The telencephalon of S. tsinlingensis was consisted of paired olfactory bulbs, paired cerebral hemispheres, and a telencephalon medium or impar. Main-olfactory bulb can be classified into six layers such as olfactory nerve fibers layer, glomerular layer, external plexiform layer, mitral layer, internal plexiform layer, granular layer and ependyma layer. The dorsal part of telencephalon contained the cortex and dorsal ventricular ridge. The cerebral cortex of S. tsinlingens was relatively thin, while the dorsal cortex was the thinnest, but gradually thickened as it extended to the medial and lateral cortex. The neural cells, glial cells and ependymal cells widely distributed in the cerebral cortex represented similar ultrastructural characteristics to those described in other vertebrates. Golgi staining revealed multipolar cell, bitufted cell and monotufted cell in three cortical layers of medial cortex. The results indicated that the cytoarchitectonic characteristics of telencephalon in S. tsinlingensis resembled those found in other lizards.
