With almost 90 billions neurons, the human brain fundamentally differs from that of other species not only because of its size and the high number of its neuronal connections, but also through the tremendous expansion of its cortex, the kind of progenitors involved in its growth, the time required to achieve its expansion and maturation and the activation of human-specific genes. Key steps of brain development are critical to the cognitive outcome of the future child and constitute potential windows of vulnerability targeted either by pathogens or by genetic mutations.
