Scientific notes
Libelle of note
Traditionally, the Mesencephalon was subdivided into the Tectum (the Colliculi) and the Pedunculus (the Crus cerebri, the Substantia.VTA complex and the Tegmentum mesencephali). Here it is advocated to use the term Pedunculus only for what it actually is: a large bundle of fibres from the Telencephalon to the Brain stem and Spinal cord.
