Brainwave Neurosim — interactive frontal EEG demonstration

Move the sliders to change the waveform components, change patient frailty and explore the EEG signature with increasing propofol and ketamine doses.

What the full version adds

• Additional agents

  Dexmedetomidine · sevoflurane (the demo covers propofol and ketamine), with a response-surface interaction model for combinations.

• Sleep stages

  N1 · N2 · N3 · REM, with spindles, K-complexes, sawtooth waves and the frontal eye movements.

• Epileptiform activity

  Sharp · spike-wave · polyspike · seizure, each with postictal slowing.

• Artifact patterns

  ECG pulse bleed-through · mains hum · gross movement · diathermy, each contaminating the trace and the spectrogram; diathermy also takes the Index out while it is live.

• Index — depth readout

  0–100, derived from the raw EEG, spectral edge and suppression ratio.

• Summary readout

  A plain-language description of the live trace.

• Display controls

  Change the gain, sweep speed, spectrogram colour window, column width and spectral-edge percentile, and see the same signal read differently.

• Export

  8-second clip: EEG, EEG + DSA, or the full window — with or without sound.

• Audio

  Sonify the displayed waveform.

• Quiz mode

  Test your knowledge against our growing library of questions.

• Second screen

  Open a live duplicate of the monitor in a second window and drag it to a projector or extended display.
