In neurophysiological studies, the motor system is modeled as a distributed, often hierarchical system with the spinal cord controlling the "most automatic" of movements such as stretch reflexes, and the cortex controlling the "most voluntary" actions such as reaching for an object, with the brainstem performing a function somewhere in between the two.
Arvanitaki contributed to the field of neurophysiology with research that explored the giant nerve fibres in genera of gastropods, the sea hare Aplysia and the land snail Helix.
After completing his medical exams at Ludwig-Maximilians University in Munich, he became a medical assistant in 1968 at Munich University, while also working as a scientific assistant (Wissenschaftlicher Assistant) at Munich's Max-Planck-Institut für Psychiatrie, in the Neurophysiology Department under Otto Detlev Creutzfeldt.

Dr. Policharla completed his residency in Neurology at Wayne State University in Detroit, Michigan and is Board Certified in Sleep Medicine, Clinical Neurophysiology, and Epilepsy.
After completing her graduate work at the Neurological Institute in Queen's Square, London, she moved to the United States in 1960 to teach Neuroanatomy and neurophysiology at the Columbia Presbyterian Hospital Neurological Institute.
From 1969 to 1977, he was Director of Neurophysiology at the Georgia Mental Health Institute in Atlanta.
He trained as post-doctoral fellow in Neurophysiology at Stanford University Medical School (California) under the mentorship of Professor Karl H. Pribram.
Based on the neurophysiology of a healthy human brain (unlike other therapies based on introspection, observation, or the philosophical influences of Hellenistic Stoicism on Rational Emotive Behavior Therapy).
Between 1970 and 1973, his additional areas of research interest included cerebellar physiology, and from 1972 to 1981, receptor characteristics and central connections in fine muscle afferents, and in 2012, the neurophysiology of nociception and pain, especially in relation to joint pain.
