Your brain rewires itself after age 40

I turn 42 later this year, and this would explain a lot. Not in terms of me being unable to be super-efficient and productive, but just in terms of seeing connections everywhere.

In a systematic review recently published in the journal Psychophysiology, researchers from Monash University in Australia swept through the scientific literature, seeking to summarize how the connectivity of the human brain changes over our lifetimes. The gathered evidence suggests that in the fifth decade of life (that is, after a person turns 40), the brain starts to undergo a radical “rewiring” that results in diverse networks becoming more integrated and connected over the ensuing decades, with accompanying effects on cognition.

Early on, in our teenage and young adult years, the brain seems to have numerous, partitioned networks with high levels of inner connectivity, reflecting the ability for specialized processing to occur. That makes sense, as this is the time when we are learning how to play sports, speak languages, and develop talents. Around our mid-40s, however, that starts to change. Instead, the brain begins becoming less connected within those separate networks and more connected globally across networks. By the time we reach our 80s, the brain tends to be less regionally specialized and instead broadly connected and integrated.

“During the early years of life, there is a rapid organization of functional brain networks. A further refinement of the functional networks then takes place until around the third and fourth decade of life. A multi-faceted interplay of potentially harmful and compensatory changes can follow in aging,” the reviewers concluded.

🎺 What Time Feels Like When You’re Improvising — “A great example of flow state is found in many improvised art forms, from music to acting to comedy to poetry, also known as “spontaneous creativity.” Improvisation is a highly complex form of creative behavior that justly inspires our awe and admiration. The ability to improvise requires cognitive flexibility, divergent thinking and discipline-specific skills, and it improves with training.”

💼 SEC proposes rules for giving gig workers equity — “The five-year pilot program would allow gig companies to issue equity as long as it’s no more than 15% of a worker’s compensation during a 12-month period, and no more than $75,000 in value during a 36-month period (based on the share price when it’s issued).”

🧠 Your Brain Is Not for Thinking — “Your brain’s most important job isn’t thinking; it’s running the systems of your body to keep you alive and well. According to recent findings in neuroscience, even when your brain does produce conscious thoughts and feelings, they are more in service to the needs of managing your body than you realize.”

Social Unrest Is the Inevitable Legacy of the Covid Pandemic — “Like turpentine on flames, Covid-19 has rekindled older divisions, resentments and inequities across the world. In the U.S., Black Americans suffer disproportionately from police brutality, but also from the coronavirus — now these traumas merge. And everywhere, the poor fare worse than the rich.”

👣 A new love for medieval-style travel — “We might today think of pilgrimage as a specifically religious form of travel. But even in the past, the sightseeing was as important as the spirituality. Dr Marion Turner, a scholar at Oxford University who studies Geoffrey Chaucer, points out that “it was a time away from ordinary society, and allowed for a time of play.”
