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] GAID:621 HBA:4007 In mammals the cortex covers almost the whole of the cerebral hemispheres. In ray-finned fishes the inner surfaces of the lateral and ventral regions of the cerebrum bulge up into the ventricles. 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.

Part of the forebrain consisting of paired olfactory bulbs and cerebral hemispheres.[AAO] TAO:0000079 The anterior and dorsal forebrain neuromere, includes the olfactory bulb. Kimmel et al, 1995.[TAO] 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.
