Human-Human Interface
Control another person's hand with your brain — the demo no one forgets.
The Human-Human Interface is our most dramatic neuroscience demonstration. One person's brain sends a voluntary command, and through EMG recording and electrical stimulation, another person's hand moves involuntarily. It's safe, it's startling, and it teaches more about the nervous system in 60 seconds than a week of lectures.
How it works:
- Person A flexes their arm — the device reads the EMG signal
- The signal is amplified and sent to Person B's forearm via stimulation electrodes
- Person B's hand twitches — involuntarily controlled by Person A's brain
What students learn:
- How motor neurons transmit movement commands
- The difference between voluntary and involuntary muscle activation
- Electrical stimulation principles used in clinical rehabilitation
What's included:
- Human-Human Interface unit
- EMG recording electrodes
- Stimulation electrode pads (TENS-style)
- All cables and connections needed
Who it's for:
- Science teachers who want a wow moment on day one
- Neuroscience outreach and museum events
- University demonstrations
- Corporate and community STEM events
As seen in Greg Gage's TED Talk — over 10 million views. The single best way to get anyone excited about neuroscience.

Does Controlling a Neuroprosthetic Require Movement?
You want to move but cannot... can you still control others?
Active vs. Passive Movements for Control Signals
Can muscles produce measurable electrical activity without direct brain commands? Investigate how muscle signals differ between voluntary (active) and externally-induced (passive) movements!
