Telencephelon

• The teleoncephelon consist of the cerebral hemisphere, basal nuclei and olfactory bulb.
• In primitive vertebrates, the cerebral hemisphere are mainly involved with olfaction and related motor responses.
• ın higher vertebrates the gray matter of the cerebral hemisferes, except for the basal ganglia is moved to the surface, forming the cerebral cortex.
• In mammals, the cortect forms the majority of the cerebral hemispheres.
• The cortext has convulated surface and many neurons.
