Resolving ambiguity: How the brain uses context in decision-making and learning

Life can be tricky. We have so many decisions to make. It’s a good thing we have an orbitofrontal cortex and hippocampus to help us. These areas of the brain work together to help us sort through tasks that require resolving ambiguity, that is, situati…

When does waiting stop being worth it?

Psychologists looked at individuals with damage to different parts of the prefrontal cortex to reveal how the brain evaluates uncertainty and guides split-second decisions.

Sculpting the brain (without chisel or scalpel)

Researchers report that they have successfully tested a novel approach for teaching the human brain to learn through external manipulation and neural feedback — what they call the ‘sculpting’ of brain activity patterns.

Researchers ‘see’ vulnerability to gaming addiction in the adolescent brain

Researchers found that adolescents with more symptoms of gaming addiction showed lower brain activity in the region involved in decision-making and reward processing; this blunted response to reward anticipation is associated with higher symptoms of ga…

‘Missing link’ between brain and body inflammatory signals identified in the skull

New research provides valuable insights into the brain-body immune connection identifying key communication hubs in the dural sinuses and skull bone marrow at the back of the head.

Fetal defense: Study reveals early immune protection in the womb

Research revealed that foetuses are not as defenceless as once thought; they can actually fight infections from within the womb. This new understanding could significantly change the way doctors protect foetuses from infections that lead to serious hea…

Study helps solve mystery between repeated head impacts in sports and location of brain degeneration in CTE

A new study is helping solve the mystery as to why the brain shrinks in a unique pattern, known as atrophy, in chronic traumatic encephalopathy (CTE). This research provides novel evidence that cumulative repetitive head impacts are driving the specifi…

Early detection of high-altitude hypoxic brain injury

People who climb too fast or too high risk acute altitude sickness, which can lead to life-threatening hypoxic brain injury. By using in vivo electrochemistry, researchers demonstrated that characteristic changes occur in the oxygen content of various …

New brain mapping technique reveals insights into the brain’s higher functions

A new way of mapping activity and connections between different regions of the brain has revealed fresh insights into how higher order functions like language, thought and attention, are organized.

Molecular zip code draws killer T cells straight to brain tumors

Scientists have developed a ‘molecular GPS’ to guide immune cells into the brain and kill tumors without harming healthy tissue.
