The human brain has gotten bigger, but are we smarter? We have the answer

A recent study confirms that the size of our brains has increased since the 1930s.

Artificial intelligence recreates the human brain

Modern technology can constantly stimulate our brain, although we recommend doing this through scientific TikTok accounts, for example. Given that we are still a long way from integrating brain-machine connections as cinema has shown us, perhaps it is time to clarify whether larger brain size is a synonym greater intelligence.

Larger brain size and greater ability to avoid loss of brain function

A recent study published in the scientific journal JAMA Neurology reveals a study that took 75 years must be completed and which reveals the main Aspects which were discovered about brain size in different generations of people.

Researchers from the University of California, Davis were able to test how the brains of their participants worked study much wider among people born later when comparing data subjects born per decade 1930 and those born in the decade 1970.

Charles DeCarli is the study’s lead author and director of the Alzheimer’s Disease Research Center at the University of California, Davis. According to an article published on the website of the University of California at Davis, Prof. declares:

The decade in which a person is born appears to influence brain size and potentially long-term health. Genetics plays an important role in determining brain size, but our results point to external influences such as educational, cultural, social and health factors that may also play a role.

This research began in 1948in Framingham, Massachusetts, and united 5209 volunteers and volunteers from 30 to 62 years old. An investigation during which Magnetic resonance imaginghas survived to this day and includes the second and third generations.

Between 1999 and 2019, MRI scans were conducted on people with an average age of 57 years, with a total of 3,226 participants. Data from people born in different decades were compared and it was found that brain volume of those born in the decade 1970 was 6.6% olderBeing cerebral cortex area A 15% more than those who were born in 1930s.

No data on whether we’re getting smarterthis is a very difficult parameter to measure, but we know that dementia has been declining over decades, and this brain growth may be one of the most determining factors. Charles DeCarli states What:

Larger brain structures like those observed in our study may reflect improved brain development and health. Larger brain structure represents greater brain reserve and may mitigate the later life effects associated with brain diseases such as Alzheimer’s disease or dementia.
