Myelination of the brain continues through childhood into adolescence and early adulthood--the question is, Why? Two new articles provide intriguing evidence that myelination may be an underappreciated mechanism of activity-dependent nervous system plasticity: one study reported increased myelination associated with extensive piano playing, another indicated that rats have increased myelination of the corpus callosum when raised in environments providing increased social interaction and cognitive stimulation. These articles make it clear that activity-dependent effects on myelination cannot be considered strictly a developmental event. They raise the question of whether myelination is an overlooked mechanism of activity-dependent plasticity, extending in humans until at least age 30. It has been argued that regulating the speed of conduction across long fiber tracts would have a major influence on synaptic response, by coordinating the timing of afferent input to maximize temporal summation. The increase in synaptic amplitude could be as large as neurotransmitter-based mechanisms of plasticity, such as LTP. These new findings raise a larger question: How did the oligodendrocytes know they were practicing the piano or that their environment was socially complex?

"What can you really think about in that amount of time?"
Nothing. You simply plan ahead and allow the "Law" to take care the business "in that amount of time.

"They send precise signals along wires that give the signal to myelinate that wire."
Do you?
What's your precise signal?
Do you send the same signal precise enough when facing a shot over a water to a well guarded green?
What matters is that signal, or the intent!!!
__________________ Yani Tseng, Go! Go! Go! Yani Tseng Did It Again! YOU load and sustain the "LAG", during which the "LAW" releases it, ideally beyond impact.
"Sustain (Yang/陽) the lag (Yin/陰)" is "the unification of Ying and Yang" (陰陽合一).
The "LAW" creates the "effect", which is the "motion" or "feel", with the "cause", which is the "intent" or "command".
"Lag" is the secret of golf, passion is the secret of life.
Think as a golfer, execute like a robot.
Rotate, twist, spin, turn. Bend the shaft.
Nothing. You simply plan ahead and allow the "Law" to take care the business "in that amount of time.

Hi BTS,
Remember the bits in bold are by a Prof in Neurology and not a golfer... he is explaining it to lay people in a newspaper article...
All he is saying is that repetitive use of a neuronal pathway increases the myelin around those neurones hence making that pathway more rapid conductor...
