Recent Study Claims Your Brain Has 5 Different Eras In A Lifetime, Know Which You Are In?

If you are in your late 20s and tired of dealing with adulting, let us tell you that your adult era has not even begun for your brain. Yes, a recent study by scientists at Cambridge University has revealed that the human brain undergoes development across five ‘major epochs’ or 'eras' in a single lifetime, with the adult mode not starting until the early 30s.

This recent study, published in Nature Communications, claims that the brain doesn’t grow and develop abruptly, but neural wiring continuously evolves from infancy to old age, and ultimately declines. Let us tell you more about the study and the different brain eras at different ages:

What Is The New Study All About?

The study was conducted on almost 4,000 people aged from zero to 90, mapping neural connections and how these connections rewire and evolve throughout life. The research revealed that the brain goes through five different epochs, split up by four major turning points between birth and death, when our brains reconfigure around the ages of 9, 32, 66, and 83.

Senior author Prof Duncan Astle, Professor of Neuroinformatics at Cambridge, reports in a Cambridge University statement, “Looking back, many of us feel our lives have been characterised by different phases. It turns out that brains also go through these eras.”

“Many neurodevelopmental, mental health, and neurological conditions are linked to the way the brain is wired. Indeed, differences in brain wiring predict difficulties with attention, language, memory, and a whole host of different behaviours,” he further added.

At What Age Are You In Which Era?

We all know how crucial it is to understand how and when the brain rewires, transferring from one mode to another, eventually changing its approach towards life, and impacting a human being’s day-to-day experience.

According to the study, the childhood brain topology goes from birth until the age of nine or somewhere around. Nine is the age when different brain networks begin communicating, transitioning into the Adolescent phase, which lasts right up to the age of 32.

In the early thirties, the brain’s neural wiring shifts into the Adult mode, which is the longest era and lasts for almost three decades.

A third turning point hits around the age of 66, marking the early ageing phase of brain architecture. At the age of 83 and around is when the late ageing phase of the brain takes shape.

Dr Alexa Mousley, a Gates Cambridge Scholar who led the research mentioned in the published study, "This is the first study focusing on identifying major phases of brain wiring across a human lifespan."

“These eras provide important context for what our brains might be best at, or more vulnerable to, at different stages of our lives. It could help us understand why some brains develop differently at key points in life, whether it be learning difficulties in childhood, or dementia in our later years,” she added.

The Final Word

Rewiring of neural connections in the brain affects not only the day-to-day experiences and projections of a human being but also defines their overall well-being. The scientists have claimed that understanding these five different eras of the brain will help diagnose and treat several mental health disorders and other chronic illnesses, which worsen as individuals grow older.
