Which of the following sometimes happens in people with damage to the corpus callosum?

pointing to the correct answer with the left hand while saying, “I don’t know.”

smiling after a gentle stroke on the right arm, without consciously feeling it

seeing an object but not being able to identify which direction it is moving

speaking the correct words, but saying them backwards

Solution

Ans A

The people with damaged corpus callosum face problems with speech and object recognition.

The information from their left hand is relayed to the Right hemisphere of the brain which has a weak language centre.

Without intact corpus callosum one cannot access verbal information in the left hemisphere as long as it is indicated with left hand. Hence the patient faces difficulty using the left hand to execute his verbal commands and ends up messing it often
