Interactive Simulations

Manipulate. Observe. Understand.

Each simulation lets you lesion structures and watch the circuit respond in real time. Explore freely or test yourself in Quiz mode.

Ocular Motility

Eye Movement Simulator

Explore horizontal gaze pathways: PPRF, MLF, CN III, CN VI. Lesion individual structures and see the exact eye movement deficit. Includes INO, one-and-a-half syndrome, and 10-question quiz.

Open simulator
Visual Fields

Visual Field Defects

Trace the visual pathway from retina to occipital cortex. Apply lesions at any point along the pathway (optic nerve, chiasm, tract, radiation, or cortex) and see the resulting visual field loss on a Goldmann chart.

Language & Cortex

Aphasia Syndromes

Map lesion locations to aphasia type: Broca, Wernicke, conduction, global, and transcortical variants. Test fluency, comprehension, and repetition in a structured clinical framework.

Open simulator
Movement Circuits

Basal Ganglia Pathways

Manipulate dopamine levels and apply targeted lesions across the direct and indirect pathways. Load clinical presets — Parkinson's disease, Huntington's disease, hemiballismus, levodopa dyskinesia, and STN-DBS — and watch the pathways transform in real time. Includes a 27-question quiz on receptor pharmacology and circuit logic.

NeuroRace
Stroke Guidelines · Capture the Flag

A 2-player race across a 30-space Brain Track. Each turn, draw a clinical question from the 2026 AHA/ASA stroke guidelines. Answer correctly to advance — easy questions move you 1 space, moderate 2, hard 3. Land on Flag Spaces (10 & 20) to plant your flag, or steal your opponent's for a 30-point bonus. Use Jail Tokens to freeze your opponent for a turn. First to reach space 30 wins.

NeuroSnakes & Ladders
Stroke Guidelines Edition

A 2-player race across a 100-space board. Each turn, roll two dice — but you only move if you answer a clinical question from the 2026 AHA/ASA stroke guidelines correctly. Get it wrong and stay put. Land on a ladder and climb up; land on a snake and slide back. First to reach space 100 wins. Choose your question categories before you start.

Escape Room · 2026 Guidelines

StrokeCode: Escape Room
Stroke Guidelines Edition

Work through 8 richly detailed clinical cases, each with 4–6 sequential locks to break. Every lock is a question drawn from the 2026 AHA/ASA stroke guidelines. Answer correctly to advance; get it wrong and see the real patient consequence play out. Play solo, co-operate with a partner, or compete head-to-head on the same device. Points awarded per difficulty: easy 100 · moderate 150 · hard 200.
