CEREBRAL MATURATION AND FUNCTIONAL IMAGING

摘要: Normal cerebral maturation and therefore development of sensory cognitive functions are sustained by neurobiological changes that better known in animals than humans. Postnatal developmental can now be approached humans means non-invasive methods using external detection brain signals. These functional imaging techniques include PET (positron emission tomography), SPECT (single photon computed tomography) fMRI (functional magnetic resonance imaging). recently experienced rapid for stimulation studies because they detect localize the activation produced selective tasks. Unfortunately, technical constraints make such almost impossible to realize children. also measure at rest, respectively local metabolism glucose regional blood flow, both parameters being proportionally close neuronal activity same region. “at rest studies” available young children used pathological conditions as childhood epilepsy or disorders. Most data about postnatal have been obtained studies”. They advantage providing measures level. It is interesting correlate flow during with
