Detecting Silent Vocalizations in a Locked-In Subject

Table 2

Results of analysis of lower beta band peaks during Silent Singing. PSD% and frequencies are listed as the average result of all trials. “Latency” indicates the time (sec) after the speak onset signal in which the beta peak was evident. Minimum time segment indicates the period in which the beta peak was still visible.
