Research on brain plasticity shows that when healthy brain regions take over the functions of damaged areas,
A) children's IQ scores increase by 10 to 15 points, on average.
B) the brain processes information more quickly and accurately than it would if it were intact.
C) a "crowding effect" occurs in which multiple tasks must be done by a smaller than usual volume of ?brain tissue.
D) neurons in the healthy regions tend to die, leaving those areas vulnerable to future damage.

When healthy brain regions take over the functions of damaged areas, a "crowding effect" occurs in which multiple tasks must be done by a smaller than usual volume of brain tissue. This means that the brain has to work harder to accomplish tasks because it has less tissue available to do the same amount of work. However, this does not necessarily lead to an increase in IQ scores or faster, more accurate processing of information. Additionally, neurons in the healthy regions do not tend to die as a result of taking over functions from damaged areas.
