Medical Xpress / Stress in adolescence causes lasting brain changes, suggests a study with mice
Stressful situations experienced during adolescence tend to cause deeper and more lasting changes to the brain than those experienced in adulthood. A study conducted on mice at the University of São Paulo (USP) in Brazil ...
Medical Xpress / Down syndrome study suggests early RNA editing shifts may reshape fetal brain circuits
A collaborative research study co-led by scientists at the Icahn School of Medicine at Mount Sinai and the Liber Institute for Brain Development has for the first time identified a biological process that may help explain ...
Medical Xpress / Blocking NOX-1 enzyme may extend ketamine's antidepressant effects
Treatment-resistant depression affects a large proportion of people with major depressive disorder, and while ketamine offers rapid relief, its antidepressant effects fade within a few weeks. Now, researchers from Japan have ...
Phys.org / Two-thirds of workers are burned out—here's what science says about how to tackle it
Burnout is at an all-time high, with some studies saying two-thirds of employees now cite job burnout as a major challenge. Overwork and chronic stress do not just drain energy, they can erode health, contributing to a wide ...
Medical Xpress / The brain region associated with moral inconsistency
Why don't some people practice what they preach? Researchers reveal that a brain region called the ventromedial prefrontal cortex (vmPFC) is involved. The researchers used fMRI imaging to identify brain activity patterns ...
Medical Xpress / How individual brain activity drives collective behavior
People may think of survival as an individual act—every animal (and person) for themselves. But a new study from UCLA suggests that when it comes to facing hardship together, social groups may function more like a unified ...
Medical Xpress / Gene mutation tied to schizophrenia slows brain's updating of beliefs
One of the symptoms of schizophrenia is difficulty incorporating new information about the world. This can lead patients to struggle with making decisions and, eventually, to lose touch with reality. MIT neuroscientists have ...
Medical Xpress / What happens to your brain in nature? The neuroscience explained
Have you ever felt calmer almost as soon as you step into the woods? Or maybe noticed your busy mind soften as you look out at the sea?
Medical Xpress / Gene expression program linked to neurotransmission in the living human brain identified
Researchers have identified a distinct and reproducible gene expression program associated with neurotransmission in the living human brain, offering unprecedented insight into the molecular mechanisms that support human ...
Medical Xpress / Brain scans reveal link between thinner brain cortex regions and higher psychopathic traits
A team of researchers from Spain was curious to know if people with high psychopathic traits have anomalies in the brain's physical structures, which make them incapable of feeling regret or capable of manipulation and other ...
Medical Xpress / Why anger feels close to fear: Brain charts emotion in a map-like way
It is well established in psychology that humans conceptualize emotions by features known as valence (the degree of pleasantness or unpleasantness) and arousal (the intensity of bodily reactions, such as rapid breathing or ...
Medical Xpress / PV inhibitory neurons, not overall prefrontal cortex decline, linked to cocaine-seeking relapse
Drug addiction carries an extremely high risk of relapse, as cravings can be reignited by minor stimuli even long after one has stopped using. Previously, this phenomenon was attributed to a decline in the function of the ...
