The development of the motor component of the embryonic and fetal central nervous system can be studied by observation of fetal movements, using real-time ultrasound. In this paper data on emergence and development of fetal movement patterns and behavioural states are reviewed in the light of the normal development of the nervous system, identification of disturbances in normal development and testing behavioural teratogenicity in the human.
