ANECDOTE

One Armed Surfer Became A Pro Through Practice

  • Her recovery illustrates neuroplasticity: determination and repeated practice rewired her body and brain to compensate for balance and technique changes.

Learning Literally Reshapes Brain Structure

  • The adult brain remains plastic: repeated experience builds new neural pathways and can change brain volume in areas like the hippocampus.
  • London taxi drivers' hippocampi enlarged during training while bus drivers' did not, linking learning to structural change.

Myelination Turns Repetition Into Automatic Skill

  • Myelination makes frequently firing neurons faster and more automatic, like turning a dirt track into a highway.
  • The prefrontal cortex becomes highly myelinated around age 25, explaining prolonged development of executive function.
