Tomasz Adamusiak XAO:0000012 The telencephalon is the name for a large region within the brain that is attributed many functions. Many people refer to it as the cerebrum; however, it is technically referred to as the telencephalon. As a more technical definition, the telencephalon refers to the cerebral hemispheres and other, smaller structures within the brain, although the telencephalon is one of the larger divisions (in terms of number). It is the anterior-most embryological division of the brain that develops from the prosencephalon. The telencephalon is composed of the following sub-regions; Limbic system; Cerebral cortex or cortices of the cerebral hemispheres, Basal ganglia, Olfactory bulb. The telencephalon comprises what most people think of as the "brain." It lies on top of the brainstem and is the largest and most well-developed of the five major divisions of the brain. The telencephalon is the newest structure in the phylogenetic sense, with mammals having the largest and most well-developed among all species. It emerges from the prosencephalon, the first of three vesicles that form from the embryonic neural tube (Christine Fennema-Notestine). 2.38 TAO:0000079 EHDAA:3496 The anterior and dorsal forebrain neuromere, includes the olfactory bulb. Kimmel et al, 1995. The anterior and dorsal forebrain neuromere. In ray-finned fishes and most pronounced in teleosts the roof plate of the embryonic telencephalon extends laterally with the effect that the paired alar plates forming the hemispheric walls roll out lateroventrally in a process called eversion. This is unlike the development in other vertebrate groups. From Neuroanatomy of the Zebrafish Brain.
