Key milestones in fetal brain development
| Weeks pregnant | Milestone |
|---|---|

When does the brain start to move in early pregnancy?
First trimester: Baby starts moving. Once the neural tube closes, at around week 6 or week 7 of pregnancy, it curves and bulges into three sections, commonly known as the forebrain, midbrain and hindbrain.
