At the beginning of the cardiac cycle the brain vasculature is draining the blood from the previous diastole. The new surge of blood into the brain arrives via the carotid arteries that originate from the aortic arch, distributing blood into all areas of the brain. The blood flow into the brain is not symmetric due to the asymmetry of the brain vasculature with the right common carotid branching from the aorta closer to the left ventricle of the heart than the left common carotid. This pulse of blood into the right hemisphere of the brain 10s of milliseconds before the flow into the left hemisphere begins to move the skull away from the right hemisphere before the pulse arriving into the left hemisphere slows that initial motion. This process puts the brain in oscillation with typically five complete oscillations within each heartbeat.

The BrainPulse system consists of a headset, data collector and computer. The headset contains a heart rate detecting sensor (PPG), a Sound Pressure Level (SPL) sensor for detecting ambient environment noise and six accelerometers to detect the acceleration of the skull at six selected locations. These components are assembled in a compact and portable headset. A touchscreen tablet provides the user interface to the BrainPulse device and stores the proprietary files from each recording session.
