|---|---|---|
| Week | Carnegie Stage | Event |
| Stage 11 - appearance of the optic ventricle. The neural groove/tube space is initially filled with amniotic fluid. | ||
| Stage 12 - closure of the caudal neuropore, onset of the ventricular system and separates the ependymal from the amniotic fluid. | ||
| Stage 13 - cavity of the telencephalon medium is visible. | ||
| Stage 14 - cerebral hemispheres and lateral ventricles begin, rhomboid fossa becomes apparent. | ||
| Stage 15 - medial and lateral ventricular eminences cause indentations in the lateral ventricle | ||
| Stage 16 - hypothalamic sulcus is evident. | ||
| Stages 17-18 - interventricular foramina are becoming relatively smaller, and cellular accumulations indicate the future choroid villi of the fourth and lateral ventricles. | ||
| Stage 18 - areae membranaceae rostralis and caudalis are visible in the roof of the fourth ventricle, and the paraphysis is appearing. | ||
| Stage 19 - choroid villi are visible in the fourth ventricle, and a mesencephalic evagination (blindsack) is visible | ||
| Stage 20 - choroid villi are visible in the lateral ventricle. | ||
| Stage 21 - olfactory ventricle is visible. | ||
| Stages 21-23 - lateral ventricle has become C-shaped (anterior and inferior horns visible). Recesses develop in the third ventricle (optic, infundibular, pineal). | ||
