What happens when we pass out? Researchers ID new brain and heart connections

Scientists have discovered a genetic pathway between the heart and brain tied to fainting, suggesting that the heart sends signals back to the brain that can change its function. The study found that vagal sensory neurons play a key role in fainting, with their activation leading to rapid pupil dilation, suppressed heart-rate and breat...
