One common finding from these studies is that certain brain regions tend to be larger in individuals with higher cognitive abilities. For example, the prefrontal cortex, responsible for executive functions such as reasoning and decision-making, has been shown to be more extensive in individuals with advanced cognitive skills.
Additionally, neuroimaging studies have revealed that individuals with larger hippocampal volumes, a brain region associated with memory and learning, tend to perform better on memory-related tasks. These findings suggest that brain size may have some influence on cognitive abilities.
Experience and age altering brain size
While brain size is influenced by genetics, it is also subject to change throughout our lives. Both experience and age can shape the structure of the brain, offering further evidence of its plasticity.

Experience and age altering brain size
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
Examples of structural changes not correlated with improved function
While structural changes in the brain can be fascinating, it is important to note that not all changes lead to improved function. There have been instances where significant changes in brain structure do not necessarily translate into enhanced cognitive abilities.
