Female rodents also exhibit another cortical layer called the "X zone" whose function is not yet clear.

"But that's not correct," she said, "because only some of the cortical layers show the difference."

Some people walk around with gray matter full of nodules or with cortical layers that are upside down.

The other 50 percent with the malformation have a mixture of normal and abnormal cells, making it difficult to see distinct cortical layers.

The amygdaloid complex comprises both nuclear and cortical layers.

These columns are located in the primary visual cortex and span multiple cortical layers.

The term pellis refers to the cellular cortical layers of a mushroom.

These projections preferentially go to cortical layer I neurons.

In humans the six cortical layers of area 10 have been described as having a "remarkably homogeneous appearance".

They are covered with a cortical layer with a convoluted topography.
