研究概览
简要总结
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.

结局指标
主要结局
Comparison of cerebral activations between the different supports mediating the olfactory imagination during the execution of the fMRI tasks.
时间窗: Baseline (J0)
The cerebral activations between the different supports mediating the olfactory imagination will be compared in terms of localization and intensity of the variations of the BOLD signal during the execution of the fMRI tasks.
次要结局
- Description of the evolution of the cardiac activity during olfactory imagination tasks in fMRI.(Baseline (J0))
- Determination of the visual support allowing the strongest olfactory imagination during the fMRI by subjective evaluations using two 4-level Likert scales.(Baseline (J0))
- Determination of the visual support allowing the strongest olfactory imagination during the fMRI test by the cerebral activations in areas recognized for their implications in the olfactory imagination.(Baseline (J0))
- Description of the evolution of the respiratory activity during olfactory imagination tasks in fMRI.(Baseline (J0))
- Evaluation of the state of discomfort in virtual reality by measuring the cardiac activity.(Baseline (J0) and 6 months maximum after J0 (V1))
- Evaluation of the state of discomfort in virtual reality by the "Simulator Sickness Questionnaire" (SSQ) before and after immersion.(Baseline (J0) and 6 months maximum after J0 (V1))
