Study Notes
Brain Development During Fetal Period
- Brain surface is smooth in the embryonic period.
- At birth, the brain has folds (gyri and sulci).
- Gyri and sulci development occurs during the last trimester of pregnancy.
- MRI and high-resolution ultrasound can visualize gyri and sulci in developing fetuses.
- MRI allows detailed visualization of grey matter (cell bodies) and white matter (myelinated axons).
- A newborn's brain is 30% the size of an adult brain.

Description
Test your knowledge on brain development during the fetal period. This quiz explores key changes such as the transition from a smooth brain surface to the formation of gyri and sulci. Understand the importance of MRI and ultrasound in visualizing these developments.
