The left scan is taken from a. The fascia lata or the deep fascia of the thigh is an especially strong fascial sheath which envelops the thigh like a sleeve. The higher functions of the brain cease activity once the blood supply and therefore oxygen transport is interrupted.
The scans show where the cocaine interferes with the brains use of glucose - or its metabolic activity. The mammalian brain depends on glucose as its main source of energy. A stroke is a medical condition in which poor blood flow to the brain causes cell death.
