In reptiles the septal area is located in the medial wall of the telencephalon. It can be divided into 2 subregions: the precommissural septum and the postcommissural septum. The dorsal portion of the precommissural septum (PDS) received a massive projection from the medial cerebral cortex. It can be distinguished from the other portions of the pre- and postcommissural septum by its Timm-positivity and by its positivity to acetylcholinesterase histochemistry.
