Newly discovered brain network offers clues to social cognition

By studying rhesus monkeys, researchers have identified a brain network dedicated to processing social interactions — a discovery that offers tantalizing clues to the origins of our ability to understand what other people are thinking.

Region in brain found to be associated with fear of uncertain future

People who struggle to cope with uncertainty or the ambiguity of potential future threats may have an unusually large striatum, an area of the brain already associated with general anxiety disorder, according to research.

How the injured brain tells the body it’s hurt

Researchers say they have identified a new way that cells in the brain alert the rest of the body to recruit immune cells when the brain is injured. The work was completed in mouse models that mimic infection, stroke or trauma in humans.

Exposure to BPA potentially induces permanent reprogramming of painted turtles’ brains

BPA is a chemical that is used in a variety of consumer products, such as food storage containers and water bottles. In previous studies, researchers determined that BPA can disrupt sexual function and behavior in painted turtles. Now, the team has identified the genetic pathways that are altered as a result of BPA exposure during early development.

Blind people have brain map for ‘visual’ observations too

Is what you’re looking at an object, a face, or a tree? When processing visual input, our brain uses different areas to recognize faces, body parts, scenes, and objects. Scientists have now shown that people who were born blind use a ‘brain map’ with a very similar layout to distinguish between these same categories.

Spread of tau protein measured in brains of Alzheimer’s patients

Researchers have measured how deposits of the pathological protein tau spread through the brain over the course of Alzheimer’s disease. Their results show that the size of the deposit and the speed of its spread differ from one individual to the next, and that large amounts of tau in the brain can be linked to episodic memory impairment.
