About the Brain Seizure Simulation

⚠️ Important Medical Disclaimer

This is a simplified educational simulation, not medical information.

• This tool does not provide medical advice, diagnosis, or treatment recommendations

• Real seizures vary greatly in appearance and effects - many have subtle or no visible signs

• Seizures are serious medical events requiring proper emergency response and medical care

• If you or someone you know experiences seizures, consult qualified medical professionals

• This simulation does not replace proper medical education or first aid training

• Contains flashing effects that may trigger photosensitive seizures

Overview

This interactive simulation provides a simplified visual and auditory representation of different types of brain seizures. It is designed as an educational tool to help users understand the basic concepts of seizure activity and how various seizure types can manifest differently within the brain.

Note: This simulation represents highly simplified models of complex neurological processes. Real seizure activity involves intricate patterns of neural activity that cannot be fully captured in this visualization.

How to Use

Use the controls located at the top-right of the simulation window:

  • Seizure Type: Select a specific type of seizure from the dropdown menu.
  • Start Simulation: Click this button to initiate the simulation for the selected seizure type. The information panel on the right will update to describe the "Before," "During," and "After" stages.
  • Play Demo: Click this button to automatically cycle through all available seizure types. The simulation will play each type sequentially. Click "Stop Demo" to interrupt the cycle.
  • Enable Sound: Check this box to activate auditory feedback corresponding to the simulated brain activity. (Requires user interaction to start audio context in some browsers).

Seizure Types Explained

Focal Seizures

Focal seizures start in one area of the brain and may spread over time. The simulation shows a growing area of abnormal activity originating from a specific focus point.

Generalized Tonic-Clonic

This seizure type has two phases: the tonic phase causes muscle stiffening, followed by the clonic phase of rhythmic jerking. It represents widespread, chaotic brain activity affecting both hemispheres.

Absence Seizures

Absence seizures are brief, sudden lapses of awareness, represented by a global pause or 'freeze' in activity with a characteristic 3Hz spike-and-wave pattern.

Tonic Seizures

Cause sudden muscle stiffening, often leading to falls. The simulation shows sustained, intense brain activity that gradually builds up.

Atonic (Drop) Seizures

Sudden loss of muscle tone causing collapse. Also called "drop attacks." The simulation shows a rapid decrease in brain activity and particle "dropping."

Myoclonic Seizures

Brief, shock-like muscle jerks. Often occur in clusters. The simulation shows rapid, intermittent bursts of brain activity with jerky particle movements.

Understanding the Visualization

Color Coding

  • Seizure activity: Colors transition from yellow to red based on intensity.
  • Baseline colors: Different colors represent the four major lobes of the brain (frontal, parietal, temporal, occipital).

Movement Patterns

  • • Generalized seizures: Widespread, high-frequency vibrations followed by strong, rhythmic convulsions.
  • • Focal seizures: Localized activity that spreads outward over time.
  • • Absence seizures: A brief, global pause in activity.

Audio Feedback

  • • Soft tones: Normal activity
  • • Sharp sounds: Sudden seizure onset
  • • Complex harmonies: Generalized seizures
  • • Brief silence: Absence seizures
  • • Sustained tones: Tonic seizures
