Abstract

This paper shows an instrumental methodology to obtain pupiliary responses provocated by auditive stimulation, modulating defensive reflex in darkness and lightness conditions. This records let us show the interconnection between auditive stimulation and nervous activation, that is important in psychophysiology area, for the autonomy nervous system evaluation as well as vision and hearing senses. These responses are acquired by high intensity white noise hearing stimulation and the pupillary diameter register is based on video oculography infrared camera technique
