NeuroTinker LLC has developed a system to construct model nervous system based on NeuroBytes, small, neuron shaped circuit boards that each simulate the behavior of one neuron. An LED integrated into each NeuroBytes module provides feedback about its activity level. Neural circuits are constructed by connecting NeuroBytes together using excitatory or inhibitory âneurotransmitterâ cables. Similar to the real brain, these circuits can be triggered by environmental sensors and produce motor outp
