Connecting the Heart and Brain

The brain and the heart are in constant communication, sending signals that control and respond to each other, so it's no surprise that what's good for one is what's good for the other. Dr.  Robert Harrington, an esteemed cardiologist and the new Dean of Weill Cornell Medicine, joins us today to explore the fascinating conversations that go on between these two most important organs. From the electrical signals sent from the brain to the oxygenated blood flow the heart sends back, find out what keeps both organs going—and what happens when something disrupts that balance. Turns out you really can die of a broken heart, as a sudden intense emotional event can cause the brain to send a "stop" message to the heart; a disruption in the heart's blood flow can send a similar message to the brain.
