A team of scientists has developed an algorithm that can accurately pinpoint, in large regions of the human genome, mutations favored by natural selection. The finding provides deeper insight into how evolution works, and ultimately could lead to better treatments for genetic disorders.
Researchers at Columbia University Irving Medical Center (CUIMC) and New York State Psychiatric Institute (NYSPI) found that people with schizophrenia who experience auditory hallucinations tend to hear what they expect, an exaggerated version of a perceptual distortion that is common among other people without hallucinations.
Pain is essential for survival. However, it could also slow the progress of rehabilitation, or in its chronic form could become a distinct disorder. How strongly we feel it, among other factors, depends on our individual pain threshold. Scientists at the Max Planck Institute for Human Cognitive and Brain Sciences (MPI CBS) in Leipzig discovered that a new fitness method they developed increases our pain threshold and makes us less sensitive towards physical discomfort: Jymmin interacts with everyday gym equipment to produce music while exercising.
Study finds engaging young children in conversation is more important for brain development than “dumping words” on them.
Lesbian and gay youth showed significantly less psychological distress and were buffered against the negative effects of bullying and victimization when they were in a relationship than when they were not, reports a new Northwestern Medicine study conducted in collaboration with the University of Cincinnati.
A team of researchers at the University of Georgia’s Regenerative Bioscience Center and ArunA Biomedical, a UGA startup company, have developed a new treatment for stroke that reduces brain damage and accelerates the brain’s natural healing tendencies in animal models. They published their findings in the journal Translational Stroke Research.
New Perceptual Pathway Identified That Can Lead To Body Size Misperception and Increase Risk of Eating and Exercise Disorders
New study identifies a perceptual pathway that can lead to body size and shape misperception in individuals. Those who are less satisfied with their bodies tend to look longer, and more often, at thin compared to fat bodies, causing visual mechanisms in their brains to adapt, making thinner bodies look “normal”
A new study in mice suggests that a burst of dopamine levels at the beginning of a movement only, as opposed to all the time, is what gets us going. This may have important implications for treating Parkinson’s disease.
Columbia and UCSF neuroscientists have found, in mice, that certain cells fire when the animal is anxious, triggering anxiety-related behaviors.
While most treatments for Alzheimer’s disease focus on improving memory, researchers at The Ohio State University Wexner Medical Center conducted a study aimed at slowing the decline of problem solving and decision-making skills in these patients.
