This question is from a case study which i went through to find the answer of the question. In the case study Albert suffered from a stroke in which his left side of the brain was affected. However, the symptoms were present in the right side of the body.
This actually happens when a person experiences stroke his symptoms are present only in single side of the body because of the rupture of the blood vessels in specific side.
As we know that when descending nerve tracts intersect each other, the right side of the body is controlled by left side of the brain and left side of the body is controlled by the right side of the brain.
Therefore, when the symptoms of Albert were localized in only right side, it was concluded that Albert had suffered the damage in right side of the brain.
