Smoking thins vital part of brain

A major study by McGill University and the University of Edinburgh found that long-term smoking causes thinning of the brain's cortex, accelerating cognitive decline. Stopping smoking helps restore part of the cortex's thickness, but recovery is slow and incomplete.

No gain if unfair

A study found that humans tend to turn down sure rewards if they derive from an unfair distribution of resources, regardless of whether the individual themselves or others are affected. Brain imaging revealed differing brain circuits in these two conditions.

Graying, but still golden

Researchers found that older adults' acquired financial knowledge and experience can compensate for declining fluid intelligence, leading to more efficient financial decision-making. The study used credit scores and cognitive tests to demonstrate the importance of crystallized intelligence in finance.

Study shows cognitive training can improve brain performance of students in poverty

A study published in Frontiers in Human Neuroscience found that cognitive training can improve the brain performance of middle school students from poverty-stricken backgrounds. The program, called SMART, resulted in a 25% increase in gist reasoning and an 18% improvement in fact retention among students who received the training.

Where will big neuroscience take us?

Several countries have launched brain research projects with big budgets and ambitious goals, aiming to make groundbreaking discoveries and develop new treatments for diseases. The initiatives are expected to drive rapid progress in the field of neuroscience, with a focus on global collaboration and interdisciplinary approaches.

With rewards, we remember more than we should

A new study at Brown University found that reward overcomes retrieval-induced forgetting, a phenomenon where practicing certain facts suppresses recall of others. Volunteers who earned rewards during practice had improved recall of unpracticed fish category facts.

Finding 'lost' languages in the brain

Researchers at McGill University found that infant experiences shape the unconscious brain, influencing adult development even after years of disuse. The study used functional MRI scans to compare brain activation patterns in girls with unilingual French-speaking families versus those adopted from Chinese-speaking families.

Carving memories at their joints

A study published in PLOS Computational Biology proposes a theoretical framework for understanding memory formation and modification. The researchers suggest that large prediction errors lead to memory formation, while small errors result in memory modification. Damage to the hippocampus can impair the brain's ability to carve memories.

Identifying hidden minds in impaired consciousness

A study published in PLOS Computational Biology found that vegetative patients may have well-preserved brain networks similar to those of healthy adults, indicating possible covert awareness. This discovery could improve clinical assessment and help identify patients who might be aware despite being uncommunicative.

Kessler Foundation multiple sclerosis researchers find role for working memory in cognitive reserve

Researchers at Kessler Foundation found that working memory capacity explains the relationship between intellectual enrichment and long-term memory in individuals with MS. This suggests that interventions targeting working memory may help build cognitive reserve to protect against decline in long-term memory.

Understanding consciousness

Consciousness may be understood through scientific inquiry, despite current debates about its neural basis. Researchers argue that flawed assumptions about consciousness can be addressed through multiple scientific perspectives, potentially leading to breakthroughs in understanding human rights, disease treatment, and technology.

The whole truth

Researchers found that children can tell when adults are telling the truth but not the whole truth, and compensate by exploring more on their own. This skill is crucial for learning from others, as much knowledge comes from other people. Children's ability to evaluate information helps them adjust their trust in teachers.

Speaking 2 languages benefits the aging brain

A recent study published in Annals of Neurology found that individuals who speak two or more languages may experience slower cognitive decline and improved cognitive abilities later in life. The research controlled for childhood intelligence and showed a significant impact on general intelligence, reading, and other cognitive functions.

Outgrowing emotional egocentricity

Max Planck researchers identify supramarginal gyrus region crucial for children's ability to assess others' emotions, improving with age. The study reveals that adults can easily overcome egocentrism, whereas children between 6-13 tend to project their own emotions onto others.
