During the last few years, intensive research efforts are being done in the field of brain interfaces to extract neuro-information from the signals representing neuronal activities in the human brain. Recent development of brain-to-computer interfaces support direct communication between animals brains, enabling direct brain-to-brain communication. Although these results are based on binary communication with relaxed requirements of latency and throughput, the fast development in neuro-science technologies indicates potential new scenarios for wireless communications between brains. In this paper we highlight technologies that are being used today to enable brain-to-brain communication and propose potential wireless communication architectures and requirements for future scenarios.
