PSYB65H3 Lecture Notes - Schwann Cell, Glioma, Meningioma
Document Summary
Don"t need to know dates or names (unless the name is very important) Monday lecture on oct 31 is not on the midterm. Blood carries oxygen and sucrose (can only survive without o2 for 3 mins) Brain has very high metabolic rate: easy to get damaged from lack of blood flow. Glucose deprived -> not so much neurological, but more physical. There"s no o2 backup system, but glucose has storages. Types of problems: blockages, cerebral vascular accident (cva) - blockage of blood flow, most commonly referred to as a stroke , but cva is more specific, severe interruption of blood supply of the brain c. Ischemia => not enough blood glucose / oxygen - disruption of blood oxygen in brain d. Ischemic -> lack of blood flow/ oxygen: transient -> temporary, not permanent b, common -> a lot of people have experienced, associated with vascular constriction and get lack of blood to brain.
