The Drescher Iris Reflex — Iris Color Modulation as a Psychophysiological Protection Reflex

Abstract

Der Drescher-Iris-Reflex beschreibt ein neu identifiziertes psychophysiologisches Phänomen, bei dem die Iris eine schnelle, sichtbare Farbmodulation zeigt, die weder von der Beleuchtung noch von der Pupillengröße abhängt. Der Reflex korreliert mit emotionaler, kognitiver und autonomer Aktivierung und könnte einen Schutzmechanismus darstellen, an dem die Amygdala-Insula-Thalamus-Achse beteiligt ist. Säuglinge zeigen den Reflex häufiger, was auf eine frühe Form der Selbstregulation hindeutet. Durch eine Selbstinduktionsübung lässt er sich willentlich hervorrufen.

The Drescher Iris Reflex describes a newly identified psychophysiological phenomenon in which the iris exhibits rapid, visible color modulation unrelated to lighting or pupil size. The reflex correlates with emotional, cognitive and autonomic activation and may represent a protection mechanism involving the amygdala–insula–thalamus axis. Infants display the reflex more frequently, suggesting an early form of self-regulation. A self-induction exercise allows voluntary reproduction.
