The medulloblastome is a tumour of the child relatively frequent usually sitting in the cerebellum and treated by surgery, radiotherapy and chemotherapy. After the treatment, these children present cognitive disorders and in particular disorders of the working memory associated with a fall with the school performances. By studying a troop of 32 children, we could show that the disorders of the working memory prevail during the handling of information presented visually and with verbal contents. However, the specific engagement of the cerebellum in the tasks of working memory according to the sensory method of presentation (visual or auditive) and the nature (verbal or not verbal) of information to treat vague remainder. Moreover, the anatomical attacks associated with these disorders remain ignored in these children. The best comprehension of the bases anatomo-functional calculuses which underlie their cognitive deficits is essential to develop new strategies of treatment and rehabilitation.


  • To describe in IRMf of the common and specific networks engaged during the execution of the tasks of working memory according to the sensory type and the nature of information to be memorized.
  • To describe in IRMf the cortical reorganizations necessary to the execution of the mnemic tasks among patients.
  • To describe in anatomical IRM and of the tensor of diffusion lesions cérébelleuses and cerebral, cortical and subcortical associated with these disorders.
  • To study the correlations radio-private clinics between data IRM and the data neurological and neuropsychological of the children explored according to protocol ONCORAP

Groups/Cohorts Assigned Interventions
healthy volonteer children
paired for the sex and the age
Other: IRMf Bold
IRMf BOLD of the working memory
older children followed for a médulloblastome cérébelleux
children followed for a médulloblastome treaty by surgery, radiotherapy and chemotherapy
Other: IRMf Bold
IRMf BOLD of the working memory

Detailed Description:
The functional study should make it possible to show the specifically committed networks according to the cognitive tasks. Among patients, the relative difficulty to carry out the tasks of working memory should be accompanied by a recruitment of the dorso-side cortex préfrontal, lower and parietal frontal cortex but also of the median frontal areas such as the additional driving surface, the former cingulum. Moreover, one deterioration of the engagement of the cérébello-cerebral network (left lower parietal cortex and cérébelleux cortex lower right) facilitating the execution of these tasks should be observed.
