Genes and intelligence are actually connected: The new research

A groundbreaking study conducted by researchers from various institutions has shed light on the interplay between genes, brain characteristics, and behavior. 

While most people felt like these things are connected before, now we have scientific proof for that.

Let's find out more.

A new study

Examining a cohort of 557 participants, the study explored genetic variations associated with high intelligence, brain characteristics observed through scans, and performance in intelligence tests. 

The findings revealed that while numerous associations were found between genetic variations and brain characteristics, fewer connections were observed between brain characteristics and intelligence test performance. 

However, when all three parameters were considered, specific areas in the frontal, parietal, and visual cortex emerged as key regions where gene variations influenced brain characteristics that, in turn, affected intelligence. 

Characteristics that matter

The study suggests that the size of the brain surface and the efficiency of structural connectivity play crucial roles in this interplay. 

This methodology can be extended to other traits beyond intelligence, offering a comprehensive understanding of various characteristics. 

The researchers recommend conducting studies with larger cohorts to enhance the quality of results. 

Overall, this study represents a significant advancement in unraveling the complex connections between genetics, brain structure, and cognitive abilities, paving the way for further investigations in the field.
