Abstract: An apparatus and method for a pre-trained brain machine interface based on brain state data is disclosed. An initial session of determining brain state data during performance of a task by a subject at a first time is conducted. The brain state data correlated with task performance are recorded. A pre-training set of the brain state data is assembled. A decoder module of the brain machine interface system is pre-trained via the pre-training set of the recorded brain state data to decode intentions of the subject correlated with brain state. A current session is conducted at a second time subsequent to the first time. The current session includes the decoder module accepting a brain state data input of the brain of the subject, decoding a brain state output from the brain state data input, and generating a control signal to perform the task based on the determined brain state output.
