Darnell may have injured the hippocampus.

This part of the brain is responsible for mediating the storage of new information and its recovery, for that reason, when this area of the Limbic System is damaged, Darnell cannot store new information. Epilepsy is a disease in the nervous system that is due to an unusual electrical activity in the cerebral cortex. Seizures and loss of consciousness are among the main characteristics of the disorder. Generally, epilepsy is treated by means of anticonvulsant medications, however, sometimes the pathology is so severe that a surgical method is used.

I hope this information can help you.

Answer: Most likely, the surgery destroyed a portion of the hippocampus in Darnell's brain.

Explanation: The hippocampus is a part of the human brain. It is located in the medial temporal lobe of the brain. Moreover, the hippocampus has an important function since it is the part of the brain responsible for forming new episodic memories. Henry Gustav Molaison was a famous American patient who suffered from epilepsy and decided to undergo surgery to cure it; however, his condition got worse because his hippocampus was destroyed during the surgery. As a result, although Molaison continued to remember event from the past, he was unable to storage new memories from that moment onwards, which upheld the theory of an existing relationship between the hippocampus and the formation of new memories.
