Methodology to obtain and record evoked pupillary responses by auditive stimulation
Eduardo Moreno, J. Valdez Hernandez, Ernesto Suaste-Gómez · 2006
This paper shows an instrumental methodology to obtain pupilary responses provocated by auditive stimulation, modulating defensive reflex in darkness and lightness conditions. This records let us show the interconection between auditive stimulation and nervous activation, that is important in psychophysiology area [1], for the autonomy nervous system evaluation as well as vision and hearing senses. These responses are adquired by high intensity white noise hearing stimulation and the pupillary diameter register is based on video oculography infrared camera technique.
