neurons deep inside the brain could hold the key to accurately diagnosing bipolar disorder and depression.
Clinicians should consider how the way we think can make us vulnerable to obesity, and how obesity is genetically intertwined with brain structure and mental performance, according to new research. The study, led by researchers at the Montreal Neurological Institute and Hospital (The Neuro), was an examination of MRI and cognitive test data from 1,200 individuals, supplied as part of the Human…
A team of neurobiologists has identified a novel neuronal circuit in the midbrain that gates fear learning. They think that associative learning of fear is mediated by a novel dopamine circui.
New information on dementia biomarkers is emerging, as increasing results from population studies become available. However, although the list of risk factors lengthens, the value of these predictors, and more generally the cause of disease, remain to be determined, according to Gabriel Krestin, professor and chairman of the Department of Radiology & Nuclear Medicine at Erasmus MC, University…
Retrograde amnesia is the inability to recall established memories. In humans, amnesia is associated with traumatic brain injury, Alzheimer’s disease, and other neurological conditions. Whether memories lost to amnesia are completely erased or merely unable to be recalled remains an open question. Now, in a finding that casts new light on the nature of memory, researchers from the RIKEN-MIT…
Fructose not only results in a lower level of satiety, it also stimulates the reward system in the brain to a lesser degree than glucose. This may cause excessive consumption accompanied by effects that are a risk to health, report researchers from the University of Basel in a study published in the scientific journal PLOS ONE. Various diseases have been attributed to industrial fructose in…
A group of passengers who thought they were going to die when their plane ran out of fuel over the Atlantic Ocean in August, 2001 have had their brains scanned while recalling the terrifying moments to help science better understand trauma memories and how they are processed in the brain.
How the brain changes with age is not well-characterized and even less is known about the factors influencing the rate of brain aging. Brain imaging can offer a window into risk assessment into for diseases such as Alzheimer’s disease. A recent study demonstrated that genetic risk is expressed in the brains of even those who are healthy, but carry some risk for AD.
Andrea Martini and Joerg Larsen, of the Institute for Roentgendiagnostics, Braunschweig Teaching Hospitals, Germany, discuss nanotechnology, hybrid imaging and the quest for a personalised medicine.
The Uliazpi Foundation in Spain, which studies and cares for severely mentally retarded patients, carried out an interesting study to identify bone mineral density values in a group of its patients, compare these with the general population and investigate the possible influence on these values on certain clinical variables and therapeutic regimens.
Functional MRI (fMRI) is a widely used method capable of mapping functional regions of the human cortex in near real time during specific tasks.
