Zach Fredin and Joe Burdo has designed an electronic neuron simulator to help educate students of neuroscience.
NeuroBytes are tabletop electronic neuron simulators designed to help students understand basic neuroscience concepts. The platform consists of modular elements that can be freely connected to form biologically representative networks, and has been built from the ground up to be accessible to young learners without sacrificing the depth and sophistication that make it a valuable tool for college-level audiences. NeuroBytes are entirely open-source, meaning both the hardware design and the firmware that controls their behavior is freely accessible to anyone.
