Morris felt like his years of being a doctor were wasted; after all, he was a top neurosurgeon, yet he couldn't answer Professor Yang's questions now.
From Professor Yang's eyes, it was evident that he was disdainful of further communication with a doctor who couldn't answer his questions. But where could one learn such knowledge?
Morris wasn't entirely unfamiliar with this area of knowledge; as a neurosurgeon, he certainly didn't have as deep an understanding as scholars studying foundational neuroscience, just like internal medicine doctors know about diagnoses and medication, but if it's about pharmacological knowledge, they definitely don't go as deep as professors specializing in pharmacology. Morris only possesses some simple pharmacological knowledge useful in a clinical setting.
