cerebral cortex

the layer of gray matter that covers the outside of the cerebral hemispheres in the brain and is associated with higher cognitive functions, such as language, learning, perception, and planning. It consists mostly of neocortex, which has six main layers of cells (see cortical layers); regions of cerebral cortex that do not have six layers are known as allocortex. Differences in the cytoarchitecture of the layers led to the recognition of distinct areas, called Brodmann’s areas, many of which are known to serve different functions.

law of contrast

law of contrast

a principle of association stating that opposites are reminders of one another: encountering or thinking about one (e.g., a snow-covered field) tends to bring to mind the other (e.g., a sunny beach). Initially proposed as a distinct, essential concept in associationism, the law of contrast later came to be viewed as a special case of the law of contiguity.
