cortexrelated

Cortexrelated is a term used in neuroscience and related fields to denote phenomena, data, or research that pertain to the cerebral cortex, the brain's outer layer involved in perception, cognition, and voluntary movement. The word is a compound of "cortex" and "related" and is not a formal anatomical label in classic texts, but it appears in interdisciplinary writing, data annotation schemes, and some review articles as a convenient shorthand to distinguish cortical from subcortical phenomena.

The scope of cortexrelated work spans structural, functional, developmental, and pathological aspects of the cortex, across species and in humans. It also encompasses comparative studies that map cortical regions between primates and other mammals, as well as translational research aiming to link cortical measures to behavior.

Examples include measurements of cortical thickness, surface area, and gyrification; analyses of cortical networks and functional connectivity with fMRI; and studies of cortical plasticity and maturation. Cortexrelated concepts also arise in discussions of cortical involvement in neuropsychiatric and neurodegenerative disorders.

In data analysis, cortexrelated features are often extracted from MRI-based cortical surfaces or labeled in datasets to separate cortical from subcortical signals, and may be used to train machine learning models that predict cognitive or clinical outcomes.

Because cortexrelated is an informal label, its exact meaning depends on context. Researchers should define its scope within each study to avoid ambiguity and to facilitate cross-study comparison. See also cerebral cortex, neocortex, cortical, and neuroimaging.
