Varied life makes you smarter: A new study on how our experiences affect our intelligence

People who have been through a lot tend to be smarter - and now it's scientifically proven.

Researchers at the German Center for Neurodegenerative Diseases conducted a pioneering study that sheds light on how experiences leave their trace in the connectivity of the brain. 

Let's find out more.

A new experiment on how our experiences affect our brain

Using an innovative "brain-on-chip" technology with over 4,000 electrodes, the researchers discovered the massive effects of enriched experiences on large-scale neural networks and brain plasticity in mice. 

The study focused on the hippocampus, a brain structure critical for learning and memory, and known to be affected in neurodegenerative diseases like Alzheimer's. 

Comparing brain tissue from mice raised in standard cages and those in an "enriched environment" with stimulating toys and mazes, they found that the neurons of the latter group were much more interconnected, indicating that an active and varied life shapes the brain in novel ways.

This study offers unprecedented insights into brain networks and the impact of enriched experiences on neural circuitry, surpassing previous single electrode or imaging techniques. 

How it might help

The findings open avenues for understanding the role of plasticity and reserve formation in combating neurodegenerative diseases and developing preventive strategies. 

The research also has implications for brain-inspired artificial intelligence, as the insights into how experiences shape the brain's dynamics could lead to novel machine learning algorithms. 

This groundbreaking study brings us closer to understanding the complex interactions between experiences, brain plasticity, and neurological health, potentially influencing future treatments for neurodegenerative diseases.
