| Week | Carnegie Stage | Event |
|---|---|---|
| week 4 | 11 | nasal epiblastic thickening appears |
| 12 | nasal field is well outlined | |
| {CS15}} | continuous cellulovascular strand seen between the nasal groove and the olfactory field | |
| 16 | vomeronasal groove appears at stage (O'Rahilly 1967). | |
| 17 | olfactory nerve is organized into two plexuses, lateral and medial, the latter mingled with the terminal-vomeronasal complex. | |
| 18 | olfactory bulb begins to appear | |
| 19 | individualization of the olfactory bulb and nuclei. Distinction between olfactory structures and terminal and vomeronasal ones begins to be clear | |
| 21 | structure of the olfactory bulb is evident. | |
| 23 | olfactory strands are well individualized, and olfactory and terminal-vomeronasal fibers are easily distinguishable. | |
