The man behind the Troxler Effect: I.P.V. Troxler (1780-1866) -- The philosopher as neurophysiologist and vice versa

Gesundheitszentrum Fricktal, Rheinfelden, Switzerland

Concepts of visual perception and its modes and deficiencies have become a field of particular interest and intensive research effort throughout the international scientific community. Modern methods of neurophysiological research along with ever refined neuropsychological approaches produce an ever growing host of publications on subjects asuch as inattention blindness or peripheral fading. The first description of the latter phenomenon has been attributed to an obscure author who, in 1804, had published his observations in Ophthalmologische Bibliothek (edited by Karl Himly and Joh. Adam Schmidt), the first ophthalmological journal in history.

The aim of this contribution is to draw the attention of the modern research community to the simple but remarkably well structured experimental settings used by this author 200 years ago and to encourage in-depth reevaluation of his concepts from a modern point of view.
