No results posted yet for this study

Summary

The aim of this study is to, using fMRI, compare brain activations during olfactory imagery induced by different visual supports (words, pictures, colors and colored arrangements) in healthy subjects.

This will allow us to choose the best olfactory imagery facilitator and to assess its effect on cybersickness.

  • Healthy

Interventions

DEVICE

Functional MRI

The volunteer will have to imagine the smells evoked by different visual aids. This task will be carried out during 2 acquisition runs of about 10 minutes each. The volunteer should note (on a scale from 1 to 4) the pleasantness of the smell evoked.

OTHER

Virtual Reality: control

The volunteer will be immersed in a virtual maritime environment with nauseating characteristics. In the center of the maritime scene, it will be visible the black outlines of a frame. Every minute, the volunteer will be asked to verbalize the level of his general condition via the Fast Motion Sickness Scale (1 to 20).

OTHER

Virtual Reality: experimental

The volunteer will be immersed in a virtual maritime environment with nauseating characteristics. The visual support inserted in the center of the virtual scene will be the one defined as being the most facilitator of the olfactory imagination during the fMRI examination. The volunteer will be asked to concentrate on the smell evoked by this support. Every minute, the volunteer will be asked to verbalize the level of his general condition via the Fast Motion Sickness Scale (1 to 20).
