The Caudate Nucleus begins just behind the frontal lobe and curves back towards the occipital lobe. It is an elongated C-shaped mass of gray matter with large rounded head, curved body and long slender tail. It is closely related to the lateral ventricle. Around the rostral border of the internal capsule, it is fused with the putamen of the lentiform nucleus while its tail terminates in close relationship to the amygdala. It sends its messages to the frontal lobe (especially the orbital cortex, just above the eyes).
