Carnegie Stage 21 |
The movies below show anatomical domains defined in the N496 model. The domains have been manually defined in the OPT models using specialised software and then visualised using commercial rendering packages.
The various domains are: neural tube - orange; eye - dark blue; otic vesicle - yellow; dorsal root ganglia - cyan.
