A previous study has suggested that our brains are technically in their adolescent phase until about 32, with the adulthood section running ’til about 66.
But a new paper published in Science found that the brain seems to undergo sweeping changes in how its genome is regulated, starting in midlife.
Study author Nathan Zemke, Director of Single-cell Genomics at the Centre for Epigenomics at UC San Diego, described the finding as “a major step forward in understanding how aging reshapes the human genome in brain cells”.
What happens to the brain between 50 and 75?
In this research, scientists used single-cell analyses involving samples from participants’ hippocampi (the parts of the brain linked to learning and memory) to look at their gene regulation and gen...
