Labib has been having severe epileptic seizures since a very young age. His seizures have become less frequent since he underwent an operation. However, he has problems expressing what he feels. When he feels happy, his facial expressions often show anger. Labib has most likely undergone a(n) operation.

A split-brain operation.

Explanation:

Basically, a split-brain operation may be performed on a patient with extreme/uncontrollable forms of epilepsy, and can affect many functions after the operation.

In this case, Labib would have undergone the operation due to his severe epileptic seizures, and would have trouble expressing cognitive and motor control, both of which are crucial to making the right face gestures to convey the correct emotions, hence the case in the question.

Hope this helped!
