When neuroscientists talk about gray matter, they refer to parts of brain consisted of neuron bodies. Grey matter is where the impulses in your brain are generated.

There are different areas of gray matter in the brain, the biggest one is the cortex, it is the outermost layer of your brain and is around the size of a napkin when unfolded. Other than your cortex, there are different areas or islands of gray matter with different functionalities, check out the “Grey Matter Structures” of your brain map to learn more about them.
