What cells does the cerebral cortex include?
Two sorts of neurons are acknowledged within the cerebral cortex: excitatory (glutamatergic, pyramidal, or efferent) and GABAergic (interneurons or native circuits). These cell sorts are interconnected and organized in tangential (laminar) and columnar (translaminar) configurations.

What’s the cerebellar cortex?
Grey matter that kinds the overlaying of the cerebellum. It has a lot of high-quality grooves separating the cerebellar lamellae and consists of three layers of neurons: molecular, Purkinje cell and granular.
