4. BCI - Brain–computer interfaces
	4.1. Definition and features of a BCI   4.1.3. The parts of a BCI   4.1.3.5. The operating protocol

Each BCI has a protocol that guides its operation. This protocol defines:

1) How the system is turned on and off
2) Whether communication is continuous or discontinuous
3) Whether message transmission is triggered by the system or by the user
4) The sequence and speed of interactions between user and system
5) What feedback is provided to the user.
