Reason (R) It is due to the high concentration of neuron cell bodies in it.

Neural Control and Coordination

Solution:

Assertion is false, but Reason is true and Assertion can be corrected as
The layer of cells which covers the cerebral hemispheres is called cerebral cortex and is thrown into prominent folds. It is referred to as the grey matter. It is called grey matter due to its greyish appearance. Neuron cell bodies are concentrated here which give it the greyish appearance.
