This course will explore the deep development of the central structures of the cardiovascular system, especially the heart-brain connection. Students will learn a new cerebrovascular circulation protocol. This protocol is based on research showing decreased blood flow to the brain following a mild traumatic brain injury. This is combined specifically with exploring the carotid sinus via Primary Respiration (PR). Palpation skills will include deeper exploration of the vertebral artery, the sagittal sinus and jugular vein.
