A research group has succeeded in developing a gel material which is capable of releasing drugs in response to pressure applied by the patient.
New findings about how the brain functions to suppress pain have been published in the leading journal in the field Pain, by National University of Ireland Galway (NUI Galway) researchers. For the first time, it has been shown that suppression of pain during times of fear involves complex interplay between marijuana-like chemicals and other neurotransmitters in a brain region called the amygdala.
Researchers report that they have found a biological mechanism that appears to play a vital role in learning to read. This finding provides significant clues into the workings behind dyslexia — a collection of impairments unrelated to intelligence, hearing or vision that makes learning to read a struggle.
A new study suggests neural ‘synchrony’ may be key to understanding how the human brain perceives.
Sleep plays an important role in the brain’s ability to consolidate learning when two new potentially competing tasks are learned in the same day, research at the University of Chicago demonstrates.
New research for the first time explains exactly how two brain regions interact to promote emotionally motivated behaviors associated with anxiety and reward. The findings could lead to new mental health therapies for disorders such as addiction, anxiety, and depression.
Researchers have designed a decoded functional MRI neurofeedback method that induces a pre-recorded activation pattern in targeted early visual brain areas that could also produce the pattern through regular learning.
A new study conducted by monitoring the brain waves of sleeping adolescents has found that remarkable changes occur in the brain as it prunes away neuronal connections and makes the major transition from childhood to adulthood.
New research suggests that depression, even in children, can increase the risk of heart problems later in life. Teens who were depressed as children are far more likely than their peers to be obese, smoke cigarettes and lead sedentary lives, even if they no longer suffer from depression.
Alcohol consumption affects the brain in multiple ways, ranging from acute changes in behavior to permanent molecular and functional alterations. The general consensus is that in the brain, alcohol targets mainly neurons. However, recent research suggests that other cells of the brain known as astrocytic glial cells or astrocytes are necessary for the rewarding effects of alcohol and the development of alcohol tolerance.
New research published in The Journal of Neuroscience suggests that modifying signals sent by astrocytes, our star-shaped brain cells, may help to limit the spread of damage after an ischemic brain stroke.
The prefrontal cortex is a region of the brain that acts like a filter, keeping any irrelevant thoughts, memories and perceptions from interfering with the task-at-hand. In a new study, researchers have shown that inhibiting this filter can enhance unfiltered, creative thinking.
A new study suggests that depression results from a disturbance in the ability of brain cells to communicate with each other. The study indicates a major shift in our understanding of how depression is caused and how it should be treated.
