  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. A recent development of
these interfaces is capable of direct communication between animals' brains,
enabling direct brain-to-brain communication. Although these results are new
and the experimental scenario simple, the fast development in neuroscience, and
information and communication technologies indicate the potential of new
scenarios for wireless communications between brains. Depending of the specific
kind of neuro-activity to be communicated, the brain-to-brain link shall follow
strict requirements of high data rates, low-latency, and reliable
communication. In this paper we highlight key beyond 5G technologies that
potentially will support this promising approach.
