Collection: Brain of the reptilians (Reptilia)

Species: Agama sanguinolenta (Pallas, 1814)    Reptilia

Description: Frontal (transverse) paraffin section through a telencephalic hemisphere of the steppe agama Agama sanguinolenta (Pallas, 1814) stained with cresyl viotet by the Nissl method. The section shows the overall cytoarchitecture of a hemisphere of a lizard. The section also shows how the true cortical structure begins to be formed in the pallial structures (neurons detach from the surface of the ventricle and form a distinct cortical layer in the dorsal regions of the hemisphere). The reptiles are the first vertebrates to form the true cortical plate (the forerunner of the mammalian cortex).
