electrophysiology
Cellular voltage studies
Electrophysiology is the study of electrical activity in living cells and tissues, particularly in the heart and nervous system.
Medical electrophysiology diagnoses and treats heart rhythm disorders: The cardiologist recommended an electrophysiology study to identify the source of her arrhythmias.
In research, it examines how neurons transmit signals through electrical impulses.
