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. https://elecena.pl/product/30094035/human-human-interface 2026-04-16 https://elecena.pl/product/30094035/human-human-interface 2026-04-17 https://elecena.pl/product/30094035/human-human-interface 2026-04-18
