Abstract
Understanding the clinical outcomes of brain lesions necessitates knowing the
networks of cerebral structures that constitute the substratum of cognitive or
sensorimotor functions. This is achieved by interpreting activation data obtained,
during the performance of a task, through functional neuroimaging techniques.
The difficulty is that no one-to-one correspondence between activated networks
and functions can be found. Actually, neuroimaging methods aim at analyzing
specifically the activation. They are used to localize spatially and temporally the
activated areas, to detect the different areas participating in the same function,
and to determine the role of anatomical links on the activation. Clearly, an
interpretative method explaining how the activation of large-scale networks
derives from the cerebral information processing mechanisms involved in the
task performan
