Project Overview & Roadmap ### 1.1 Synopsis Brain age modelling estimates an individual's biological brain age from neurophysiological signals, with the deviation from chronological age — the **Brain Age Gap (BAG)** — serving as a quantitative biomarker of accelerated or decelerated neural ageing. Despite over a decade of methodological advancement in this field, **no published study has trained or validated an EEG-based brain age model on an indigenous African population as its primary target cohort.** This repository contains the complete, reproducible implementation for the first such study. We construct an internationally pre-trained EEG brain age regression model using a multinational, resource-constrained-setting (RCS) inclusive training corpus, and evaluate **zero-shot** and **few-shot fine-tuned** generalisation performance on the **ASZED Nigerian healthy control cohort (N = 77)** — the first open-access African EEG dataset with exact, individually reported chronological ages. > **Core Research Question:** Does a brain age regression model trained on a multinational, predominantly non-African EEG corpus generalise to a Nigerian population, what is the magnitude of the resulting cross-population generalisation gap (ΔMAE), and what is the normative Brain Age Gap distribution in healthy Nigerian adults? ### 1.2 Project Roadmap ```mermaid flowchart LR A[Multi-National Raw EEG Corpus] --> B[Harmonised Preprocessing Pipeline] B --> C[247-D Feature …
