Our brief communication shows that the immature hippocampus in children is a likely active zone for postnatal neurogenesis in the dentate granular layer, indicating that our findings in rats can be applied to humans.
BRIEF COMMUNICATION 1: POSTNATAL HIPPOCAMPAL NEUROGENESIS IN CHILDREN
POSTNATAL NEUROGENESIS IN THE DENTATE GRANULAR LAYER
- labeled cells after 4 consecutive injections on P0 (birth) to P3;
- injections P4 to P7;
- injections P12 to P15;
- injections P16 to P19.
The general hypothesis we have formulated based on many correlations like these is: neurons are generated in exact sequences so that their axons and dendrites are available for innervation in the right times and places in the developing brain. Thus, the complex anatomical connections between parts of the adult nervous system are laid down during rigidly timed developmental events.
