Question

An individual was admitted to the hospital after experiencing a mild tingling on the right side ofthe face and a sudden inability to speak. Using magnetic resonance imaging (MRI), an abnormality in the brain tissue of the ______ hemisphere

Answer 1

Answer:

left

Explanation:

Our brain is divided into two hemispheres, left and right. Each hemisphere tends to specialize in controlling different body functions, but a curious thing about our brain is decussated - that is, the left and right hemisphere are crossed: the left hemisphere controls the right side of the body, and the right hemisphere controls the left side. Generally speaking, this means that any damage caused to a hemisphere will manifest on the opposite side of the body. In our example, since the individual is experiencing a tingling on the right side of the face, the MRI will show an abnormality in the brain tissue of the left hemisphere.
