BRAIN-DEVELOPMENT OF TYPHLONECTES COMPRESSICAUDUS

The development of the brain of Typhlonectes compressicaudus (Amphibia , Gymnophiona) has not been described. Brain development of Typhlonect es compressicaudus includes three phases: a phase of proliferation (th e volume of neural epithelium increases), a phase of differentiation ( neurons develop extensions), and a phase of maturation. These three ph ases are similar to other vertebrates. In this study, the embryonic st ages of the brain are described and compared with brain development of other amphibians and some reptiles.
