Brief summary
Identify, characterize and then validate electrophysiological markers linking electrophysiological cerebral activity and performance in cognitive and physical fatigability in humans. To do this, noninvasive explorations of electroencephalography (EEG) and magnetoencephalography (MEG) will be carried out under two conditions of different experiments, the first one that induces a cognitive fatigability and the second one that induces physical fatigability.
Interventions
OTHERElectroencephalography (EEG) multi-sensor
Electrophysiological measurements of cerebral activity will be performed by multi-sensor electroencephalography (EEG), which is a non-invasive method.
Electrophysiological measurements of brain activity will be performed by magnetoencephalography (MEG) which is a non-invasive method.
OTHERBehavioral Measures
The evaluation of cognitive performance will be carried out by means of behavioral measures, push-button type, handling of a mouse or a joystick.
OTHERReaction time measurement
The assessment of cognitive performance will be carried out using standard behavioral measures, such as reaction time measurement.
OTHERAssessment of physical performance
The assessment of physical performance will be based both on bioenergetic measurements and on quantitative data collected in continuous and relative to the effort (eg instantaneous pedaling speed).
In order to extract artifacts and verify the physical performances of the subjects, under the conditions of physical fatigability, peripheral electrophysiological recordings will be necessary and complementary to meet the objectives set in this study.
OTHERElectromyogram (EMG)
In order to extract artifacts and verify the physical performances of the subjects, under the conditions of physical fatigability, peripheral electrophysiological recordings will be necessary and complementary to meet the objectives set in this study.
OTHERElectrocardiogram with 3 leads
In order to extract artifacts and verify the physical performances of the subjects, under the conditions of physical fatigability, peripheral electrophysiological recordings will be necessary and complementary to meet the objectives set in this study.
OTHERElectrodermogram (EDG)
In order to extract artifacts and verify the physical performances of the subjects, under the conditions of physical fatigability, peripheral electrophysiological recordings will be necessary and complementary to meet the objectives set in this study.
OTHERConsumption of O2 (VO2)
In order to extract artifacts and verify the physical performances of the subjects, under the conditions of physical fatigability, peripheral electrophysiological recordings will be necessary and complementary to meet the objectives set in this study.
OTHERProduction of CO2 (VCO2)
In order to extract artifacts and verify the physical performances of the subjects, under the conditions of physical fatigability, peripheral electrophysiological recordings will be necessary and complementary to meet the objectives set in this study.

Primary
| Measure | Time frame | Description |
|---|---|---|
| Identify electrophysiological markers in humans depending on whether the experimental conditions induce cognitive fatigability. | 7 hours | The evaluation of cognitive performance will be carried out by means of conventional behavioral measures, of the press-button type, handling of a mouse or of a joystick and measurement of reaction time. |
| Identify electrophysiological markers in humans depending on whether the experimental conditions induce physical fatigability with EEG. | 7 hours | Electrophysiological measurements of cerebral activity will be performed by multi-sensor electroencephalography (EEG). |
| Identify electrophysiological markers in humans depending on whether the experimental conditions induce physical fatigability with MEG. | 7 hours | Electrophysiological measurements of cerebral activity will be carried out by magnetoencephalography (MEG) |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Refine (locate at the level of the cortex), the origin of these physiological markers | 7 hours | Several types of recordings, passive and non-invasive, will be realized: * Electrooculogram (EOG); * electromyography (EMG); * electrocardiogram (ECG); Systematically in physical experiments and for some cognitive experiments. |
| Distinguish between different time scales of performance | 7 hours | Several types of recordings, passive and non-invasive, will be realized: * electrodermogram (EDG); * the consumption of O2 (VO2); * production of CO2 (VCO2). Only and systematically, in physical experiments. |
