Neuroscientists and those in middle age or beyond know
that brains alter and slow as we grow older. Processing
speed, which is a measure of how rapidly our brains can
absorb, assess and respond to new information, seems to
be particularly hard hit. Most people who are older than
about 40 perform worse on tests of processing speed than
those who are younger, with the effects accelerating as
the decades pass.
(A) But in older people, brain scans show, the white
matter can be skimpier and less efficient. Messages
stutter and slow.
(B) Scientists suspect that this decline is due in large
part to a concomitant fraying of our brain's white
matter, which is its wiring.
(C) In young brains, these messages whip from neuron
to neuron with boggling speed.
(D) White matter consists of specialized cells and their
offshoots that pass messages between neurons and
from one part of the brain to another.
