Both the default mode network and salience network in superagers had stronger connectivity than typical older adults and similar connectivity as younger adults. Superagers performed similarly to young adults and better than typical older adults in recognition and episodic memory tasks.
Obesity risk in teens appears to be associated with stronger connectivity within and between regions of the brain implicated in determining the salience of stimuli. This may have implications for reward processing. Researchers report executive control efforts in the brain decrease when salience and reward-processing regions are engaged in teens with obesity.
A new meta analysis study identifies dysfunction of neurocognitive networks across multiple psychiatric disorders.
Findings about how early life social stress affect brain connections in mice may have implications for treating human psychiatric illnesses.
Corporal punishment may detrimentally harm brain development, a new study reports. Previous studies have revealed links between spanking and psychological problems, including depression and anxiety. The new study found children who experienced spanking as a form of punishment demonstrated greater activation in areas of the prefrontal cortex in response to fearful stimuli.
A new study reports Alzheimer's disease does not appear to affect the salience network. Researchers found, when listening to music, the salience network along with other networks, show higher functional connectivity in Alzheimer's patients.
Music specially composed for preterm babies helps strengthen the development of neural networks and may help to limit neurodevelopmental delays often experienced by those born prematurely.
Researchers report those who enter into an altruistic act, such as donating a kidney to an anonymous recipient, are more sensitive to a stranger's fear and pain.
New research suggests the high relapse rate in smokers could be explained by diminished connectivity in key brain networks.
