A word used by doctors and nurses to imply that a patient’s problems are all in their mind. The tentorium is a membrane just under the brain, so “supratentorial” refers to what is above that, namely the brain. This term can be used in front of the patient or patient’s family because it sounds like technical jargon.
Sehr, sehr fein! 😀
