How some older brains decline before people realize it
Structural and functional alterations in the cognitive control network contribute to individual variability in memory performance during aging.... Read More...
Frog in your throat? Stress might be to blame for vocal issues
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.... Read More...
Brain region linked to altered social interactions in autism model
The anterior cingulate cortex (ACC) plays a critical role in regulating social behaviors. In mouse models of ASD, dysfunction in the ACC was linked to social impairments associated with the disorder.... Read More...
Seeing disfigured faces prompts negative brain and behavior responses
Neuroimaging reveals people experience a diminished neural response in the anterior cingulate cortex when shown images of others with facial disfigurements. A similar response is also seen when people view other stigmatized people, such as those who are homeless. The diminished activity may explain why people are less empathetic toward those who have facial disfigurements and may help explain the underlying neural mechanism for dehumanization. ...

Brain changes in autism traced to specific cell types
Studying brain tissue samples from people with ASD revealed a common set of alterations in genes associated with synaptic communication between neurons. The changes were identified mainly in neurons in the uppermost layers of the neocortex. ... Read More...
How we make complex decisions
When making complex decisions, the brain performs two computations using distributed network areas in the frontal cortex. ... Read More...
Broccoli sprout compound may restore brain chemistry imbalance linked to schizophrenia
Sulforaphane, a compound derived from broccoli sprouts, may be a useful new treatment for those suffering from schizophrenia. In a recent set of animal and human studies, researchers characterized novel chemical imbalances in the brain related to glutamate. Levels of glutamate, they discovered, can be altered by administering sulforaphane.... Read More...
Brain scans on movie watchers reveal how we judge people
Using a combination of movie clips and neuroimaging, researchers find people have positive biases to those they feel are more like them, even if they are unable to see the person's face.... Read More...
Haunted by the past: Insomniacs unable to get emotional distress off their mind
For some, insomnia may be caused by failing to neutralize emotional distress. Researchers speculate the sleep disorder could be caused by brain circuits that regulate emotion. ... Read More...
Low-intensity ultrasound can change decision-making process in the brain
A study of macaque monkeys reveals low-intensity ultrasound can both generate and suppress signalling in the brain and modulate normal function. The ultrasonic stimulation alters counterfactual thinking, allowing the ability to decide upon a better alternative in decision-making tasks.... Read More...
I feel you: Emotional mirror neurons found in the rat
Study reports the anterior cingulate cortex of rats contain mirror neurons that respond to pain experienced by and observations of others.... Read More...
