The section is 5.52 mm rostral to the interaural plane. The dorsal lamina of the zona incerta (ZID) is coloured yellow, and the ventral lamina of the zona incerta (ZIV) is coloured green. (B) Acetylcholinesterase-stained coronal section through the caudal part of the zona incerta in a rat matched with a labelled diagram of the same section. The section is 4.20 mm rostral to the interaural plane. The caudal zona incerta is coloured red. The image and diagram are taken from the atlas of Paxinos & Watson (2007).
