Background: During intrauterine life brain surface is smooth up to 14th week. The cortical maturation and vascularisation of lateral surface of the brain starts with the insular region, suggesting that this region is the central area of cortical development between temporal and frontal lobe. Delayed sulcation during pregnancy leads to agenesis of corpus callosum along with additional brain abnormality.
Materials: This study was conducted on 50 dead foetuses in anatomy department brought from the department of Obstetrics and gynaecology.
Results: Brain is divided into two half by appearance of median longitudinal fissure between 12-14weeks. The surface of each cerebral hemisphere is smooth up to 4th month, later surface depression appears on the supero lateral surface at 5th month. Growth of adjoining lobes of brain make surface more convoluted ,and at 6th month sulcus make their appearance .All important sulci are laid down by the end of 7th-8th month.
Conclusion: There is no differences between male and female brains of same gestational age. Knowledge of the sulci enlightens us regarding treatment and protection of vital structures.
KEY WORDS: Cortical maturation, Sulci, Gestational age, Foetal brain.
