This area of ​​your brain does not mature until you turn 36


Our brain wires in the early years of our lives and remains static, although new findings in neuroplasticity may suggest that this is not exactly the case. What has never been seen is that there is an area of our brain that is evolving continuously until we turn 36 approximately.

This area of the immature brain until age 36 is the primary visual cortex (VI), the brain area that processes and interprets visual information.

Primary visual cortex

The primary visual cortex is responsible for processing the information that comes from the retinas, then send it to another 20 specialised areas, a work of about 280 million neurones. And so far, based on animal studies, it was believed that this region reached maturity at the age of 5 or 6 years.

The study that has presented this finding has been published in the Journal of Neuroscience by Kathryn Murphy and colleagues at McMaster University in Canada. According to the author herself:

Our idea that the sensory areas of the brain end up evolving in childhood is completely wrong.

The finding of the plasticity of the primary visual cortex may open therapeutic pathways in some pathologies of vision, such as the vagus eye, dismissing the idea that only children can respond to corrective therapies.
