The branch of physiology and neuroscience that is concerned with the study of the functioning of the nervous system is defined as Neurophysiology. The primary apparatuses of basic neurophysiological research comprises electrophysiological soundtracks, such as voltage clamp,  extracellular single-unit recording, patch clamp, and recording of local field potentials, as well as some of the methods of calcium imagination, optogenetics and molecular biology.  Neurophysiology is connected to neuroanatomy, neurochemistry, electrophysiology, biophysics, and mathematical neuroscience. It also has therapeutic applications in clinical neurophysiology and clinical neuroscience.
