Etymology: The Latin "cortex" meant bark, rind, or husk, as on a tree or a nut. Anatomists applied the term to the grey outer layer of the brain, which looks like a rind wrapped around the inner tissue. "Cortico-" is the combining form of that word, used in scientific compounds to mean "relating to the cortex." It is a prefix element rather than a standalone word, so it appears only inside longer terms. It attaches to other roots to name a specific part of the brain or another organ with a cortex. The adjective "cortical" comes from the same Latin base, while "cortico-" serves as the stem for compounds that describe a region or connection. Its meaning depends on the root it joins, so the exact sense in each compound comes from that second element.
