Abstract

A method for generating an indicator or biomarker of colour perception in a mammalian subject, where the method may include submitting the mammalian subject to a multicoloured dynamic stimulus comprising displaying, on a display device. The method may include controlling a change over time of at least one of the two colours of the multicolour pattern when displaying the dynamic multicolour stimulus, to vary the displayed luminance of this colour (usually several times). The method may include acquiring, by using an image acquisition device, an oscillatory response of a pupil of the mammalian subject. The method may include generating, from the acquired response, a signal representative of the power of the pupil's oscillatory response as a function of the change over time of at least one of the two colours when displaying the dynamic multicoloured stimulus.
