[Functional organization of the brain cortical areas at rest condition in children 5, 6 and 7 years old].

Functional connectivity at rest was studied in children of 5, 6 and 7 years old. Connection strengths were estimated using coherence function taken at the frequencies of the major EEG rhythms. Factor analysis of the raw coherence data revealed 4 different cortico-cortical functional connectivity patterns. These patterns are stable across the studied age span although particular functional links may change reflecting the general trend of heterchronous maturation of the cortex.
