“Telencephalon” is a term borrowed from embryology to identify not only the cerebral hemispheres of the forebrain, but also the basal forebrain. We review a generally undercited literature that...
28 Αυγ 2023 · This chapter describes the anatomic and functional components of the telencephalon, and provides a brief overview of the development and anatomy of the telencephalon. It identifies the ventricular structures of the telencephalon and the external features of the telencephalon.
During ontogeny, the telencephalic hemispheres evaginate bilaterally from the dorsalmost alar plate of the secondary prosencephalon (Figs. 2.2 C, 2.3 C, 2.4, 2.5 B,C). There are two principal divisions of the telencephalic hemispheres: the roof or pallium and the basis or subpallium.
In elasmobranchs, as in tetrapods, the telencephalon develops by evagination, a morphogenetic process which implies protrusion toward the outside and expansion of the lateral telencephalic walls. The telencephalon is subdivided into telencephalic hemispheres and olfactory bulbs.
21 Αυγ 2024 · The cerebrum, also called the telencephalon, refers to the two cerebral hemispheres (right and left) which form the largest part of the brain. It sits mainly in the anterior and middle cranial fossae of the skull.

17 Ιουν 2020 · The review summarizes and analyzes the data accumulated in recent years from studies of the genetic mechanisms of early telencephalon development in lower vertebrates and searches for telencephalon homologs in two vertebrate-related chordate groups, Cephalochordata and Tunicata.
