You have cell bodies found in the cerebral cortex. That is why it looks gray in colour.
Cerebral Cortex
All of the cerebral cortex is gray matter as it composed of neuronal cell bodies which are not insulated with myelin.
Reticular formation
The few islands of gray matter within the interior of the cerebrum are made up of neuron cell bodies and unmyelinated axons. These areas of gray matter act as the central processing unit of the brain. Many things can affect this gray matter, such as, smoking, child abuse, alcoholism, and drugs.
== == In short, the cerebral cortex is the outer and largest part of the brain, that covers its smaller parts and is usually easily visible on brain illustrations. It contains gray matter (neurons) responsible for the "higher" functions of thinking and information processing. There's also a lot of information about the cerebral cortex on http://www.answers.com/cerebral+cortex
The cerebral cortex is the outer layer of thecerebrum, it is composed of six cell layers of deeply folded and ridged gray matter.
Cerebral Cortex
The cerebral cortex is actually the covering layer. It is a thin layer of tissue that covers the part of the brain called the cerebrum.
Grey matter is distributed at the surface of the cerebral hemispheres (cerebral cortex) and of the cerebellum (cerebellar cortex), as well as in the depths of the cerebrum (thalamus; hypothalamus; subthalamus, basal ganglia - putamen, globus pallidus, nucleus accumbens; septal nuclei), cerebellar (deep cerebellar nuclei - dentate nucleus, globose nucleus, emboliform nucleus, fastigial nucleus), brainstem (substantia nigra, red nucleus, olivary nuclei, cranial nerve nuclei) and spinal grey matter (anterior horn, lateral horn, posterior horn).

cerebrum's outer layer of gray matter, the cerebral cortex.
The cerebral cortex is composed of neuron cell bodies which lack the fatty white myelin sheaths around the axons and so is sometimes referred to as gray matter.
Cerebral cortex.
The cerebral cortex
A thin layer of gray matter called the cerebral cortex comprises the outer portion of the cerebrum.
