Questions and Answers

What is the primary reason why rapid reorganization of the brain does not involve changes of more than 2 mm of cortical surface?

Because it is a quick process and neural growth is slow
Due to limits of neural growth (correct)
To prevent interference with other brain functions
Due to the maximum capacity of cortical reorganization

What is the main difference between recovery of function and compensatory changes after CNS damage?

Recovery of function is a result of neural growth, while compensatory changes are a result of neural degeneration
Recovery of function is a return of lost functions, while compensatory changes are new cognitive and behavioral strategies (correct)
Recovery of function is a long-term process, while compensatory changes are short-term
Recovery of function is a partial process, while compensatory changes are complete

What is the role of cognitive reserve in improvements observed after brain damage?

It accomplishes tasks in alternative ways (correct)
It results in true recovery of brain function
It slows down the decline of brain function
It prevents further damage to the brain
