relationship loss: develops_from presumptive telencephalon (TAO:0000571)[TAO]

Part of the forebrain consisting of paired olfactory bulbs and cerebral hemispheres.[AAO], The anterior and dorsal forebrain neuromere, includes the olfactory bulb. Kimmel et al, 1995.[TAO], Organ component of neuraxis that has as its parts the cerebral cortex, cerebral white matter, basal ganglia, septum and fornix, as well as subcortical gray and white matter structures[FMA:62000].

From an evolutionary standpoint, the telencephalon is the most recent brain structure: the amphioxus does not have this structure as a morphological entity. Overt telencephalon is present in the hagfish and lamprey to receive numerous input fibers from various parts of the CNS, similar to gnathostomes.[well established][VHOG]

UBERON:0001893

In ray-finned fishes the inner surfaces of the lateral and ventral regions of the cerebrum bulge up into the ventricles., 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. [ZFA:0000079, ISBN:3764351209], In the most primitive living vertebrates, the hagfishes and lampreys, the cerebrum is a relatively simple structure receiving nerve impulses from the olfactory bulb., In the amniotes, the cerebrum becomes increasingly large and complex. In reptiles, the paleopallium is much larger than in amphibians, and its growth has pushed the basal nuclei into the central regions of the cerebrum., The cerebrum of birds has evolved along different lines to that of mammals, although they are similarly enlarged, by comparison with reptiles. However, this enlargement is largely due to the basal ganglia, with the other areas remaining relatively primitive in structure., dolphins are the only species (other than humans) to have cerebra accounting for as much as 2 percent of their body weight., In mammals the cortex covers almost the whole of the cerebral hemispheres.
