The F-H method allowed, for the first time, the examiner to watch these monoamines light up in the microscope and to precisely determine in which cells they were present, and thereby understanding their functions.
[3] The method was developed by Bengt Falck and Nils-Åke Hillarp in the 1960s at the Department of Histology, University of Lund.
The initial publication, written already in 1961,[4] described a wide-ranging examination of nerves supplying a large number of organs in the body.
This work validated the concept of Ulf von Euler, the Nobel prize winner, that noradrenaline is the signal substance in peripheral autonomic nerves.
[citation needed] In 2012, the Faculty of Medicine at the University of Lund arranged a symposium “From Nerve to Pills” celebrating the 50th anniversary of the initial publication of the F-H method.
