Reorganization of neural circuits after damage to the mammalian brain is thought to occur largely through the
A) accurate regeneration of the damaged neurons.
B) strengthening of existing connections by release from inhibition.
C) establishment of new connections by collateral sprouting.
D) all of the above
E) both B and C

Question

Quizplus · Accepted Answer

Accurate regeneration of damaged neurons is unlikely to occur in the mammalian brain, meaning A is not the best choice. Instead, reorganization of neural circuits after damage is thought to occur through the strengthening of existing connections by release from inhibition (B) and the establishment of new connections by collateral sprouting (C). Therefore, the best choice is E, which includes both B and C.
