The human brain undergoes gyrification during fetal and neonatal development. Therefore, ITP is a significant cause of fetal and neonatal immune thrombocytopenia. This approach can also be used to study chromosomal aberrations in fetal and neonatal genomes. It increases the morbidity as a cause of neonatal infections. It is a risk factor for neonatal sepsis. It is most active in fetal and neonatal life. Developmental changes in synaptic properties in hippocampal neonatal rats.
