Question

Quizplus · Accepted Answer

Geschwind hypothesized that right-hand apraxia was associated with damage to the area that connects language areas and the motor cortex in the left hemisphere, which is known as the arcuate fasciculus. This area is responsible for linking language and movement, making it critical for tasks that require complex motor sequencing and coordination, such as tool use and gesture production. Damage to this area can result in apraxia, a disorder in which individuals have difficulty performing purposeful movements or using tools, even though they have intact motor abilities.
