- Piroux's definition of hallucinations
- In 1861 the French physician A. Piroux (1803?-1884?) defined hallucinations as follows: "Exterior objects make an impression upon our sen-sorial surfaces, that impression is transmitted towards the brain that receives it, and from there it passes to the sphere of the understanding. Thus the not-I is brought in contact with the I, by means of three phenomena, namely: sensorial impression or sensation, transmission, perception of that sensation. Having stated this, we say that a hallucination is a perception without an adequate sensation."ReferencesPiroux, A. (1861). Fragments d'études sur les hallucinations. Thèse Université de Montpellier.
