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]. The anterior and dorsal forebrain neuromere, includes the olfactory bulb. Kimmel et al, 1995.[TAO] Part of the forebrain consisting of paired olfactory bulbs and cerebral hemispheres.[AAO] |

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] |

In ray-finned fishes the inner surfaces of the lateral and ventral regions of the cerebrum bulge up into the ventricles. 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. 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. In the most primitive living vertebrates, the hagfishes and lampreys, the cerebrum is a relatively simple structure receiving nerve impulses from the olfactory bulb. |
