EEG 10-20 System Learning App

A lightweight interactive application designed to help medical students, neurologists, and clinical researchers memorise the standard EEG 10-20 Electrode Placement System.

🧠 Features

• Explore Mode: Hover over or tap any electrode on the top-down head map to instantly see its specific clinical label (e.g., Fp1, Cz, O2).
• Quiz Mode: Test your knowledge! The app highlights a random electrode and provides multiple-choice options.
• 10-Spot Evaluation: Each quiz round consists of exactly 10 questions.
• Negative Marking: To encourage precision, correct answers grant +1 point, while incorrect guesses penalise you with -1 point.

🚀 How to Use 

• To Learn: Stay in "Explore Mode" and move your mouse over the various circles on the head diagram to learn where each 10-20 coordinate lives. Note that the triangle at the top represents the nose, and the curves on the side represent the ears.
• To Test Yourself: Click the "Quiz Mode" button. Select the correct label for the blue highlighted electrode. Keep an eye on your score at the bottom—wrong answers will cost you points!
