Brief Summary:
Pain is complex phenomenon misunderstood in spite of medical progress and neurosciences. That's why the relief of chronic pain is only partial for a lot of infection as arthrosis, chronic back pain, headaches or neuropathic pain. Certain situations bring to relive pain sensation. Investigators were interested to former burned. They wonder about somatic memory and unconscious of acute.

Condition or disease Intervention/treatment Phase
Magnetic Resonance Imaging Neuronal Activity Other: fMRI Not Applicable

Detailed Description:

It is a comparative and monocentric study. There are two groups. On the one hand, there is the former burned and, on the other hand, healthy volunteers. While they thought to painful memory or not, functional Magnetic Resonance Imaging (fMRI) will be performed. Then, investigators compare two functional Magnetic Resonance Imaging (fMRI).

Main objective of this study is link up between brain activity by functional Magnetic Resonance Imaging (fMRI) and acute pain memory.

Arm Intervention/treatment
Experimental: patients
Patient who was burned will have fMRI.
Other: fMRI
During fMRI, patients and control group will have to thought to seven painful memories, seven emotional memories not painful, seven neutral memories. At every memory there is control test. It is to count backwards.
Other Name: functional Magnetic Resonance Imaging (fMRI)

Active Comparator: control group
Healthy volunteers (control group) will have fMRI.
Other: fMRI
During fMRI, patients and control group will have to thought to seven painful memories, seven emotional memories not painful, seven neutral memories. At every memory there is control test. It is to count backwards.
Other Name: functional Magnetic Resonance Imaging (fMRI)




Primary Outcome Measures :
  1. BOLD (blood-oxygen-level dependent) signal between painful memories [ Time Frame: Months 3 ]
    Correlation between BOLD measured by functional Magnetic Resonance Imaging (fMRI) and every conditions: painful memories, emotional memories not painful, neutral memories and control test.

  2. BOLD (blood-oxygen-level dependent) signal between emotional memories not painful [ Time Frame: Months 3 ]
    Correlation between BOLD measured by functional Magnetic Resonance Imaging (fMRI) and every conditions: painful memories, emotional memories not painful, neutral memories and control test.

  3. BOLD (blood-oxygen-level dependent) signal between neutral memories [ Time Frame: Months 3 ]
    Correlation between BOLD measured by functional Magnetic Resonance Imaging (fMRI) and every conditions: painful memories, emotional memories not painful, neutral memories and control test.

  4. BOLD (blood-oxygen-level dependent) signal between control test. [ Time Frame: Months 3 ]
    Correlation between BOLD measured by functional Magnetic Resonance Imaging (fMRI) and every conditions: painful memories, emotional memories not painful, neutral memories and control test.


Secondary Outcome Measures :
  1. BOLD (blood-oxygen-level dependent) signal between control group for every conditions [ Time Frame: Months 3 ]
    Correlation between BOLD measured by functional Magnetic Resonance Imaging (fMRI) and groups for every conditions: painful memories, emotional memories not painful, neutral memories and control test.

  2. BOLD (blood-oxygen-level dependent) signal between patients for every conditions [ Time Frame: Months 3 ]
    Correlation between BOLD measured by functional Magnetic Resonance Imaging (fMRI) and groups for every conditions: painful memories, emotional memories not painful, neutral memories and control test.
