"神经科专门医师" can be translated into English as "neurologist" or "specialist in neurology".
"Neurologist" is the more commonly used and concise term, referring to a medical doctor who specializes in diagnosing and treating disorders of the nervous system.
"Specialist in neurology" conveys the same meaning but in a more descriptive and literal way.
In most contexts, "neurologist" would be the preferred choice.
