Thalia Harmony & E. Roy John 
Functional Neuroscience [PDF ebook] 
3 Volume Set

The late E. Roy John is considered the pioneer in the field of neurometrics – the science of measuring the underlying organization of the brain’s electrical activity. Volume 1, co-authored by Robert W. Thatcher, and Volume 2 both originally published in 1977, were among the first books this field. Volume 3, written by colleague Thalía Harmony, followed in 1984. The field expanded significantly in the 1990s and thousands of articles have subsequently been published. Available together for the first time these 3 volumes were important foundational works for the fields of quantitative electrophysiology and neurometrics.
