Medical Xpress / A possible chemical explanation for why we give up on tough tasks
When we engage our brains in a mentally taxing task, we eventually reach a point where we hit a wall or run on empty. Even when the rewards of finishing are obvious, we often find ourselves simply stopping. Exactly why this ...
Medical Xpress / In parallel mouse studies, researchers fail to replicate many reported effects of psilocybin
Experimental trials of psychedelic drugs in both humans and animals have produced conflicting results, creating doubts about whether hallucinogens have a therapeutic role in treating neurologic or behavioral disorders such ...
Medical Xpress / Brain scans challenge link between prefrontal activity and ability to regulate emotions
A person's capacity to regulate their emotions apparently cannot be determined by the activity of the prefrontal brain regions typically associated with this process. This is shown by an international fMRI analysis conducted ...
Medical Xpress / Mindfulness-based therapy may reshape brain responses to opioid cues during addiction treatment
Mindfulness-Oriented Recovery Enhancement (MORE), a behavioral therapy used alongside medication treatment, may help people with opioid use disorder respond differently to drug-related cues and natural rewards, according ...
Medical Xpress / Small deep brain structure may play major role in sustaining working memory, mouse experiments suggest
Reading a sentence, following a conversation, solving a problem or deciding what to do next: all of these rely on working memory. It allows the brain to hold information in mind for a few seconds, even after the stimulus ...
Medical Xpress / Detailed brain map reveals how the insula shapes bodily sensations and processes pain
Tucked deep within the human brain's lateral fissure, beneath layers of the cerebral cortex, lies the insula. It is the hub that controls sensations ranging from pain and physical touch to hunger and emotions. Yet, it remains ...
Medical Xpress / Wireless neural chip tracks brain changes in real time after Alzheimer's drug administration
A joint research team led by KAIST has used a small, implantable neural chip to wirelessly monitor real-time changes in a neurotransmitter involved in memory and learning after an Alzheimer's drug has been administered. In ...
Phys.org / Crows make decisions twice as fast as humans and monkeys
University of Tübingen researchers have shown that crows, when confronted with a visual choice, make a decision twice as fast as humans and monkeys. In the experiment, two carrion crows took just 235 milliseconds on average ...
Medical Xpress / ADHD medications offer promise in managing menopausal brain fog
An estimated 44% to 60% of perimenopausal women report cognitive changes like forgetfulness and trouble concentrating—also known as brain fog. Despite the effect of these symptoms on quality of life and productivity, there ...
Medical Xpress / Same 'sad' body movements, opposite brain responses: Study reveals differences by depressive symptom level
Previous studies have suggested that body posture and movement can influence emotions. KAIST researchers have extended this line of research by showing that when people perform the same "depressed" body movements, their brain ...
Medical Xpress / VR tours of gardens suggest well-designed natural spaces can deliver restorative health benefits
Some of nature's healthful benefits might be possible through well-curated ornamental spaces, suggests a brain activity study recently published in the October issue of Building and Environment from researchers at Drexel's ...
Medical Xpress / Gut microbes from people with schizophrenia alter mouse behavior
Researchers at the University of Coimbra in Portugal recently investigated whether gut microbes from people with schizophrenia could affect behavior and immune activity in mice. Their findings, published in Translational ...
