Have you ever dreamt of controlling the people around you? Family, friends, co-workers, even total strangers? Well now that power is yours thanks to the cutting edge of neuroscience and biotechnology, the Backyard Brains Human-Human Interface. With our electrophysiology setup, you will learn exciting neuroscience concepts first-hand as your brain sends an electrical impulse to your arm's muscles, telling them to move, and when your muscles move, this generates an even larger electrical signal. You'll take that electricity, then further amplify it and inject it into the nerves controlling another person's arm.

The Controller:

Your new Human-Human Interface is ready with all of the materials you'll need to connect yourself with another person. It comes with an Arduino microcontroller (it's like a small, easily programmable computer), already programmed to facilitate your newfound dreams of power. Plugged onto the Arduino is our Muscle SpikerShield, which lets the Arduino understand the signals coming out of your body. With this you can see the electricity in your muscles as they move, but more importantly, use them as a signal to turn on the stimulator.

The Controlled:

The sensation of totally losing free will can be a little weird at first, so just relax.

You'll be hooked up to the all-important TENS stimulation device, which harmlessly delivers electricity to your arm's nerves. The other person, the Controller, will be using the electrical signals from their voluntary muscle movement as a signal to turn on the stimulator. When this happens, your nerves will interpret the electricity as a 'contract' signal, and tell your arm to flex.

With all this, you're ready for fun and educational neuroscience experiments for students, kids, and adults.

Contains a TENS unit with modified cable for interfacing with Muscle SpikerShield, Arduino with pre-loaded code, Muscle SpikerShield that mates with Arduino, 1x orange muscle electrode cable with 3 alligator clips (red, red, black), 9v battery, 2 silver bags each with 50x electrodes.

Not recommended for use by persons with pacemakers or similar devices.

This kit is awesome. I know the price is daunting, but you are getting access to neurotechnology that is simple and easy to use out of the box. Most of us would never be able to build this ourselves. It is certainly capable of inspiring the next-generation of scientists. If we could only incorporate these types of activities into our schools more often- I'm sure that there would be a huge spike in science majors of all types!

Construct an argument that plants and animals have internal and external structures that function to support survival, growth, behavior, and reproduction.


Use a model to describe that animals receive different types of information through their senses,process the information in their brain, and respond to the information in different ways.


Conduct an investigation to provide evidence that living things are made of cells; either one cell or many different numbers and types of cells.


Develop and use a model to describe the function of a cell as a whole and ways parts of cells contribute to the function.


Use argument supported by evidence for how the body is a system of interacting subsystems composed of groups of cells.
