Love is often described as heartwarming, heart-wrenching, or even heartbreaking— and your brain is responsible for all these feelings. The journey from first spark to the last tear is guided by a symphony of neurochemicals and brain systems. Shannon Odell explores what happens in your brain when you fall in love, how it responds to a relationship, and how it reacts to a breakup.
