How learning new skills can affect the brain's white matter over time, writes ckbergland
of the brain. Much like Braille allows people to read without sight, touch typing relies on a sense of touch, not sight.Source: Molendowska aMatuszewski et al., JNeurosci 2021This week, a white matter plasticity study was published in thethat shows how learning a new skill can change the functional connectivity and structure of WM over the course of eight months based on the brain's supply-demand needs.
White matter in somatosensory areas of the cerebral cortex strengthened steadily during the eight-week training course. But WM in the visual cortex didn't start to reorganize until about halfway through the Braille training. According to a July 12, these findings suggest that"white matter reorganizes itself across regions and different timeframes to meet the brain's needs."
"Taken together, these results demonstrate that white matter plasticity is a highly dynamic process modulated by the introduction of novel experiences," Molendowska et al. conclude."Our results confirm the supply-demand model of brain plasticity and provide evidence that WM reorganization depends upon distinct computational demands and functional roles of regions involved in the trained skill.
Then, she asked me a simple question,"Are you remembering to feel for the little Braille-like bumps on the"F" and"J" keys with the tips of your index fingers to establish your home-key position?"
