Apparently some of the white matter cells around the ventricles have died due to small blood vessel inability to supply them with enough oxygen. Basically the brain's gray matter are our pools of information. The brain's white matter relays signals. These signals access and connect gray matter information to help us carry out physical and mental acts, from walking etc., to remembering stuff.
Ischemia is the medical term for decreased blood flow. Ischemia limits the supply of oxygen to tissues.

Because if you play with a white square on the left side, the locations of the white / black bishops on each side will be reversed. Also the King and Queen will be reversed. This will can confuse experienced players who are used to them being where they are. Additionally, if inexperienced players switch back and forth on which orientation they play in, they won't develop the white / black intuition that you get from playing on a consistent board orientation.
what is the meaning of negative for provocable ischemia
It depends where the obstruction and ischemia are suspected of being located.
what is reversible vs irreversible ischemia in the brain
ischemia is a result of hypoxia. hypoxia means low oxygen in the heart.
Symptomatic ischemia is characterized by chest pain called angina pectoris.
Ischemia is interruption of blood flow.embolus
The best test for ischemia of any organ is angiography.
