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.
