Yeah I should have gone even more generic with my term than pruning probably as it implies synaptic pruning when what I actually meant was like a plant: all of the reductions of connectivity that come with age including the reduction in neurons and increase in glial cells, etc.

Depending on how these networks are structured they may not be able to change much, but if they are structured in better ways then aging is less impactful.

I definitely could have been better in this thread.
