IDEALE aims to assess the status of autonomic function, cerebral autoregulation (CA) and cortical activity in healthy subjects and correlate these functions with the psychological dimension of the subjects. To this end, parameters of cardiac, cortical, vascular and cerebrovascular variability derived from electrocardiographic, electroencephalographic, respiratory movement, blood pressure, transcranial Doppler signals will be acquired and analysed for each healthy volunteer (TCD) and Laser-Doppler transcutaneous, during a phase of clinostatism (REST) and one of active orthostatism (STAND). In addition, volunteers will be submitted to psychometric tests (Chieti Affective Action Videos, CAAV) to assess the presence of depressive symptoms.

RECRUITINGAutoregulation index (ARI)
ARI is an index describing the state of cerebral autoregulation from mean cerebral blood velocity and mean arterial pressure. Minimum value 0, maximum value 9. ARI\>4 means working autoregulation. ARI\<4 means impaired autoregulation. It will be computed for all participants.
Time frame: 36 months
Baroreflex sensitivity
Baroreflex sensitivity will be measured in ms/mmHg. Minimum value 0. Higher value means a better baroreflex regulation. It will be computed in all participants
Time frame: 36 months
Cortical activity
Power of EEG in Alpha and Beta band will be measured in square microvolt. Minimum value 0.
Time frame: 36 months
