INTRODUCTION: The human nervous system is the most complex, widely investigated and yet poorly understood physical system known to mankind. The study of the development of human brain in utero is possible with investigations like ultrasound scanning and magnetic resonance imaging during pregnancy. At what week of gestation which part of brain is forming is known now. Progress of neuronal growth is assessed. It follows a predictable timetable.
AIM: The aim is provide certain anatomical standards of neural developmental growth comparing already available imaging studies by physical dissection of fetuses and adult brains.
MATERIAL AND METHODS: 50 fetuses (from 20 weeks of gestation) and 10 adult brains were dissected, formalin prepared and studied. Weight and volume also recorded.
OBSERVATIONS: Are tabulated.
SUMMARY AND CONCLUSIONS: Results are comparable with results of imaging studies.
