Just caught the tail end of a CBC show on brain cells this morning. Some
guy from Vancouver's Brain Research Center said they'd recently learned
that new brain cells involved in learning continue to emerge every day
throughout old age, apparently at a rate of about 1000 per day if
focused solely on cognitive skills, and around 3000 per day when
actually doing physical exercise. Though we have about 10 billion brain
cells, each with 10's of 1000s of connections, not all areas are tied up
in learning. And specific areas can grow larger with focused skills such
as practicing piano scales, increasing the area associated with fingers
only.
Unfortunate that the athletically trained often suffer such body aches
in late life, and have to forgo those good habits.
