Neurophysiology is a broad field of study because many different levels are involved in the overall functioning of the nervous system and its components. For example, the transmission of a nervous impulse across the synapses, or the cleft that connects nerve cells, involves chemical reactions at the cellular level of organization. Understanding how messages are relayed from the brain to the hand is best explained at the system level. This involves studying the relationship and pathways between the brain and the organs of the body and the nerves that connect them, both sensory, meaning nerves that receive input from sensors, and motor, meaning the nerves that activate muscle. Thus, neurophysiology studies nervous function ranging from individual nerve cells to the complex behaviors of the central nervous system. Additionally, the nervous system not only functions at the cell and system levels of organization, but ... at a mechanistic level, that involves the study of the control or regulatory processes that occur.

Neurophysiology is a diagnostic specialty concerned with recording and interpreting electrical signals from the nervous system. It is important in the evaluation of peripheral nerve and brain function, often a key element in the diagnosis and assessment of diseases of the nervous system, such as epilepsy, muscle and peripheral nerve disease, sleep disorders, or monitoring of nerve function.

Neurophysiology deals with the way the mind and body interact and how the body systems work in an intergrated way according to the needs of the individual. Neurophysiology is the science which explains how ideas, beliefs, and emotional issues have an impact at the level of the cell - and how stress and psychological impairment can result in disease, chrinic illness, under-performance, learning difficulties, and loss of a sense of well-being.

Neurophysiology workstations can easily be expanded to add complete integrated stimulus production capabilities. System 3 devices can be used to generate acoustic, vibrotactile, or vestibular stimulus waveforms; control visual stimulus generators or olfactometers; or generate electrical microstimulation waveforms.
