Brain-machine interfaces (BMIs) have the potential to improve the quality of life for individuals with disabilities We engaged in the development of neural mind-reading techniques for cognitive BUS to provide a readout of decision processes We trained 2 monkeys on go/no-go tasks, and monitored the activity of groups of neurons in their mid-brain superior colliculus (SC) We designed a Virtual decision VDF) reflecting the continuous progress of binary decisions oil a single-trial basis. and applied it to the ensemble activity of SC neurons Post hoc analyses using the VDF predicted the Cue location as well as the monkey's motor choice (go or no-go) soon after the presentation of the Cue These results Suggest that our neural mind-reading techniques have the potential to provide rapid real-time control of communication support devices.
