In adults, motion perception is mediated by an extensive network of occipital, parietal, temporal, and insular cortical areas. Little known about the neural substrate visual in infants, although behavioural studies suggest that rudimentary at birth matures steadily over first few years. Here, measuring Blood Oxygenated Level Dependent (BOLD) responses to flow versus random-motion stimuli, we demonstrate major areas serving processing adults are operative 7 wk age. Resting-state correlations adult-like functional connectivity between motion-selective associative areas, but not primary cortex temporo-occipital posterior-insular cortices. Taken together, results development may be limited slow maturation subcortical input cortico-cortical connections. addition they support existence independent (V1) (V5/MT+) cortices very early life.
