Brain-Wide Connections Predict Human Intelligence

A recent study explores how connections across the entire brain predict human intelligence, moving beyond traditional focus on specific brain areas like the prefrontal cortex. Using fMRI data from over 800 individuals, researchers analyzed communication between brain regions to predict fluid, crystallized, and general intelligence scores.

Huntington’s Gene Enhances Early Brain Growth and Intelligence

A study reveals that the genetic mutation causing Huntington’s disease (HD) enhances brain development and intelligence in early life, but leads to degeneration in adulthood. Children with the HD gene exhibit larger brains and higher IQs than those without the mutation.

Higher IQ in High School Linked to Increased Alcohol Use in Adulthood

A new study shows that individuals with higher IQs in high school are more likely to consume alcohol moderately or heavily later in life, though less likely to binge drink. This connection may be due to social factors, such as income level and career stress, that often accompany higher IQs. Researchers used data from the Wisconsin Longitudinal Study, revealing that each IQ point increase correlated with a 1.6% rise in moderate or heavy drinking.

Non-Cognitive Skills Are as Vital as Intelligence

A new study reveals that non-cognitive skills like motivation and self-regulation are as crucial as intelligence in determining academic success. These skills, influenced by both genetics and environment, grow increasingly important throughout a child's education.

Canine Cognition Unleashed: Dogs Exhibit Human-like Intelligence Factor

Dogs possess a 'g factor' akin to humans, illuminating the hierarchical structure of canine intelligence and its implications for aging. By evaluating 129 family dogs over two and a half years, the team identified broad cognitive domains—problem-solving and learning ability—that interlink to form a canine general cognitive factor.

How Genes, Brain Characteristics and Intelligence Are Connected

Using a combination of intelligence tests, genetic analysis, and neuroimaging data, researchers found there are only a few areas of the frontal, parietal, and visual cortices where gene variations influence brain characteristics which simultaneously influence intelligence.
