Video transcript

Hello, everyone and welcome to today's video. So John is a left handed individual who recently suffered a stroke. The stroke affected the right hemisphere of his brain. One of the areas affected by the stroke is the precent virus in the right cerebral cortex. So how will this affect John's moderate abilities as answered choice. A we have that he may experience difficulty moving his right arm and leg voluntarily. B he may experience difficulty moving his left arm and leg voluntarily. C he may experience difficulty moving both his right and left arms and legs voluntarily. D he may not experience any changes in his moderate abilities due to his left handedness. Now, as it turns out in our brains, it is going to be the left hemisphere that is controlling the motor functions on the right side of the body. And just like that, it is going to be the right hemisphere that is controlling the motor functions in the left side of the body. We are told that John's injury or John's throat affected the right hemisphere of his brain. Therefore, he's going to have issues moving his the left side of his body, including his left arm and legs voluntarily. Now this is going to be making answer choice. B he may experience difficulty moving his left arm and leg voluntarily. The final answer to this question, I really hope this video helped you and I hope to see you on the next one.
