A) The size of the posterior corpus callosum increased in early-trained musicians.
B) The size of the anterior corpus callosum increased in late-trained musicians.
C) The size of the posterior corpus callosum decreased in early-trained musicians.
D) The size of the anterior and posterior corpus callosum was equivalent in both groups of musicians.

Question

Studies on musicians, particularly those who began their musical training early, often show increased size or connectivity in certain brain regions due to the high demands of their activity on brain plasticity. The posterior corpus callosum, which connects the two hemispheres of the brain, is one area where changes have been observed, reflecting the intense interhemispheric communication required for musical performance.
