What is in the cerebral cortex?

In the cerebral cortex there are 6 layers of neurons (grey matter).


Thin outer layer of gray matter in the brain?

The cerebral cortex is the outer layer of thecerebrum, it is composed of six cell layers of deeply folded and ridged gray matter.


What is found in the gray matter of the cerebral cortex?

You have cell bodies found in the cerebral cortex. That is why it looks gray in colour.


Where is white matter not found?

Cerebral Cortex.


Are unmyelinated axons in the cerebral cortex?

The cerebral cortex contains the bodies of neurons which appear grey (grey matter). The layer under the cortex contains myelinated axons (white matter).


The complex network of tiny islands of gray matter within the brain that activates the cerebral cortex to a state of wakefulness is the?

Reticular formation


What is the gray matter on the surface of the brain called?

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).


What forms the outer layer of the 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.


What does the cerebral cortex cover?

The cerebral cortex is the outer layer of the cerebrum, or large brain. It also is where most of the grey matter, i.e. neuronal cell bodies, are found. So you could say that the cerebral cortex covers the white matter of the cerebrum.


What is responsible for communication between cerebral areas and between the cerebral cortex and lower CNS centers?

The cerebral white matter


Thin layer of gray matter on surface of cerebrum?

Cerebral Cortex


What does the cerebral cortex compose of?

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.
