<unk>  (from Greek , ēlektron, "amber" see the etymology of "electron"; , physis, "nature, origin"; and , -logia) is the branch of physiology that studies the electrical properties of biological cells and tissues. It involves measurements of voltage changes or electric current or manipulations on a wide variety of scales from single ion channel proteins to whole organs like the heart. In neuroscience, it includes measurements of the electrical activity of neurons, and, in particular, action potential activity. Recordings of large-scale electric signals from the nervous system, such as electroencephalography, may also be referred to as<unk> cal recordings. They are useful for electrodiagnosis and monitoring. "Current Clamp" is a common technique in<unk> . This is a whole-cell current clamp recording of a neuron firing due to it being depolarized by current injection
