TL;DR: The brain stores content (what you remember) and context (when/where) in separate neural populations linked by real-time coordination, not pre-wired conjunctive cells—a design that trades speed for flexibility, allowing you to recognize a friend’s face across any setting or apply a principle learned once to infinitely new situations. For forty years, neuroscientists thought memory …
Expert chess players use chunk memory to make better decisions, showing unique brain connectivity that helps them perform well even against tougher opponents. Highlights: Consistent Performance: Expert chess players perform equally well regardless of the difficulty level, unlike beginners whose performance drops with increased difficulty. Stronger Brain Connections: Experts show stronger connections in specific brain …
Student cognitive abilities and college institutional factors both shape outcomes, but the historical evidence suggests student characteristics play an outsized role. Key Facts: In the research paper, student cognitive aptitude accounted for 41-47% of the variance in long-term salary outcomes. Institutional factors collectively accounted for more variance when entered first into models, suggesting both student …
Education has long been thought to improve cognitive abilities like intelligence. But does simply spending more years in school actually make people smarter? A new meta-analysis of quasi-experimental studies provides compelling evidence that education significantly increases intelligence test scores, by as much as 1-5 IQ points for each additional year of education. Key Facts: Education …
A new study published in Scientific Reports provides insight into which memory training techniques are most effective at improving working memory. The research compared an adaptive n-back training task to the memory palace technique over 20 days of training. Both groups improved on trained tasks, but n-back training showed greater transfer to untrained working memory …
Researchers have for the first time reconstructed all neurons and their connections in the brain of a fruit fly larva, revealing fundamental principles of brain organization. The study provides an important scaffold for understanding the neural basis of behavior in this model organism. Key Facts: The larval Drosophila brain contains around 3000 neurons. The full …
Summary: A new study reveals how certain genes and education levels impact Alzheimer’s disease risk, even in individuals destined to develop dementia. Key facts: The APOE gene influences Alzheimer’s onset in people with a genetic mutation causing early-onset Alzheimer’s. Having APOE e4 accelerates onset of decline while APOE e2 delays it. More years of education …
