Key neural mechanism believed to support advanced cognitive abilities discovered

Scientists have discovered a neural mechanism that is believed to support advanced cognitive abilities such as planning and problem-solving.

Brain mechanisms involved in learning also drive social conformity

Some of the same brain systems known to play a role in learning from trial and error also are engaged when people conform to social norms, scientists report in a new study. The findings are important, the researchers said, because changing one’s behavi…

Face detection in untrained deep neural networks?

Researchers have found that higher visual cognitive functions can arise spontaneously in untrained neural networks. A research team has shown that visual selectivity of facial images can arise even in completely untrained deep neural networks. This new…

Autism-linked gene, if deleted, results in less myelin

In a new study, mice bearing a gene deletion associated with autism spectrum disorder (ASD) showed evidence of slower cognition. Another finding: cells that make myelin, a sheath around nerves that conducts electrical impulses quickly and efficiently, …

Wear and tear in vulnerable brain areas lead to lesions linked to cognitive decline

As our brains age, small lesions begin to pop up in the bundles of white matter that carry messages between our neurons. The lesions can damage this white matter and lead to cognitive deficits. Now, researchers not only provide an explanation for the l…

Visuals increase attention; now science explains why

Scientists report that norepinephrine, a fundamental chemical for brain performance, is locally regulated in a brain region called the visual cortex.

How the brain understands one voice in a noisy crowd

Researchers find that the brain is taking an extra step when listening to one speaker in a crowd, and not taking that step with the other words swirling around the conversation.

Pain and anxiety impact breathing on a cellular level

A team of scientists has uncovered a neural network in the brain that coordinates breathing rhythm with feelings of pain and fear. Along with contributions to the fields of pain management, psychological theories of anxiety, and philosophical investiga…

Rollercoaster of emotions: Exploring emotions with virtual reality

To the left and right, the landscape drifts idly by, the track in front of you. Suddenly, a fire. The tension builds. The ride reaches its highest point. Only one thing lies ahead: the abyss. Plummeting down into the depths of the earth. These are scen…

Research breakthrough could see HIV drugs used to treat low-grade brain tumors

Drugs developed to treat AIDS and HIV could offer hope to patients diagnosed with the most common form of primary brain tumor. The breakthrough is significant because, if further research is conclusive, the anti-retroviral drugs could be prescribed for…
