Studies have indicated that individuals who engage in mentally stimulating activities, such as learning a new language or playing a musical instrument, tend to have larger and more interconnected brain networks. This suggests that experience and environmental factors can impact brain size and structure.

Furthermore, age-related changes in brain size have been observed. It is well-documented that certain brain regions, such as the prefrontal cortex, tend to shrink with age.

However, this is not necessarily indicative of a decline in cognitive function. In fact, older individuals often compensate for these changes by recruiting other brain regions, allowing them to maintain cognitive abilities.

Interpreting Structural Changes in the Brain
