The only sure way to check brain dominance is to perform a medical test that involves
A) deep lesioning within each hemisphere.
B) assessing one cerebral hemisphere at a time.
C) spatial ablation.
D) karotyping and DNA analysis for lateralization.

Question

Quizplus · Accepted Answer

Assessing one cerebral hemisphere at a time is the best way to check brain dominance. This can be done through techniques such as the Wada test, where one hemisphere is put to sleep through medication and the other is tested for language and other cognitive functions. Deep lesioning and spatial ablation are invasive and harmful procedures, while karotyping and DNA analysis are not currently reliable methods for assessing brain dominance.
