Human-Human Interface

The Human-Human Interface is a classroom neuroscience kit for demonstrating EMG recording, motor neuron signaling, and electrical stimulation in one unforgettable human-to-human control experiment.

1. The controller flexes their arm, and the Human-Human Interface records the EMG muscle signal from the forearm.
2. The signal is amplified and sent through stimulation electrodes on the second person's forearm.
3. The second person's hand moves involuntarily, showing how voluntary brain commands become measurable muscle activity.

Students see how the nervous system turns intention into movement. The demo connects motor neurons, EMG signals, muscles, and stimulation in a way students can feel and observe directly.

• Voluntary vs. involuntary muscle activation.
• How EMG signals are recorded from the body.
• How electrical stimulation can activate muscles.
• How neural interfaces relate to neuroprosthetics and rehabilitation.
• Why nervous system signals can be measured, amplified, and used in experiments.

• Neuroscience classroom demonstrations.
• STEM outreach and museum events.
• University neuroscience labs.
• Human physiology lessons.
• Neuroengineering and neuroprosthetics introductions.
