Alternately: Internal Pattern Recognition: IPR? đ
If there’s one thing that Stoicism has taught me, it is that the good fight is not with the world, but yourself. Many of the books I read and observations I try to make on family are to get a better understanding of the ‘why’ behind my thinking. Among the many things that “Behave” gave me insights on was this, and an explanation for how siblings can be very different in terms of mindset and behaviour, despite inheriting not just ‘nature’ but sharing ‘nurture’ too.
‘Another dogma was that brains are pretty much wired up early in childhood – after all, by age two, brains are already about 85% of adult volume, but the development trajectory is much slower than that. …the final brain region to fully mature (in terms of synapse number, myelination, and metabolism) is the frontal cortex, not going fully online until the mid twenties.‘
“…the brain is heavily influenced by genes. But from birth through young adulthood, the part of the human brain that most defines us (frontal cortex) is less a product of the genes with which you started life than of what life has thrown at you. Because it is the last to mature, by definition the frontal cortex is the brain region least constrained by genes and most sculpted by experience. This must be so, to be the supremely complex social species that we are. Ironically, it seems that the genetic program of human brain development has evolved to, as much as possible, free the frontal cortex from genes.â
