Imagine a person who suffers a stroke. The individual can understand language perfectly and decide precisely what she wants to say or write. However, the individual cannot communicate the thoughts. Of the choices below, you would suspect damage to the Select one: a. The precentral gyrus b. Primary auditory cortex c. The postcentral gyrus d. Primary visual cortex e. A multimodal association area

a. the precentral gyrus

Explanation:

Of the choices below, you would suspect damage to the precentral gyrus. This is a part of the brain known as the primary motor cortex whose main responsibility is executing voluntary movements around the body. This includes moving muscles such as on your face, lips, throat, arms, etc. All of the necessary muscles to be able to communicate your thoughts properly are controlled through the motor cortex. Therefore, if the individual in this scenario, cannot communicate their thoughts properly it is most likely because the stroke caused damage to the precentral gyrus.
