: The prefrontal cortex (responsible for rational thinking) stops growing at age 25. Does that mean that one’s ability to conduct a complex reasoning only decreases after age 25 ?

Or is that unrelated ? I guess what I’m wondering is are we able to produce more and more complex reasoning as we age despite the fact that our prefrontal cortex only shrinks as time goes by ?

The prefrontal cortex is the last part of the brain that becomes white matter instead of just grey matter. It is the last part of the brain that gets upgraded by becoming myelinated.
