Summary

This study looked at whether the time between heartbeats matches the time between brain pressure pulses in healthy people. 103 adults wore a headband, EKG, and finger clip for 15 minutes. The goal was to see if a simple brain monitor could replace complex heart tests, but no treatment was given.
