Explanation / Answer
Ans. (A). Seeing the right visual field.
As a result of this stroke, John's grandfather will face challenges in seeing the right visual field. He is now suffering from conjugate eye deviation (CED) or ipsilesional gaze shift. It is a symptom indicating brain damage wherein the pupils of the eye tend to move toward the side of the body where the lesion is located.
Had there been a damage to the frontal lobes of the grandpa then he would have faced trouble in planning behavior and making decisions and also speaking and understanding language. Because injury to the frontal lobes can cause a wide variety of symptoms. The frontal lobes are involved in motor function, problem solving, spontaneity, memory, language, initiation, judgment, impulse control, social and sexual behavior. It is observed that there are important asymmetrical differences in the frontal lobes. The left frontal lobe is involved in controlling language related movement, whereas the right frontal lobe plays a role in non-verbal abilities.The frontal lobes are considered our emotional control center and home to our personality. With regards to interpreting the facial expressions of other people, one particular brain region in the temporal lobe is responsible. It is the superior temporal sulcus. This region of the temporal lobe helps in interpreting specific facial movements such as surprise, disgust or happiness.
