Cortical representations for the sounds and meanings of new words learned form within an hour or two following exposure.
Neuroimaging pinpoints areas of the brain that regulate efforts to deal with fatigue. The study reveals the neural mechanisms that contribute to feelings of fatigue.
Coercion to perform detrimental actions against others reduces empathy and guilt, a new study reports. The findings may explain why people are able to commit immoral acts that go against their ethical stance when coerced.
Using chemogenetic methods, researchers activated neurons in the anterior insular and increased prosocial behavior in rodent models of opioid addiction.
Three months of transcendental meditation reduced anxiety and resulted in marked changes in connectivity between the precuneus, left parietal lobe, and insula.
Reduced gray matter volume in the insula and dorsolateral prefrontal cortex may represent a genetically conferred predispositional risk factor for alcohol use disorder.
White matter tracts show increasing maturation with age from the back to the front of the brain. The maturations begin as a child reaches 9-12 years of age. The maturity correlates with a critical and formative period of development.
Stress can have an impact on voice disorders. Researchers found those with higher salivary cortisol levels also exhibited brain activity that impacted the larynx. Those who were more introverted were more likely to have stress reactions related to speech.
People with higher levels of depressive moods exhibited heightened sensitivity to pain, and had greater activation in the prefrontal cortex, insula and somatosensory cortex.
