Syntax (parts of speech) is ten (10) items: adjective, adverb, article, conjunction, interjection, noun, numeral, preposition, pronoun, verb. What follows is a syntax of electroencephalography (EEG).
Here is the standard neurolinguistic mapping between EEG electrodes, Brodmann areas, and the Broca–Arcuate Fasciculus–Wernicke network:
🧠 Broca–AF–Wernicke Language Pathway (EEG ↔ Cortex)
EEG Electrodes (10–20)
Function
Cortical Region
Brodmann Areas
Broca’s area (speech production, syntax)
Inferior frontal gyrus (pars opercularis & triangularis)
BA 44, 45
F7, F5, FC5
Premotor speech planning
Ventral premotor cortex
BA 6
FC5, F5
Arcuate fasciculus (white-matter tract)
Connects frontal ↔ temporal
— (no BA, fiber tract)
Functional connectivity between F7 ↔ T7
Wernicke’s area (speech comprehension)
Posterior superior temporal gyrus
BA 22
T7, TP7
Auditory association
Middle temporal gyrus
BA 21
T7, TP7
Angular gyrus (semantic integration)
Inferior parietal lobule
BA 39
P7
Supramarginal gyrus (phonology)
Inferior parietal lobule
BA 40
CP5, P5
EEG Functional Connectivity Interpretation
In EEG studies of language:
Broca ↔ Wernicke coherence = F7 ↔ T7 phase coupling
This operationalizes the arcuate fasciculus in EEG space.
Beta/gamma coherence → speech production & phonology
Theta/alpha coherence → lexical–semantic integration
One-line Mapping
Broca (BA44/45 → F7) — AF (F7↔T7 coherence) — Wernicke (BA22 → T7).
