Brief summary: IRMaGe is a Joint Service Unit (UMS) which provides users of brain exploration equipment (clinical MRI and preclinical, TMS, EEG, NIRS and metabolomics). The methods available on this equipment are intended to evolve according to the most recent discoveries and this protocol aims to frame the developments necessary around clinical MRI for IRMaGe can continue to offer tools at the cutting edge of technology.

Detailed description: The studies will be carried out on healthy subjects and voluntary patients, who will have given their consent. Their main objective will be the development and optimization of sequence parameters or design stimulation paradigms in order to optimize the quality and relevance of the images produced taking into account the parameters anatomical, functional or metabolic while respecting the experimental constraints imposed by the protocol concerned (equipment of experimentation, additional physiological measurements, etc.). The main judgement criteria will be measurements inherent in the MRI sequence and a physiological measurement associated in the protocol concerned

Eligibility criteria: Inclusion Criteria:

* Participants with normal or corrected vision
* Participants affiliated to a social security scheme or beneficiaries of such a scheme
* Participants with French as their mother tongue
* Participants who have given the signed informed consent before carrying out any procedure related to the study.
* Volunteer patients will be recruited as part of their follow-up at the CHU. Their pathology will be in agreement with that of the research protocol to be optimized.

Exclusion Criteria:

Criteria relating to contraindications to the explorations provided for by the MRI protocol:

* metallic glitter in the eyes
* retinal operation
* claustrophobia
* wearer of pacemaker or cardiac defribrillator or vascular clip or prosthesis cardiac or insulin pump or implanted device to deliver medication or hearing implant or prosthesis or vascular shunt or paragraph or screws, plate metal or tattoo or piercing or implanted metal object or lead shot hunt

  * Alcohol ingestion before the examination
  * Pregnant, lactating and parturient women
  * Major protected by law
  * Participants under administrative or judicial supervision
  * Participation in another ongoing study if the study may interfere with participation in the protocol MAP-IRMaGe.
