According to the passage, the processing of received data in the brain is ---- .
The brain, like all of the body's organs, responds
to both inherited and environmental factors that
can enhance or diminish its amazing capacities.
One of the challenges researchers face when
studying the human brain is to distinguish among
normal age-related physiological changes,
changes caused by diseases, and changes that
result from cumulative, extrinsic factors such as
diet. The brain normally changes in some
characteristic ways as it ages. For one thing, its
blood supply decreases. For another, the number
of neurons, the brain cells that specialize in
transmitting information, diminishes as people
age. When the number of nerve cells in one part
of the cerebral cortex diminishes, hearing and
speech are affected. Losses of neurons in other
parts of the cortex can impair memory and
cognitive function. When the number of neurons in
the hindbrain diminishes, balance and posture are
affected. Losses of neurons in other parts of the
brain affect still other functions.
