Editorial: Explainable and advanced intelligent processing in the brain-machine interaction.

Brain signals can be used to control external devices, such as computers, robots, or prosthetics via a brain-computer interface (BCI). However, decoding brain signals is not easy, because they are complex and noisy. In this research topic, the editors collected five articles that explore different ways of making BCI more explainable and accurate. It is hoped that this resource will spark further discussion, and ultimately advance the field.
