The development and formation of the sulci on the dorsal surface of the sheep's brain.
The authors studied development of the sulci on the dorsal surface of the brain of 150 merino sheep. The sulcus coronalis was the first to appear, at a CR length of 162 mm (72-75 days). Further sulci originated in the following sequence: the sulcus ansatus at a CR length of 178 mm (76-77 days), the sulcus cruciatus at 180-183 mm (77-78 days), the sulcus marginalis at 185 mm (78-79 days), the sulcus ectomarginalis at 221 mm (85-86 days) and the sulcus endomarginalis at 265-270 mm (96-97 days). After the sulci have been formed, their development continues with accentuation of secondary branching.
