...carotid artery on the left side of Kennedy's neck to clear the plaque that was building up inside it. The concern: that some of that arterial plaque might break off and form a clot in the Senator's brain, interrupting the flow of blood to his cerebrum. After the operation, he was probably also given aspirin or other medications to thin his blood and decrease the risk that he would form a clot...
EVEN GETTING OUT OF BED CAN BE TOUGH ON THE BODY. SEVERAL hours before you wake each morning, a tiny region at the base of your cerebrum called the hypothalamus sends a signal that ultimately alerts your adrenal glands, which sit on top of your kidneys, to start pumping out cortisol, which acts as a wake-up signal. Cortisol levels continue to rise after you become conscious in what is sometimes referred to as the "Oh, s___! It's another day" response. This may help explain why so many heart attacks and strokes occur between...
...McGill University in Montreal believes that the hippocampus, a finger-size structure located deep in the brain, is at least partially responsible. It turns out that the hippocampus, which helps you form new memories and retrieve old ones, is particularly sensitive to the amount of cortisol flooding your cerebrum.

As those neurons get excited, they activate nerve cells connected to the limbic system just under the cerebrum of the brain, the area associated with emotions such as fear, anxiety, elation and satisfaction. That area is tied in turn to the motor cortex, which controls the muscles...
