What does cortically mean?
"Cortically" is the adverbial form of "cortical", meaning in a manner that involves or originates in the cerebral cortex — the deeply folded outer layer of the brain responsible for higher functions such as perception, movement, language, and conscious thought. It belongs firmly to the vocabulary of neuroscience and clinical medicine, where precision about the anatomical level of a process matters: a tremor may be described as cortically generated, a sensory response as cortically mediated, or cognitive processing as cortically organized, each phrasing signalling that the cortex — and not deeper, subcortical structures such as the brainstem or basal ganglia — is the relevant site. Because it carries this technical weight, the word seldom appears outside specialist literature, and writers aiming at a general audience usually prefer plain adjectives like "brain-based". Its root, Latin "cortex", meaning bark or rind, evokes the way the cortex forms a thin outer sheath over the brain's interior.
adverbIn a manner relating to the cerebral cortex, the outer layer of the brain; used especially in medicine and neuroscience to describe functions or conditions arising from or located in the cortex.
- Relating to or involving the cerebral cortex, especially as the site or origin of a physiological or psychological process (e.g., cortically mediated responses).
"The patient's vision loss was cortically mediated rather than caused by damage to the eyes themselves."
"The tremor was judged to be cortically generated after imaging revealed abnormal activity in the motor cortex."
"Some aspects of visual awareness appear to depend cortically on regions far beyond the primary visual area."

Etymology of cortically
The word derives from "cortical", the adjective form of "cortex", a Latin noun originally meaning bark, rind, or shell. When anatomists adopted the term, they applied it metaphorically to the outer layer of organs, most famously the cerebral cortex — literally the 'bark' of the brain. The adverb "cortically" formed regularly from this adjective, following the standard English pattern of adding the suffix -ly. Its closest relatives share the same Latin root: "cortex" itself, "cortical", and derived compounds such as "subcortical" and "corticosteroid".

How cortically is actually used
A technical term confined almost entirely to medical, neurological, and scientific writing; it rarely appears in general prose. It typically modifies verbs such as "mediated", "driven", "generated", or "organized" to specify that a process originates in or depends upon the cortex rather than subcortical structures.
Easily confused with cortically
"Cortical" is the adjective describing something pertaining to the cortex, while "cortically" is its adverbial form describing how an action or process occurs in relation to the cortex.
"Cardiac" relates to the heart, whereas "cortically" relates to the cerebral cortex of the brain; the two are sometimes confused only because both derive from Latin terms for an outer layer or husk-like structure.
