Neurophysiology is mostly studied since 4000 B.C. It is a branch of physiology which also includes neuroscience. Both physiology of neuron and neuroscience combine with each other to know the function of Neurophysiology. This is concerned with investigation and function of peripheral and central nervous system.

Clinical Neurophysiology

Mostly encompasses both pathophysiology and clinical methods used to diagnose the disease in central and peripheral nervous system. It is an area of study through which bioelectrical activity is recorded, it may be spontaneous or stimulated. Clinical tests are conducted based on electrical functions of brain, spinal cord and nerves in limb and muscles. Electromyography, electroencephalography, evoked potential and polysomnography are used in clinical neurophysiological assessment.


It is mainly investigate neurological origin of cardiac disorders. This is studied with heart interactions with peripheral and central nervous system. Neurorcadiology is an aspect of neuroanatomical, physiological, and neurological aspects of cardiology.

Neuropsychology in the Era of Precision Medicine

Precision medicine is defines as the ways in which treatments can be optimized to align with the specific characteristics of an individual and to reflect individual-specific variability in physiology, environment and lifestyle.
